Looks like the labor charged on Craig's next Scott amp is going to be around $1800 Pat -- I missed what happened with the K-horns. Were these black ones? What happened?

Interesting post, especially your findings regarding sensitivity. The RF7's should be considerably more dynamic. Is this not true?

Cool stuff. I need to get me one of those funnel caps liked Clipped is wearing. Deep stuff. Lot's of meat and potatoes. Why sure, there is no limit to the human imagination. If it can be thought, it can be done. If humans have the capacity for great imagination and intelligence -- then I see God as being the source from which all things flow. God is not "intelligent" -- He IS intelligence itself. I see creation as the canvas on which God did his painting, and just as the artist stands outside of the canvas as he does his work -- so God is. A mind greater than our own is at work here. We can barely comprehend the mechanics involved with the functioning of all things -- and yet we would deny the POSSIBILITY of a Creative Agent? Doesn't "order" and "design" point to this? Can there be order without an ordainer, or design without a designer? Entropy is a steel trap. Yes, life involves a rapid building up of energy using complex material into organized forms. However, at some point it stops -- and Entropy takes over. There is a rapid building up, followed by a gradual slowing down, and then a complete reversal. Truly, there are no "closed" systems. http://www.icr.org/pubs/imp/imp-040.htm Also, gravity is having it's own problems with Entropy. The universe is rapidly expanding, but it is not expanding the way most people think. It is not just moving away from the "center" -- but all material is also increasing distance in relationship to the material adjacent to it. It is like a balloon with dots on it, and as you blow air into it -- all of the points on the surface of the balloon start moving away from each other. Some of us believe that when all usable energy has been depleted, the whole thing will snap back on itself like a rubber band. "The sky receded like a scroll, rolling up, and every mountain and island was removed from its place." Evolution and Humanism do a rather poor job of explaining the bigger picture, or offering real solutions to managing the faulty mechanics responsible for the "broken" human condition. Evolution has major problems, most stemming from the fossil records, dating methods of rocks, and observable biology. Humanism brings with it this idea that we can somehow pull ourselves up by our own bootstraps. Alas, this simple minded fool has trouble with much of this. A final thought -- If anything we imagine can be possible, and we "imagine" God -- doesn't that mean He could be? I did enjoy reading your posts Clipped, and I'm glad you shared the thoughts.

Dammit Ed, you almost made me cry.

Thoughtful posts, but I think maybe you guys missed my intent. I really put some thought into that first post, and it's a shame that folks have such a difficult time with Biblical concepts and words. Words are vehicles of thoughts, and you can't really understand the thoughts unless you know the meaning of the words. I often make the mistake of assuming people understand the terms. The word "sin" means "missing the mark" or "falling short". It is not a word used to issue condemnation, but to merely point out a fact regarding our "condition". Most humans ARE basically good, but they are not perfect. The first humans were perfect, but something entered in that "corrupted" or "adulterated" the original design. We are therefore seen as being in a "fallen" state. I use entropy as evidence of this. In spite of how "good" we strive to be, there is disease, suffering, and death -- and these things were not part of the original natural order. Metal rusts, wood rots, asteroids break apart, etc -- all "unnatural" events from the Christian, Biblical perspective. I would like to point out that if everything is so peachy-keen, and everyone is A-O.K. as is -- then why this "need" to be good. What is with all the "striving"? One of Chris' points should point to the obvious: Random acts of kindness are not the norm. Why not? And why does someone look for the "catch" when a kind act is performed? You see, something is amiss with us. Kelly, the part of the post you found agonizing was actually intended to create the complete opposite reaction. You remind of how my dad used to respond if I brought something up. I knew the reason he reacted the way he did was because he had images of televanglists dancing in his head. If you read the post again, I was basically asking to focus on the true intent God had through Christ, and not to focus on those who use Christianity as a means to further their own ends, or who use it to hurt others. I am a person very much in the spirit of what Chris believes. However, I also believe the Bible is important, and I enjoy reading it. The Gospel has some "bite" in it, and retaining the fullness of the message makes it honest. The second post was in response to Clipped who indicated "I didn't get it". I was trying to tell him what he "wasn't getting". Missed by you guys was the great passage where God says He was was pleased to save, by the foolishness of what was preached. Seems God full well understands how this whole thing is viewed by most. Kelly, your Hanna Babara comment was funny -- especially since I made mention in my first post about how those respond when the whole thing is explained to them as a child understands it. Again, pick up a copy of Lewis' Mere Christianity.

Craig, I'll give you a call later tonight. Something Leo touched on, that hasn't really been discussed, is the peaks. How bout going from say 3.9 ohms to 30 ohms? How about them K-horns on SET amps -- they seem to do O.K. Think I'll just stay on those 4 ohm transformer taps. Going to the 8 ohm taps just brings in a different set of problems. As it is, the sound is fabulous, and is pretty much where I want it -- dynamic, articulate, and oh so wide open. I've learned my lesson -- I'm leaving it the hell alone.

I realize I am a mere child here, but I have been living off of the archives at the SET Asylum over the last couple of days. I just read an interesting thread last night, and it was being said was that using the 4 ohm taps on the transformer to accomodate the low impedance points of a speakers impedance curve is almost always better than using the 8 ohm taps. The result is supposedly lower distortion levels because the tubes aren't being driven to their maximum output the majority of the time -- and only rarely are they driven to their limits or slightly beyond. Another advantage from this is extended tube life. OTOH, using the 8 ohm taps, though giving some elevated power output, actually increases distortion levels dramatically, as the tubes are being overdriven whenever they are forced to deliver current beyond their operating parameters to accomodate the low impedance. Something I thought of last night (completely on my own:), was that the question really shouldn't be, "How many points on the curve does the speaker swing low", but rather -- "How often does the music take it there." I mean, we see an impedance curve with 3 or 4 low spots on it and think, "Well, that's not so bad." But what if the music has content that takes it to those 3 or 4 frequencies 90% of the time?

"I will destroy the wisdom of the wise; the intelligence of the intelligent I will frustrate." "Where is the wise man? Where is the scholar? Where is the philosopher of this age? Has not God made foolish the wisdom of the world? For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe. Jews demand miraculous signs and Greeks look for wisdom, but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles, but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God." "See, I lay a stone in Zion, a chosen and precious cornerstone, and the one who trusts in him will never be put to shame."Now to you who believe, this stone is precious. But to those who do not believe, "The stone the builders rejected has become the capstone," and, "A stone that causes men to stumble and a rock that makes them fall."

They sure look like 9 ply from the front -- I'll post some pictures a little later. I really love 'em, but I'm not going to have room for them with those Cornwalls sitting down there.

Well, I'm selling my 83's, and they're pretty nice. See my ad on the 2-channel forum. You can email me at sevenwescotts@aol.com

I had a buyer who said he was interested and wanted me to figure shipping. I have sent several emails since yesterday and have not heard back. My last email stated I was giving him until tomorrow morning to respond, and then I would have to move on. I also opened a Fedex account, which does brokerage for customs. This means I can ship to Canada now. Rough esimates show I can get both pieces to Canada for right at $100. Anyone still interested, please email me at sevenwescotts@aol.com. Get in line, first come first serve. BTW, I've had several ask me why I'm unloading the sub. Well, I have Cornwalls coming into the house, and space is limited. This, coupled with the fact that I listen to a heck of a lot more music than I watch movies, has made me decide to give it up. No, I won't have foundation shaking bass with the Cornwalls -- but music I listen to rarely goes below 35Hz -- so I'm covered.

I was going to run my future Cornwalls with the Heresies in a quasi-multichannel setup. I've decided to eschew this idea for now. Basically, I don't really have the room to accomodate the Heresies in the way originally imagined. They are oiled oak with 9 ply birch plywood. These were made in 1983, and are in very good condition. There are just a few small indentations along a couple of the rear side edges, that are not really noticeable unless you turn the speaker around or run your hand down the edges. There is one very small chip on one of the rear corners, which I will fix before sending it out. The risers are in mostly good condition, with the exception of a little bit of veneer along the very bottom starting to peel. Again, not really noticeable with the speakers sitting on the floor. The brown cane grill cloth is perfect, with logos intact. All of the highly visible parts of the speaker look perfect. They sound wonderful. $525 shipped, which is exactly what I paid with shipping from the eBay auction I won.

Gee, cute little unit. At 15lbs it hardly qualifies as a paperweight.

The magnet wire I've been using is 19 gauge. I've read the threads on the Asylum using the 30 gauge in single conductor format, as well as aggregating it in a multistrand configuration. Reviews using these two methods produced mixed results. I think 30 gauge single is too much of "less", and the multistrand configuration defeats the whole purpose of keeping it simple. I do think there has to be a little bit of "meat", or substance to the conductor, the trick is finding the right amount -- without underdoing or overdoing it. Right now, I'm staying with the 19 gauge, until I can fully understand what Risch is trying to accomplish with the Cross Connect. I understand the main purpose of cross connecting is to lower the inductance, but most cables have relatively low inductance anyways. I'm betting most of the good sound is simply a result of using solid core copper and a superior dielectric. I've been reading quite a bit on dielectric material, and though foam Teflon is considered the best for the coax type cables like Belden, most seem to think natural fibers, such as cotton are better. Even better still is air -- bare copper, no shield, no nothing. Hmmm. Or should I say hummm. I like the Magnet wire. The enamel is applied directly to the surface of the copper, and since 65% of the current rides the top of the conductor -- it seems reasonable that a material in direct contact with the copper would yield the best results. So far at least, I'm very pleased with the results. As far as silver goes. My Music Metre Silvers use (6) six 18 gauge .9999 solid silver conductors -- and they sounded excellent on the Heresies. Uhh...well, last night they did

I'm marching to the beat of a different drum because I listen to the beat of a different drum. Having decided at one point that cables made very little difference, I decided to revisit the subject after removing the Silvers from the RF-7's and replacing them with the straight Magnet wire. The Apollos and RF-7's reacted very strongly to this change, and I found myself a little confused. I decided just to have some fun, and instead of stressing out over the fact -- I simply enjoyed the experimentation. I discovered when relaxed, and just enjoying the tunes, changes that I once thought were too subtle to worry about, now seemed much more magnified. At evenings end, the Silvers, the MITs, and several variations of stranded wire were heaped in a rather large pile at the end of the room. The SET amps driving the RF-7's, really do seem to favor a thinner gauge, solid core copper cable. I was very pleased with the outcome here. The Silvers, though softening things up, were also snuffing out dynamics. It didn't seem very obvious until I reverted back to the copper stranded. Later, I removed all of the stranded cable and put in the solid core magnet wire. This produced the most dynamics and solid treble reproduction without smearing at the the higher SPL's. With the Silvers, I couldn't hit 98db without feeling like I wanted to grind my teeth down. Last night, I was producing a clean, effortless, unstrained sound at 105db. So, to my utter dismay, the "problem" did not lay with the SET amps -- but the wire. Actually, It wasn't really the wire -- but the combination of wire, amp, and speakers. The "problem", in the event you are not aware, was this sense that the Apollos just weren't "putting out with the RF-7's". Evidently they were, but the Silvers were somehow restricting dynamics and CLEAN treble immediacy. Again, I should have pegged this pretty quickly, as putting in the Silvers was the only major change I had made since getting the Apollos. I was initially blown away by them, but then after getting the Heresies, the damn things almost sounded "muted" in comparison. I don't think I will be commenting on the sound from changes in my system anymore until I've spent several hours listening. I liked the Silvers when I first put them in, and maybe in this hobby it is true to say -- the first impression isn't the last of it. The Heresies OTOH, responded very well to the Silvers. The edginess exhibited on the RF7's did not exist with the Heresies when using these cables. I have no idea why this was. I will be putting the magnet wire on the Heresies tonight to see how they respond. Before it is all said and done, I would like to make some Cross Connects, as well as try a very simple cable like the Audioquest Type 2's. At any rate, all is well on the launching pad, and I'm quite content with what I have coming out of the RF-7's and Apollos. Some additional GENERAL thoughts here: Horns and SET seem to favor very simple cabling structure of the solid core type. Less seems to be more, with a huge thumbs down on the thick stranded stuff. Birwing seems to be out. Each time, the single wire config sounded more open and dynamic. Jumpers need to be the same wire type as the main cables.

It took a little heat off of the upper treble, other than that -- there weren't any other differences.

Boss, Since there is most certainly a God, I'm sure Chris' AE-3 will be for sale soon. You should claim this preamp now if at all possible. It is a very fine piece, and you will not do better for the money. No way. However, you will not have a phono section with it -- it is a linestage only.

Mike, I'm pretty familiar with Jon's site -- I didn't remember anything about magnet wire for speaker cable out there, but went out just the same. Didn't see anything.

Leo, I've concatenated some posts out of another thread that you may not have read yet. The other thread is slow to load because of all the pictures in it. I originally asked the question if there was a way to tell how much power was going across the speaker terminal inputs from an amp. I've been dealing with a bit of a paradox -- and wanted to see what you thought. Dean, Without a scope you really can't . But I found one thing out as pertains to you using the 4 ohm taps. With tube amps they produce there rated wattage at all taps unlike solid state. The only way the rated output changes is if you hookup a 8ohm load to the 4 ohm tap and create a indepadance mismatch. So if your RF-7 are indeed a 4 ohm speakers hooked to 4 ohm taps on the Apollos or the Scott your actually getting the rated output. Also if it seems like the amp drops over all output using the 4 ohm taps then your RF-7s are not 4 Ohm speakers ! Craig Craig, The bottom line is this: Since the RF-7 has those low spots, it is best to accomodate them by using the 4 ohm taps. The overall output of the amp is halved, however -- it will deliver the necessary current when the impedance drops without attenuating the frequencies at those positions. At least, that is my understanding at this point. Running the RF-7's on the 8 ohm taps will generate more current overall, but the frequency response will follow the impedance curve at those instances where the impedance drops. My question asking if there was a way to tell what was going on at the terminal inputs of the speakers -- was for the purpose of validating the math. Now, for the paradox. I've been running the Heresies on the Apollos since last night. The Apollos are wired in 4 ohm internally. I can't change them on the fly. I would have to remove parts and then resolder. I get clean output on the Heresies up to 105db. In fact, it sounds very good. There is no sense of strain or evidence of clipping. The sound is dynamic and crystalline. To be honest, compared to the RF-7's, the sound comes forward with less effort, and as far as my ears can tell -- sounds better at 105db than the RF-7s at 100db. At 100db, the RF-7's begin to harden up, and have me grinding my teeth. So, why do the Heresies generate more output with no strain, then the RF-7's? The really odd thing, is that the Heresies are 98db/w, and the RF-7's are 102db/w. The Heresies, an 8 ohm speaker wired to my 4 ohm taps -- are taking the fullness the Apollos have to offer completely in stride (and according to the information in your post, should be an impedance mismatch, thus choking off the Apollos). The RF-7's OTOH, sound really great until they go over that 95db - 96db barrier, and then they start to sound, well...like $hit. The only way I could get the RF-7's to match the output of Heresies and Apollos, and have them maintain a semblence of integrity in their signature -- was with the Aragon. The Apollos definitely sound better at 95db and under -- but above that, the Aragon delivers a dynamite sound. I'm just trying to sort some things out here, and will also be emailing Leo about this. I'm beginning to wonder if some of this might have something to do with sheer mass of drivers in the RF-7, and possibly the additional parts and complexity of the crossover as compared to the Heresy. I don't know. It's odd. At any rate, I'm looking forward to putting the SET amps on the Cornwalls. It may be that this where they belong. I would then of course put the Scott on the RF-7's -- where I think there might be less problems. Don't know, don't know.

Seems some people think the enamel covering the copper on Magnet Wire is the ulitmate dialectric. Many are using it for speaker cable, interconnects, and the internal wiring of speakers. I did cut 16 inches off of one of my unused inductors utilizing 19 gauge copper. I made four, 4 inch jumpers for the RF-7's. It certainly sounds a little different than both my stranded Vampires, or the stock Monsters with spades using the stranded Z wire. I thought it was interesting that I could tell a difference, since the Vampires and Monsters sound the same to me. Any thoughts on this?
