Get yourself a nice tube preamp to go with that Dynaco and it will take a bit of money to better it, and even then -- you will be in diminshing returns territory -- trading a stack of green for small lateral shifts in signature and an additional hair's width of transparency. A used AES AE-3 for around $350 would do nicely. It's not really fair to compare the Scott to the Dynaco ST-70 unless you have a better preamp than the PAS3.

Like everything else I've been doing over the last year -- trying different things just to see for myself if the differences are as earth-shattering as some claim -- I will probably make a move back into vinyl over the next year. Of course, vinyl isn't new to me -- and back in the good old days I had a pretty pricey MC setup. I still hear a pretty decent MM setup every now and then, and personally -- I don't see what the fuss is all about. I mean, vinyl recordings have compression too, and though the top end isn't quite as 'splashy' -- dynamics are lacking. Heck, I still remember terrible sounding records -- Am I the only person that remembers this? Still, it would be fun I suppose. I was kidding about Chevelle on vinyl -- I was taking a tongue in cheek stab at Craig. I don't consider most of what I listen to as Metal -- I actually only have two Metal recordings if you can believe it. It's Alternative, and it sounds good on the RF-7's. I think some of the new stuff is a hoot. I don't like all of it -- but there are about a half dozen bands that seem to have it together. I listened to Genesis Seconds Out the other day, and listened to ELP's Brain Salad Surgery when Dave paid picked up the Cornwalls. Cymbals sounded as good as anything I remember from those recordings on record. Chevelle has some good words -- which shouldn't come as a surprise since the words come from a Biblical/Christian world view. Chevelle band members are actually Born Again Christians. Same goes for Kutless and East-West. So, no Satanic chants from any of these guys -- How does DVD Audio on the RB-5's stack up against the Chorus setup Rick?

Can I get Chevelle on a record?

I think most would agree not to use a Solen in a critical part of the signal path. Ever wonder why they are called "self healing"?

It's nice to know a Solen doesn't sound any better than an oil cap not designed for audio. I don't use the Solens for other reasons -- guess I an add this one to the list.

I don't know why everything always has to be so complicated: If the speaker is called by "a name" -- it's Heritage. If if has a letter/number -- it's not.

Hi Lloyd -- thanks for popping in. Considering the low power of the Stealth I'm surprised you didn't opt for a DHT in a SET configuration -- seems this is the rave these days. I know George Wright also likes the octals -- but does use the 2A3 in his power amps. If you wouldn't mind, would you elaborate on why you chose a low powered push-pull over SET? I noticed the very high damping factor and low distortion specs -- I would imagine there is considerable local feedback. I know Mike Sanders of Quicksilver used almost 25db of negative feedback in his Horn Monos. Many feel that a liberal use of negative feedback kills the transparancy or "see through" imaging of an amp. The most popular amps are zero feedback. Any thoughts you would like to share on this? Most here are fairly open-minded. I have used high powered SET (18wpc using the KRB300XLS), a zero feedback Class A push-pull using KT-88's, a straight up pentode push-pull, and have settled in nicely with a pair of monoblocks running in Ultra-linear with EL-34's. Of the three amps -- the latter are my favorite. Nice stuff Lloyd -- but you need to change that "Mother's Against Drunks" logo. Why not a nice silk-screening with cursive/script?

Yes, I am an ***, and I'm getting worse everyday. Time to repent -- or in the modern day venacular, turn or burn. No TT for me -- I already owe too many people money. Still owe Jazzman for the preamp and still owe Craig as well -- besides, no phono output.

Man, Craig's been holed up in his workroom so long I'm surprised he even remembers how to do a remodeling job. Better be careful -- he might try to solder your house back together. I've been tempted at times to get a turntable just so I can hear those Zep'lin 180 gm. reissues -- some of the worst recorded stuff on digital ever.

Is what you just explained known as "upsampling"? If so, thanks -- I've been wondering how that worked. Tell us about your new player. I'm curious (as always) regarding your impressions of the lastest generation of DAC's.

Nope, you meant me alright. My objection wasn't so much where you posted -- but what you were posting. It seems to be the pattern over in the General Forum -- a post dealing with a specific issue takes a bizarre turn and turns into a big long flaming thread. However, since your intention wasn't to start a nutty thread like that -- it's a mute point. Don't worry about. At any rate -- still checking out the Korato stuff. This thread will eventually get back on track.

Tom, Don't be offended, but you don't have K-horns, Belles, Scalas, or even RF-7's. Run those amps the way Hafler intended. Your RF-3's will thank you. Leaving them in Ultra-linear gives you 7-10 watts of Class A, raises your damping factor, and gives you some much needed headroom. Keep in mind that you need 40 watts to do what a Heritage Big Horn can do with 10.

"...my point is that we ship our manufacturing to other countries..." It isn't our manufacturing -- it's their manufacturing. I don't see Cary Audio, Sonic Frontiers, etc. sending their manufacturing anywhere. Good products (from anywhere) simply raise the anty, drive competition, and create a stable and fair market. Please take your bantering to the General Forum -- if and when it ever comes back. Maybe you should take the factory tour at the kr site? www.kraudio.com Oh yeah -- I see oodles of Americans lining up to do this work. There would be no tube audio without the East.

I agree with that. Let's get real here -- after the first reflections it's poo-poo. Time alignment with the DQ-10 is especially suspect when one considers that between 8% and 12% of the total output reflects off of the back of the grill into the sound path. I know Dahlquist chose 1st order networks because of something related to phasing -- but I can't remember the details. I do know the crossover has some wierd things going on it that I've never been able to figure out. Everytime I build a board for a pair I spend a lot of time under the board soldering positives and negatives together. Something I thought of while reading the article was the issue of lower IM distortion by using the deep slopes. Even without the math, much of it was still too deep for me -- but still fun to pour through (several times in fact). I of course wonder if the RF-7 would benefit from something like this -- especially the use of the autoformer. However, I have neither the background nor patience for investigating it. Hell, I can't even figure out how to mod the crossover to allow for the use of higher gauge litz wire in the tweeter circuit. No, this is not a cry for help -- I want to listen more and work less! Something for you Engineers. Understanding Engineers - Take One <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Two engineering students crossing the campus when one said, "Where did you get such a great bike?" The second engineer replied, "Well, I was walking along yesterday minding my own business when a beautiful woman rode up on this bike. She threw the bike to the ground, took off all her clothes and said, "Take what you want." "The second engineer nodded approvingly, "Good choice; the clothes probably wouldn't have fit."

Understanding Engineers - Take Three A pastor, a doctor and an engineer were waiting one morning for a particularly slow group of golfers. The engineer fumed, "What's with these guys? We must have been waiting for 15 minutes!" The doctor chimed in, "I don't know, but I've never seen such ineptitude!" The pastor said, "Hey, here comes the greens keeper. Let's have a word with him." "Hi George! Say, what's with that group ahead of us? They're rather slow, aren't they?" The greens keeper replied, "Oh, yes, that's a group of blind firefighters. They lost their sight saving our clubhouse from a fire last year, so we always let them play for free anytime." The group was silent for a moment. The pastor said," That's so sad. I think I will say a special prayer for them tonight." The doctor said, "Good idea. And I'm going to contact my ophthalmologist buddy and see if there's anything he can do for them." The engineer said, "Why can't these guys play at night?" Understanding Engineers - Take Four What is the difference between Mechanical Engineers and Civil Engineers?

Understanding Engineers - Take Nine An engineer was crossing a road one day when a frog called out to him and said, "If you kiss me, I'll turn into a beautiful princess." He bent over, picked up the frog and put it in his pocket. The frog spoke up again and said, "If you kiss me and turn me back into a beautiful princess, I will stay with you for one week." The engineer took the frog out of his pocket, smiled at it and returned it to the pocket. The frog then cried out, "If you kiss me and turn me back into a princess, I'll stay with you and do ANYTHING you want." Again the engineer took the frog out, smiled at it and put it back into his pocket. Finally, the frog asked, "What is the matter? I've told you I'm a beautiful princess, and that I'll stay with you for a week and do anything you want. Why won't you kiss me?" The engineer said, "Look, I'm an engineer. I don't have time for a girlfriend, but a talking frog, now that's cool."

"Have no fear, I left out the math!" LOL -- thank God.

Yes, I'm finally getting around to trying your resistor trick. I'll be doing it next week. Should be interesting.

Hear, hear -- hats off to you Al! I can hardly wait for the headache I'm going to get trying to decipher the paper.

Leo, Would you care to elaborate a little on what Jeff is inferring to regarding the use of transformers. Is this simply an impedance macthing mechanism that accomplishes pretty much the same thing as your 8 ohm resistor across the output connections on the amp?

About 15 minutes -- then wipe them down and make sure they are completely dry. uh -- this is usually for dirt poor teenagers who have to wait for their next allowance before they can buy strings again.

You are talking about a really cool thing that I've never really understood -- transformers in speaker crossovers! I don't really understand how you can not use cables though, don't you still need something between the amps and crossover? Sure would be nice if Leo would jump back into this thread -- he's the guy you need to talk to. Sounds like you two could converse on the same level. I'm not always much of an original thinker when it comes to this stuff. I beg, borrow, and steal everyone else's ideas! My crossover is still the Klipsch crossver -- just a point-to-point wired version with higher quality parts. Nothing fancy going on here. There are only two parts that deviate from the original -- only slightly, for the purpose of controlling silibance in the horn. Well, there is that huge 14AWG inductor for the bass -- does that count? I'll shoot Leo an email and get him in here.

It kind of works like baking the tubes I think. Boiling the strings gets all of the crap off the strings and actually shrinks them down back to where they were when they were new. It only lasts about a week or so -- but works.

I used to boil my guitar strings when I didn't have money for new ones. You might try that instead.

I miss Kelly, he was a hoot. I also miss being called 'freak' and 'loon'.

Tell me about your preamp (Citation)? The Rocket needs considerable gain. Though undoubtably a great amp -- The Rockets often show up on Audiogon because people mate them with inappropriate preamps. I love the Cary gear -- buy you might want to shy away from this particular amp. If you are new to tubes and don't have developed soldering skills -- you might want to hold off on the kit idea for a while as well. Would still like to know more about your preamp.
