What is a Russound SB-3?

Now Dee, you should know all too well -- "there is nothing new under the sun". All of these designs, and their variations -- are older than anyone on this Forum. Well, except maybe Maron.

"...with the Rotel you just plug it's preamp outs into a high level input of his new preamp! I mean what is he going to do give up TV all together?" Shows you how HT ignorant I am.

I guess your original post was just really saying that if you're going to go with a SET amp (that you feel can't do the full range of things you like to do with your system) -- you're not going to throw almost 2 grand into it. You'd rather throw that kind of money at something that can give 100% -- to 95% of what you listen too.

George doesn't strike me as the high SPL type. He could definitely squeak by with 10 wpc and the RF-7's with movies. With the RF-3s, I wouldn't even bother. He's still left with the problem of giving up the processing functions of his Rotel, but if it was me -- the Rotel would be gone. I've been doing movies in 2 channel with tubes, and NO processor for two years -- and its awesome.

"I refuse to invest gobs of money in a amp that can not play whatever I throw at it with ease and do it all very well! not just certain types of music." Well, someone could come back and say that the monetary investment in the best iron and parts, results in a low power solution that can handle just about everything thrown at it. Did you read this yesterday when I posted it? Good article. Check out the graph. http://www.aikenamps.com/Crowhurst_blocking.pdf

I thought this was when he was going to use the receiver as a preamp, so he could utilize the processing section. I mean yeah, you're right -- 10 watts ain't gonna get it for DVD movies.

Relating to the new Klipschorns: I need to know the nominal impedance of the tweeter/midrange, and bass sections when run separately. Any informaton regarding swings in impedance would also be appreciated. If you don't want to post the information publicly, please email or PM me -- thanks. Dean

Hi Dana, It's easier is you just create a new topic, and make a 'for sale' post.

Good point. When the bullets start flying, I don't care if the guy next to me is black, white, or wearing a black and white bra.

Can you believe this Neo guy above me? Flames you for three days straight, and then wants you to build him some amps. I don't know Craig, are you competent enough to handle soldering a few caps and a handful of resistors? I mean, you can't even handle a freaking Eico.

Probably because when you were a kid, some loon had them hooked up to a 300wpc Crown pro amp. It's probably that POS NOS Valves amp. C'mon man -- 17 wpc If I remember the pictures, and the mods to your room (I think that was you) -- your house is just swallowing up the bass. I have you thought about going to 3 watts?

I can't believe Kelly just posted a picture of a 6922 based preamp. I gotta say though, after going to their site, I'm actually tempted to give the thing a whirl. I'm a sucker for that damn tube.

Dave, Yeah, but George doesn't strike me as the high SPL type. Besides, if it's not "enough" for him right now, it will be when he goes to the RF-7's -- and even then, the Wrights have good resale potential. He could start here and just be happy as a lark. Kelly, That's an interesting little unit. What have you heard about it?

There are lots of good preamps, but Friends is right -- when you get into an area like this, it's usually not a bad idea to get the pieces that were voiced together as a whole. So, since there is a Wright preamp out there, it's the 'natural' mate to the amplifiers. It's also nice from the asthetic perspective. Those Wright monoblocks are push-pull, with 10 wpc. They are true triode however, and the first 6 watts are Class A. In a world of compromises, it may be the best option for you with the RF series of speakers, in your room.

I heard the ALKs on Paul Parrots Klipschorns last month, and still contribute much of the great sound we head to the crossovers. I've never heard Heritage sound so "flat" (good word) and "non-peaky". Just beautiful. Anyone running tube gear really needs to be using these. Al did a bang up job by getting a nice impedance curve -- a must with SET amps, and most tube gear I think.

I stand corrected. Does that mean all circuits are "filters"? I had them on the phone once, and that is what they told me. That's what I get for not thinking for myself.

I've rebuilt the crossovers in my RF-7's several times, and learned some hard lessons along the way. Considering the prices of some of these caps, I figure why not just use the cap with the best materials and contruction? Turns out there is a correlation between quality of material/construction and sound. Imagine that. I've rebuilt about a 1/2 dozen speakers now, and have used a variety of parts in each -- and the RelCap Theta has always brought pleasing results. Solens sound grainy, Auricaps thick and syrupy, and Hovlands zingy. To my ears anyway, the PPT Thetas sound the most natural/neutral. I'm talking in the tweeter circuit here, I don't get too crazy with the bass -- it gets waaay too expensive. Before/after pictures of the first set of DQ-10's I did, followed by the RF-7 crossovers.

I'm gonna pass Craig. I'm eating, and then I'm going to crash. Give me a call at work tomorrow.

Where did I "moderate"? By telling you to spend more time critiquing your own posts? Whose business am I in? Lucky you, I won't be responding to anymore of your idiotic posts. Have a good evening.

Helluva good post for a "rookie". How's that treble doing?

LOL Klipschfoot -- look closer God is now here.

Options I completely forgot about -- good job guys!

Well, I was going to bow out. You may have to exhibit some patience -- after all, you are just now getting your feet wet with the tubes thing. The information you lifted and posted here has some truth in it -- but it does not account for all situations. For example, your room is 20 feet long, and the RF-3's, though fairly sensitive, have some swings in impedance that aren't necessarily favorable to SET operation. It's hit or miss here, since room acoustics can help balance things out. Also, depending on how far away you sit from your setup, the RF-3's may have some trouble filling the room with such low power. This doesn't mean it couldn't work, but it might be a challenge. Why not try a nice vintage integrated for now just to see what you think? You would get to try tubes, and keep the Rotel as well. Later, when finances permit -- you could make your jump to SET, and buy something you won't out-grow.

Without getting into another full blown discussion regarding the relative strengths and weaknesses of the various amplifier topologies, let me just say that you set a financial limit of $500. SET would definitely fit your musical tastes and habits, but this option is just more than you are willing to spend. You are looking at $900 on the used market, and that doesn't even include the cost of the preamp you would need. I suppose you could do the Paramours, but even those are beyond your reach right now. Anyone? I'm bowing out now.
