    System #214 (SL3)

    You have a beautiful system -- in some ways similar to mine, but a bit "bigger". Then of course there's the traditional ARC vs. C-J rivalry, but I'm willing to overlook that if you are ;) Is that a mk IV with a JWM 9? Sweet! Also, how do you like the Alpha? I've been considering one of these...

    Need help biamping SL3s (tube/ss)

    Hi Bernard, Thanks for all your input. My understand is something like the left image here. I guess I see what you are saying, and yes, this is a more accurate/exact description than mine. I was only expressing the realization that I needed two resistors, one which you could consider "inline"...

    Need help biamping SL3s (tube/ss)

    Hi TJ, Thanks for the info. From the thread, it appears that you tried biamping with compensating for the differing amp sensitivities, and found that you had poor balance between highs and lows (not surprisingly). If I read correctly, it appears that you came to the conclusion that your...

    Need help biamping SL3s (tube/ss)

    SL3 Amplification Hi Raanan, I don't doubt that -- the EP1500 is a very powerful amp, some 10x more so than my humble Conrad-Johnson. I'm sure it drove the SL3s quite easily. I think we simply have a different approach to system building. I've got a C-J tube preamp (PV12A) and am trying to...

    Need help biamping SL3s (tube/ss)

    Hi Spike, Excellent! I should have thought of this myself (and doubtless would have, were I only a little more clever). But this is something I can start with -- I'm looking for 4.3 dB attenuation. I should be able to figure out how to make something for that -- maybe a single vishay resistor in...

    Need help biamping SL3s (tube/ss)

    Right, of course -- I was talking about actually determining what the proper levels/settings would be (more in the direction of Jonathan's suggestion of pink noise and an SPL meter). Sorry if I was unclear. But I believe profoundly in a minimalist signal path, so the less I have to insert...

    Whats more importnat to upgrade Amp or pre-amp?

    I think this is right on the mark. For decades, I took the opposite approach: focus first on the source, then on the preamp, then the amp, then the speakers. But you know what I found, when I got to the end? That the synergy between amp and speakers may have the single biggest impact on system...

    Need help biamping SL3s (tube/ss)

    Hi Khenegar, Thanks for the feedback. I thought about this initially, as well. In fact, I *did* try the Premier 11 by itself, without biamping, and felt that it was struggling a bit. I'm not sure if the problem was the complexity of the load or the CJ's lack of (adequate) current or damping...

    Need help biamping SL3s (tube/ss)

    Hi Raanan, Thanks for the reply. Yes, it occured to me that I could add a crossover, but (a) I'm trying to keep a minimalist/purist signal path and (b) that still doesn't solve my problem of how to correctly compensate for the differing amp sensitivities.

    Need help biamping SL3s (tube/ss)

    Hi Jonathan, Thanks for the response. I've got a Radio Shack SPL meter and a test CD with pink noise, so I guess that ought to be enough to get balance. But I can't think of an obvious/easy way to provide variable attenuation. I have a second (active) preamp that I could insert between the...

    Need help biamping SL3s (tube/ss)

    Hi, I've got a pair of SL3s and recently picked up a tube amp that I'd like to try to use to drive the panels. The tube amp is a Conrad-Johnson Premier 11A, which I'd like to try to mate with a Musical Fidelity A3.2CR driving the woofers. I'm doing this passively, using the internal crossovers...
