Anyone Bi-amping with tube high & solid state lows

I'm doing this. My speakers are Martin Logan Odyssey, the amps are a Classe CA-200 for the bass and a Counterpoint SA-220 for the top. The speakers are set up for biwiring/biamping, so that was easy. My preamp is a Counterpoint SA-11 and it has three sets of outputs so that was also dead easy. One set goes to each amp, the third set goes to the subwoofer inputs. I use the crossovers in the Odyssey. Level matching started out a little tricky but I also got incredibly lucky in this area. Although the spec ratings for the two amps are fairly different (7 dB) measurements showed that they were close to 2dB apart, with the bass amplifier a little too hot. Then I remembered that the speakers have a 3dB cutout switch. This is intended to help in bass-heavy rooms, but in my case it turns out to only cut bass by around ... 2dB! Incredible luck.

I biamp with Sonogy amps for 220hz on down and Lamm ML1s above that, but I have an active crossover and a 4-piece system. There are always some potential sonic continuity problems, particularly with a crossover point that high, which are minimized by this combination, but I agree with Eldartford that the sonic characteristics of the amps, while potentially noticable, are not as big a problem as you might think. If you don't have an outboard active crossover you may run into amplifier input sensitivity and gain problems, though (for example, when I replaced my Jadis amps with the Lamms, I had to reduce the bass level on the crossovers significantly because the Jadis had a higher sensitivity, and thus subjectively played louder with less input, than the Lamms).

Wavac md300b tube amp on the horns ,threshold t100se on my bass towers ,works great tried tubes they sounded nice but where a bit weak in the low bass .JK

Meech33, why not try it and tell us what you come up with on your end?! I would like to know your results. YOu could easily pick up even a modesly, yet excellent sonic tube amp and solid state combo for great sound. But, I would like to know your results. Let us know if you do.

I will do that. I'm planning keeping my 205 wpc Parasound HCA-1500a for the bass. The amp I'm looking at is a single-ended-triode from WWW.Space-tech-lab.com

The amp has only 2wpc but the speakers they'll be powering are pretty efficient. (Coincident Triumph Signatures 94db)

I will definately let you guys know how it turns out.

Thanks for the info.
