Tube amp for "difficult" speakers,,,

I know an older gentleman who used to own Consequence. He has gone thru many amps, from high power solid state like Bryston 7B-ST to a 70wpc tube amp. His favorite was the medium power tube amp that was made in Canada, but the company has gone belly up and I can't remember the name at this moment.

I used to own Confidence 5 which many believed are the modern iteration of Consequence. I have tried 10+ amps on those and I would not recommend tube with them. The best tube amp I had success with was Sonic Frontiers Power 3, but even then they could not fully bring out the bass.

If you are not dead set on Consequence, I suggest you look for a new speaker that has more resolving power, quicker, more transparent, and easier to drive. As much as I loved the Confidence 5, I have moved on and much happier now.

Tvad you must be right because I experience a lush midrange with plenty of balance,weight,and lucidity in both mid and low frequency.

Your VAC amps are considerably better than were mine, and they use 300B tubes, which have the characteristics you describe. Do you know the impedance specs of your speakers: lowest, highest and nominal? That'd be helpful for anyone reading this thread.

Tvad I don't have the specific info at hand but my speakers are a good match to my VAC 70/70. Just for others,I found this article on the VAC website.

Sound Lab (and all true electrostatic speakers) are a difficult load for the previously mentioned reasons. However, there are tube amps that are very capable of driving them extremely well, Wolcott, Atmosphere and CAT being good examples.
