The Battle between Stiffness And Damping Of The Speaker Enclosures!

In the 6moons review on page 4, they said they used a 300B amp with only 8 watts and it worked just fine and their room is not small.

If the specs are correct, then this was entirely inappropriate use of an SET, since it would have been making a lot of distortion to make significant (above conversational level) output. Because much of this distortion would have been higher ordered harmonics on the transients, I bet they were saying it sounded really dynamic. But because the ear uses the higher ordered harmonics to sense how loud a sound is, what was really going on was the distortion masquerading as dynamics.

Some say these Volya Bouquet Loudspeakers could be one of the very best on the market right now..

Seems unlikely. With rated sensitivity at 86dB, and impedance of 4 ohms, when you work out the math the efficiency is 83dB. That is a speaker that needs a lot of power to play anything unless in a very small room, and will suffer from thermal compression. To give you can idea of what I'm talking about, in my room I can reach 105dB without stressing the amplifier- at that level the system still sounds relaxed and smooth. My amps only make 60 watts but my speakers are 98dB 1 watt/1meter.

If I had those speakers in the same room to reach the same sound pressure level I would need an amplifier with about 2000 watts. Plain and simply, there really aren't any amps that make that kind of power and sound like real music. IMO these speakers are criminally inefficient unless you are unconcerned about playing most music at anything approaching realistic.
