RE: A lot has to do with the ESL!
Posted by Ralph on April 10, 2017 at 08:41:53:
ESLs can be quite tricky for solid state!
The reason is they have a high impedance at low frequencies and a low impedance at high frequencies.
Solid state already tends to sound bright; when you combine that with the inability to make power in the bass region, the result is a system that is bright and the amp not making anywhere near the power it should be (and likely not enough bass impact).
This is why a 140 watt OTL can keep up with a 600 watt solid state amp on Sound Labs, and actually play better bass.
