I saw the curve somewhere online recently. It was flat save for a fairly narrow peak in the middle of the audio band. I'll see if I can dig it up.

Anybody know what Brian is up to these days?

I looked but was unable to find anything.

A pair of MA-2s drove Brian Walsh's pair rather nicely although he tended to clip them. :)

  It must have been pretty loud!

    I get comfortably loud with 300 vs 220 watts on mine, but really need double that for (merely seconds of) pieces like Rite of Spring .

      Then its likely on a Sound Lab its not as much power as you think, due to the impedance curve at low frequencies.
      
      So as a general rule of thumb, divide by 4 to get the solid state power on them. So if you have a 400 Watt (into 8 Ohms) solid state amp, its able to make about 100 Watts on this account.
      
      So (IME) you really need a 600-800 Watt solid state amp to make the Sound Labs really fly.

        Exactly. The reason an OTL amp is a very good match with electrostats.

        Someone else mentioned your recent absence.
        
        There is a page for Dr. McCollum over at planar about a concern over 63 vs 57 panels. :)

        Which shouldn't be a budgetary problem for those with $60k speakers. :)
        Nearly twenty years ago, first gen JC-1 amps did just fine with M945s at a meeting in Chicago. Current version has more mojo!
