Eggleston Andra power requirements

I failed to mention prior to the pair of MC275's, I tried pushing the Andra's with 75 tube watts -- big difference when I went with the dual 275's -- just what the Andra's were looking for.

My friend could not drive them properly with antique soundlab monsoon monoblocks. Thick, slow, bloomy sound, for some musical, for some boring. He thought boring. Now he drives them with Spectron musician monoblocks. Now he is on the other side of the pendulum: fast energetic but cold and tipped up sound. We recently tried with nuforce monoblocks (plus PS powerplant and top of the line Harmonic technology cabling). That configuration seemed to be a balanced way between the two extremes.

What does the Mc2301 add aside from more bass? (Comparing to two 275s)

Thanks

One of my friends has the Andra I's. He is running them with the FPB 600 Krell. It has good control over the bass.

Perhaps it goes without saying, but if not, here goes: These speakers have low impedance (approximately, and probably less than, 4 ohms) at low frequencies. I would recommend amps that have 2X the output at 4 ohms as they have at 8 ohms. As for tube amps that do that, there may be plenty but I got nuthin'.
