Amp/ preamp for electostatics and why

Solid state amplifiers always sounded lean on my Martin Logan CLS, but any tube amplifier sounded great. After trying numerous solid state amplifiers I decided the problem was the speaker's wicked impedance curve.
The CLS has very low impedance in the upper fequencies and when solid state amplifiers see a low impedance, what do they do? They produce more power. Also, the CLS has very high impedance in the low frequencies where the solid state amplifiers would produce less power.
More power to high frequencies and less power to low frequencies made for a very lean sound.
Tube amplifiers didn't seem to care providing the wattage was high enough.

I own Innersound stats powered by a ss/tube hybrid used in combination with an Audio Horizons tube pre amp.I've lived with multiple ss amps and have not been able to capture the magic of my current set up.There's just a natural synergy with appropriate tube amplification and Electrostats.

I would love to have a tube amp but there are two problems.One, I don't know how to bias a tube amp and;Two, I prefer monoblocks and good high powerered tube monoblocks are expensive.

A good used pair of 100 watt tube monos to drive your SL3s will cost you $800-$1200. For that price you can buy VTL Compact 100s or Quicksilver Silver 90s. I have used both with Electrostic speakers with good results.

100 watt tube monos are very powerful and you can easily learn how to bias them.

I have one other thing I would need and that is balanced connections. Anybody know of a 80+ watt tube monoblock with balanced connections?
