Innersound Electrostatic amp driving Quad esl 57's

For decades I have heard and read that you don't need more than 25 wpc. With that being said, there is apparantly circuitry built into this amp that enables the user to realize the benefits of much greater power without damaging the quads.

Rmarcus5757, do you mean to say the InnerSound amp has a "Power Limiter" that limits the power of this 600 watt amp to around 50 watts/channel just for Quads? Hmmm, that's the first I've heard of this! Maybe the channels are fused and you can change fuses to accommodate any speakers?

Regardless of that, it may not be the best sounding amp you could use on the Quads...

Thanks again - I like my Bedini's but am open to suggestions regarding amplification.

I had several amps driving ESL57's over the years including a Bedini 25/25. The best two that I heard were the Levinson ML2 (no suprise) and a Naim 250 with the output reduced internally. I tried a Marantz 8B, Dynaco St70 and MkIV's,Berning EA230 QuadsII, and 303. Make sure you have the protection boards installed and good luck.

The danger with the '57 is arcing damage due to too much power, hence the 25 watt thing.

But they are also very tube friendly (in fact were designed for tubes), and will make bass with a tube amp that they will not with transistors. If I were you I would consider tubes on that account. Its a classic combination.
