High Current Monoblocks

I used NuForce REF 9 V2 SE's with an ARC LS26 with outstanding results. They have plenty of muscle for my very demanding Aerial 10T's and are as transparent an amp as I've ever heard, by a wide margin. I would give them an audition.

More practical implication of high current amp is that they can deliver needed power in difficult lower impedance load. Ohm's law says when the load impedance goes down by 1/2 (say from 8 Ohm to 4 Ohm), it requires twice as much current in order to maintain the same voltage. High current amp will be able to maintain the voltage when the impedance drops to 4/2 Ohms, thus "double down" on the power. Current limited amps will supply constant the amount of current in 8/4/2 Ohm load, thus the power supplied will decrease as the impedance drops.

I'm in agreement that you should seriously consider the Sander's ESL or Magtech monoblocks. They're ridiculously powerful, relatively small and light, put off very little heat, have a ton of amps behind them and almost zero distortion. If you haven't looked into them by now, you really should. I have his ESL amp and it's an absolute dream! Transparent, neutral, and smoothe, with a punch that you wouldn't expect from such a light component. They drive my Martin Logan Summits like they're nothing, and those badboys can dip down to 1ohm.

Power to spare, great sounding, and absolutely bulletproof. On top of that, Roger Sanders gives his equipment a lifetime guarantee and he's a super cool guy that will work with you PERSONALLY. How many big-name manufacturers can you say that about?

Good luck and happy listening!!

Punishen1, I have no need for more than 900 watts per channel into 4 ohms, but the Magtech is outstanding. I also have never compared it with the ESL. Since that amp is primarily for electrostats, I would expect the Magtech would be better suited for other drivers, as Sanders doe say.

You omit another strong reason to buy the Sanders, it is inexpensive and a true quality product.

Also Sanders warns that you may need a 240 volt supply for the monoblocks into lower impedances.
