Sanders sound or parasound for big ESL's


Just wondering what you thought about either a pair of used JC-1 monoblocks to run big ESL's or a used Sanders/innersound amp. The JC-1-s can be had for around $3500 used, not sure about the sanders or innersounds.

I realize the Sanders has some pretty significant upgrades over the innersound and don't mean to start a Sanders vs. Innersound war. Both designed by the same person with the Sanders upgraded internally (the list is on his website). The Sanders gear isn't available used, or hardly ever because there just isn't that many units out there. Innersounds are easier to come by.

If anyone has had experience with either or both let me know. They would be used to drive A-1 Soundlabs. I don't have a preamp yet so I can match it to whatever amps I purchase.

Thanks in advance

I thought the JC-1's might be a finer amplifier but for the money your right, it's tough to argue the Innersound value. The JC-1's are around $3500 used, over $2000 more than the innersound. There may not be a $2000 difference to be heard, though it would be great to compare them side by side. Thanks for the input.
Mike,

Thank you for your educated response. I have read every available review on the innersound amp and continue to be suprised at how well it's covered. Very neutral, loads of power and stable throughout the vastly-ranging load the SL's produce. For the money I believe I will look for a used ESL300 for the time being. The JC-1's I believe are a step up but I am not finished with the system yet so that may be an upgrade in the future. As you say, most of these amps have hit bottom or close to it considering depreciation. Thanks again for everything!

Cofeey,

Innersound is no joke. This is the product of Sanders who is now of Sanders Sound. He is well known for pioneering amps specifically designed for low impedences and high resistance. From everything I have read here on Agon from owners on the forums and reviews on line the amp was a deal at $3K new. At close to a grand used it's down right a steal.

My speakers will drop most amps on the market to their knees with very little audible volume produced. There are a handfull of amps out there that will do a great job at running the big Soundlabs, the innersound amp is one of them. And I am not aware of anything even close in the thousand dollar range. If you have some ideas I am all ears.
Coffeey,

No need for apology. I understand your meaning now. No worries.

Ejlif,

I am surprised you clipped the 300's easily. Your Eros speakers must be quite a load or possibly your amp was running at less-than-optimal condition? Can the ESL 300 be run as a monoblock? I know sanders now makes his new amp as a mono but I thought if the ESL 300 didn't have quite the umph to push them a pair might do the trick.
Tpsonic,

That begs the question. How much did the conversion cost and did you feel it made a significant difference in performance? Two 300ESL's at approximately $1200 each is $2400 plus the conversion and shipping may be pushing $3K. At that price point it's getting close to JC-1 or Spectron range. I wonder how the mono'd 300ESL's would do up against a pair of JC-1's. That would be an interesting side by side.

A safe way to go might be to try a 300ESL alone first. If it can't push the load, another could be added. I saw a pair of i750's for sale recently but they were around $3.5K each.
