Sanders Sound preamp vs. Innersound?


I just recently picked up a Sanders Magtech amp to drive my new Maggie 1.7s and I am now searching for a preamp to join the party.
I was originally thinking I wanted to go with a tubed pre:
Modwright, SWL 9.0 sig., or new LS100.
Cary SPL-98
ARC, LS17 or LS25.

I just noticed 2 ads for a couple of Innersound preamps here on AGon that look very attractive.
The Innersound pre would be the perfect (solid state) match but I am guessing it would be much more of a neutral sounding pre, than any of the tubes units I am considering?

I think from neutral to warmer, these would ranked as:
1: Innersound.
2: ARC.
3: Modwright.
4: Cary.

Does anybody have any experience with the sound of any of these brands and if so, how would you compare the Innersound / Sanders to them?

How does the Innersound compare to Roger's current Sanders preamplifier, I know they look pretty much the same but how much has he done to improve it?

Actually THAT question should only be asked of companies that offer a lifetime warranty. After all, lifetime is a very indefinite term. It could effectively turn out to be only 60 days.
Well, I can answer the question probably as good as anyone. I purchased the full Innersound system (speakers, amps, crossover/amp, phonostage and preamp) in November 2001 (and have just upraded the panels for such a rediculously low price, I am still amazed). They sound incredible. Roger has been there with me EVERY step of the way WHENEVER I needed him, call it Innersound, Innersound LLC, Innersound abc or Sanders Sound. You deal with Roger, you get him, his support and the best products on earth. I am incredibly fortunate to have had him recommended to me years ago. I could never think of changing my speakers, amps and preamp. (Maybe Sanders amps but that would be it).
I see a SandersSound thread, and have to put in my .02. Not only are his products great, but Roger is a fine person to deal with. I owned one of his of his ESL amps (driving Quad ESL 63's), and was just curious about certain design aspects of the amp (no problems, really just curious). Roger and I spoke by phone at length and then he followed up by email. What a nice, nice man to deal with. This is probably 4 or 5 years ago already but Roger left an indelible impression on me.
Rogers goal is to provide state of the art sound at a reasonable price. What he really does is provide state of the art products that just get out of the way of the sound, at affordable prices.

He has succeeded.
