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?

"Roger can now operate it as he deems best. For example, he can now offer lifetime warranties"

Doesn't the warranty expire when Roger decides to call it quits? Is there a long term plan in place for that?
Jtwrace, the same question can be asked of any small volume electronics manufacturer in high end audio.

If you are concerned about having a reliable long term warranty and don't mind the sound of harsh PA amplifiers, just buy a Bryston.
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.
