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?

I have the Sanders Slim Linestage preamp and the Magtech amp. My Slim Linestage and Magtech combo is the best sound I have ever had. I previously had the McIntosh C220 preamp and the Parasound JC-2. IMHO, you will never be sorry with this combo. I am driving a pair of Duntech Sovereigns (big, big speakers) and I am in Audio Heaven. Happy listening.
I had an Innersound iPre several years ago to go with my Innersound ESL300. I found the iPre to be extremely transparent, but would also describe it as sterile and uninvolving. Music just didn't sound that captivating played through it.

I've since moved on to other SS and tube pre's, and I'm much happier.

Just my 2 cents.

Isn't Sanders and Innersound the same? Did Sanders buy Innersound or something?
