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 know nothing of anything new coming from Roger, but up to at least very recentyly, he paid Coda for their technology and built his own goods using Coda boards and chassis. If you call Doug Dale at Coda, he will give you age and model comparisons based on the Coda board in the Sanders or Innersound products that you are looking at.
The current Coda stuff is very good indeed, it is worth the phone call as Coda sells manufacturer direct only in the US.
Check out my Coda Windows 4 ad. Sorry to bother here I couldn't figure how to do a direct message.
So Sanders newish Magtech amplifier is a Coda design but using his own linear voltage regulator power supply?
Soundlock, I'm becomming very interested in the Magtech. What amplifiers have you owned in the past?
