Which used preamp for Halo A21, under $1,000?

Also, what are your thoughts on this reviewer's take on the CL's sound?

I am in St. Louis, I've had several established audiophiles sit in front of my system and have heard comment after comment about the transparency of my system... Cables made a difference, but can't comment on the reviewers experience. You would certainly be welcome to my home for an evening of listening.

Thanks for the generous offer Tim. Alas, I'm in NJ, otherwise I'd take you up on it.

So I've definitely narrowed it down to either the Coda CLX or the Wyred4Sound STP-SE. Anyone else have experience with the sound if either pre (or both) using the balanced connections with a solid state amp of the A21's ilk?

Update: I bought the Coda CLX. It was a dealer demo, so practically new and has the full warranty. I'll give my impressions once I have some time with it in my system.
