Your list is a good one overall IMHO. I'm about to sell my full service Quick pre (have a strong potential buyer at least) and I've loved it. IMO, it actually betters the new remote one if it's in good shape still. I may look for one of those used on the site as they are less than the new one. Have you heard the AI yet? If not, you need to. Forget reviews and just put it in the system and listen. The thing with tubed preamps is that many of them dont' match well with your SS amp. You really need to listen to them together to see if they can match. I've seen too many folks get a great pre and a great amp, but they don't match at all. You probably already know that, but some folks don't, so I thought I'd throw that out there.
