Preamp recommendations up to $2000

Just to give you some perspective on the Dodd, I've come to prefer it after having owned CAT, Lamm, Joule, Placette Active and Passive, Atma-sphere (which I prefer with my Atma amps) and a BENT Tap-X. I'm not saying you would like it better than any of these, though most would be out of the price range you are considering, but the Dodd certainly competes in this league. I especially like it with some NOS Amperex rolled in, the preamp essentially let's you hear the tube to some extent so it can be "voiced" to your preference - it doesn't sound at all badd with the JJ it comes with. As a former owner of the AI 3A, I can say that all of the above preamps were preferable to my ears - though for $800-1,200 it is a might fine sounding unit, just not in the same league with Dodd IMHO.

I second the deHavilland. There is a Mercury II for sale right now on Audiogon for $1995. If I didn't already own one, I'd buy it.

What is the input impedance of your Edge amp? Not sure about the output impedance of the other amps mentioned (AI was quite high if I remember correctly) but the Dodd is a 200 ohm output impedance (a very good thing for balanced sound across the bandwidth) single ended which about as low I've seen on a tube preamp and should be quite compatible with lowish input impedances found on most SS amps.

There a Modwright with Tube recitfier and upgraded caps for $1700 here. That's a excellent preamp for that $$
No association. I own a Modwright and a Supratek . They do sound different but one is not really better than the other.
One needs to be sold soon, but the market here is pretty bad and if you have the bucks nows the time to find some great deals.
