I've been considering a JuicyMusic Peach preamp, has anyone heard this unit?
I have one presently and frankly love it. Sadly, I will probably have to sell it soon due to moving, but I'm trying to avoid that for as long as I can get away with keeping it. I originally bought it to prevent myself from spending time on DIY ventures. It is built very well, filled with nice parts, looks great, and does not sound overtly tubey or colored -- which I really like. Just natural, relaxed, and quite detailed.
I especially like the fact that it lets you run tube amps from the high impedance out, and can switch to the low impedance out for driving the occasional solid state amp. Both output options sound comparably good.
If you do consider one, let me know if you need any tube advice. Mullard 6922/E88CCs are my personal favorite by a good margin, but they might not be for everyone (a bit dry and bright). Tungsram and Siemens are quite nice too. I've had less luck with Amperex, due to either noise or dull sound. (Good sound = prone to noise, bad sound = dead quiet :sigh
There is also a new version coming out soon, which uses 6N30P instead of 6DJ8/6922 for the main gain stage.
