Can anyone comment on the Audio Mirror Pp1 Preamp?

Phd, yeah basically it was an independent job and a fairly Tuff job with such big caps… As for the 12Au7’s, if Mullards they are the most TUBE sounding tube I have heard, I have the 12at7’s which are a bit more forward sounding, but found the extra power of the 12at7’s necessary if running the MM stage from the Pp1.. If using MC the 12 aU7’s are super tube sounding(well mullards are)but would not suggest a cartridge much less than .4 mV, any lower you might need to go with aT7’s like the MM. The Stock AU7’s JJ tesla’s are okay too, but not super impressive. 12At7’s have more Punchy mid-bass sound, Au7’s have a more rumbling and room filling sound in the bass and are of course reduced power making the midrange sweeter and not as intense sounding as the 12at7’s. This will vary I am sure.

Can anyone suggest what type of cables to use with the Audio Mirror PP-1 ?

the chops

Thechops, any good quality interconnects should work well, I was using audio research cables and had some cardas cables on hand to try as well. You will need to experiment with different cables to get the sound you desire.

Anyway congrats on PP-1 preamp purchase, you'd be hard pressed to find a beeter sounding pre without spending an obscene amount of money.
