Strongly consider one of Professor Peppard's creations...I bought his Line 2A SE for $635, and it sounds awesome. I currently own the Eastern Electric Minimax, and an AES (Cary) DJH Signature, and the Mapletree Line 2A is way superior. Voices are so real its scary, and more than anything, this pre has brought emotion to the music...this is the first piece of gear that affected my listening so much that 'the hairs stood up on my neck' on many vocal recordings. I think its a beautiful design, but I am now more than ever convinced of the superiority of octal tubes in a pre. The amp can use either 12SN7s, or with the flip of a switch, 6SN7. I now believe that any 12SN7 is sonically superior to the best 6SN7's...I think its a much better tube, and they are cheap! I have numerous spendy 6SN7s that I tried, and the 12SN7 simply sounds better.
