I'll second the Sonic Frontiers Line 1. This will integrate easily into a home theater set-up and then serve as an outstanding 2 channel preamp. The line 1 gets alot of negative reviews from some, but only because it's so neutral. Some were looking for that tube warmth and with the stock tubes, it wasn't a warm preamp, it didn't add any colorations of its own. It my mind, it was overlooked because of this, but with different varities of NOS tubes, it's a totally different preamp. You actually get the best of both worlds with the Line 1. If you want warmth, changes tubes, if your ears lean toward neutral, leave the stock tubes in. The Line 1 has so many features, and with the used prices it's selling for, IMHO, it's a steal. Goof luck.
