Nice simple tube preamp that only requires one tube, so you can try even the mostly exotic and costly tubes if wanted to hear the differences. Currently set for 12AT7 types, but a jumper can be moved to change to 6DJ8 types if that is your favorite. Great sounding black plate Tung-Sol installed presently. Multi-cap coupling caps for quick and clear sound for an uncolored view into what your tube delivers. In my opinion this is much better than similar preamps at this price range like the AR LS-1 in terms of sound quality with tighter bass and more extended highs. Not remote controlled. No obvious cosmetic flaws.
