BAT VK-31SE tube preamp. Outstanding preamp from BAT, using 6H30 super tubes. Balanced and single ended inputs and outputs. Quiet, very transparent, smooth, and extended at the frequency extremes. VERY dynamic with great PRAT. Many prefer this to the current VK-32SE. Just an outstanding pre from BAT. Once you go BAT, you won't go back! Selling only because I have gone pre-less with a DAC that has a volume control and I only have one source. Priced well below Agon Bluebook value. Local pickup is welcome. Paypal adds 3%.
