The Bryston BP-2 MM/MC Phono Preamplifier may be a one-trick pony that simply accepts analog audio from your turntable's cartridge and amplifies it to a level that your main preamplifier can understand.
Phono gain stages are rather un-glamorous. But that's the point. What makes the BP-2 so special is that it can take such a minuscule signal--2mV or so and amplify it with so little distortion and so little added noise. When switched into MC mode, zero additional noise is added. The transformers are wound so precisely, they are virtually distortion-free making the most of your priceless MC cartridge. This is true analog bliss.
