We're partially tempted to simply say nothing. For those who know, the SP-2B speaks for itself. For those who don't, let's just say that Brown Audio Labs should be regarded as one of the most important boutique manufacturers today. Yeah, we know it's not vintage, but it's tube. And it's damn cool.

- Liner Notes
- Absolute Sound magazine reviewer Dick Olsher, had this to say about the 2B's predecessor, the SP-1B: “After 30 years of audio reviewing, I’m not often surprised, but the SP-1B’s phono input performance definitely did the trick—it put on a show. And it did so to an extent that qualifies as a “wow” moment in my book. In the case of the SP-1B, it destroyed my expectations of what was sonically possible for an affordable preamp. First and lasting impressions were of spectacular dynamics, suave midrange textures, and excellent low-level resolution.”
