Check out Sterophile's review of the Belleson Brilliance Phono Preamplifier! 

"Because it imposes so little of its own character on music, it allowed the character of each cartridge to shine through... If you are serious about playing records, and desire control over the parameters that mate a cartridge to a preamp just so, I recommend you check out the Belleson Brilliance. Brian Lowe has designed a modern, wireless-connected device that gives just about any cartridge a chance to sound great. Its mission seems in service of the cartridge: enable its best sound and then give it life through clean gain and accurate RIAA de-emphasis. That is no small task, and it was a pleasure to hear it done so well with such a wide variety of cartridges."
