I'm looking to use my old CD player as a transport and add a DAC. The units I'm considering: Bel Canto, Perpetual Technologies P-1A/P-3A with power supply, or the MSB Platinum. Has anyone who's heard the Bel Canto and the PT units also heard the MSB Platinum? It's very difficult to find an opportunity to audition them all, especially side by side through the same system.
