I just purchased a lightly used MSB UMT V Signature Transport with two power bases. It is built like a tank. The transport has a solid aluminum tray and is based on the Oppo BDP-105D. The two power bases are really heavy. They feel like solid blocks of aluminum.
I think the sound quality of my Select II DAC with Renderer V2 Module and Roon Nucleus Plus is terrific but the asynchronous transport with its proprietary Pro I2S connection surpasses it in transparency, ease and noise floor. Stunning vocals and instrumentals emanate from dead silence. The noise floor isn’t quite as low as MSB’s new Pro ISL optical connection but having listened to this transport and the new Reference Transport, I can tell you that sonically, it is damn close. The Pro ISL optical connection really excels when used with the Pro USB Module for computer audio, where electrical noise is much more of an issue than on the transport.
Consequently, I am very happy with this purchase as I can now spin CDs and SACDs again, and have improved sound quality for a fraction of the price of the Reference Transport.
