The Stan Warren Modified MSB. I have taken this DAC around to various high end dealers, and it has beaten EVERY one in terms of musicality, dynamics and holographic imaging. Best of all, it is much less than $5000. (Stan Warren has some customers that can afford $10,000.+ DAC's, but they, like myself, are astonished at what he can do with many digital platforms...He will have you embarassing your other audiophile buddies'"break the bank" electronics!)
