Bobby, if someone were stupid enough to experiment with a passive preamp (me), would you expect the BAM to perform best between Source and Passive, or between passive and Amp. There is no issue of amp sensitivity, amp input impedance, or, with short Cardas GR, cable capacitance. I'll still have the Joule LA150 MKII Signature, and the Atma-sphere MP3, so I haven't gone native.
