I did try both preamps in my system for more than a week for each unit. Each preamp was coupled with a Soulution 710 amp, YG Anat Ref 2 Studios, a Meridian 808.2, and some other source units. I also tried out a number of other preamps, ss and tube, over the last several years. I ended up buying the Ayre KXR. While the Pass XP-30, in my opinion, did not do as well as the Ayre in my system -- I sit eighteen feet from the loudspeakers in an accoustically difficult room-- I have the highest praise for Mark of Reno HiFi. From a customer's point of view he is one of the very best dealers out there.
