    Great read thanks for the link I'm going to add one of these to my rack. But first things first I need to get rid of my **** child Xpa-5 I think these sell quick on the used market hopefully.

    Well I bought the amp today after doing some research I think this is the path I want to take. After doing some research it appears it is a Nelson Pass clone not an exact clone but the design philosophy is from a Threshold design of yesteryear. Not an exact copy as N.Pass stated but none the less the philosophy for the design was from the man himself it appears.

    Nelson Pass:
    The Usher has a different front end - it is biased by different current sources
    and uses current mirrors off the input stage and has a differential VAS. The
    first does not regulate as well, and the last two create a higher open loop
    gain (for more feedback). The bias system is different and is placed after
    the drive stage, not before.

    The output stage is pretty similar though.

    And yes I did buy it on audiogon seemed like a great price and appears to be in perfect shape as well.

    I really liked the Usher pre-amp when I had it and figure the amplifier would be equally pleasing. That's a very nice setup Montoya :D
    CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.
