I received my Lyr+ (along with a Bifrost 2/64) today, shipped after a three week wait, and so far everything is working fine (knock wood).
I've substituted it for my Asgard 3, leaving in my Bifrost MB (1 with Unison) to institute only one change at a time and in order to be able to compare it to the Asgard.
Initial impressions are that the Lyr+ (in SS mode, I haven't inserted a tube yet) is more transparent, more evenly balanced frequency wise, more tonally accurate, and possessed of better image separation. The only downside so far - and of course, this is with only a few hours of playing time - is a bit of lack of weight and a "slipperiness" to the upper midrange/treble. Hopefully these deficits will disappear with more use, or at least in tube mode.
