Sorry, Lyr is gone. Maybe the Lyr sounds better as a pre-amp to a power amp but as a pre-amp to active monitors it is not the way to go. Eventually I found the Swans to be better without the Lyr as a pre-amp but maybe you can play around with your source levels to get the least static from your Swans.
"As quiet as the Lyr was on headphones, it now exhibited PSU noise. Its already high output signal was further amplified by a completely unattenuated Ampino (volume control fully opened to be bypassed). Lyr noise disappeared when the amp's control was closed by half to sit at 12:00. Given that the Lyr's core equation of 50:50 valve/transistor aspects was shifted to get sandier by 75% if not more, it was reasonable to expect lesser 'tube goodness' enhancements. And so it was. Very much to its credit if neutrality was a core design consideration, lyrification of the signal path produced only modest differences. Bass mass and heft built out, overall weightiness increased. On the flip side transparency, subjective speed, separation of tight weaves and transient sharpness diminished. Both flip and flop were surprisingly mellow, give and take balanced to not make this a clear-cut step upward but more a lateral move into a different flavor."
