Finally received my Lyr +.
Its built like a tank and very heavy which I like. I do not like how there are no balanced inputs or outputs but its not the end of the world as there is plenty of power in this amp to drive the LCD 4.
First impressions compared to the A90D:
Much warmer presentation and not as piercing in the treble. The bass hits harder and it has a more relaxed overall presentation that is very enjoyable. I would say the A90D presents small details better and the stereo imaging is also better on that amp however, I am only using the stock tube and I have more tubes on the way which should change the sound.
I ran the unit without any issues for quite a few hours and then I got a weird humming noise and I tried to locate the issue for maybe an hour to no avail. I have the unit plugged into my DAC which is then plugged directly via USB B to my gaming desktop PC. I found the issue and it was actually a game running in the background which created the humming noise. Closed the game and everything was as silent as a church mouse so I am glad I located that issue.
Overall, I am impressed by the build quality and sound of the unit and I hope that tube rolling will improve the sound even more so.
