@bluethinker You can take a look at system by clicking on my handle.
My power amp is a Pass Labs XA-25 (solid state). My speakers are very difficult to drive with a 0.5 Ohm draw in the high treble. The XA-25 is stable down to 0.5 Ohm, so this works well.
You should add your system so we can see the details.
I am new to the tube game. If I did not have the Bricasti M1S2 DAC I would consider the LTA DAC, but the M1S2 is so flexible I do not plan on changing.
