There is a statement in there that the LISST definitely warm/heat up, but not as much as tubes. So, a couple things could be happening:

1. The LISST is regulating down the tube high voltage (i.e. 200+ volts) to a more solid state level such as 15-30 volts and generating heat as a byproduct.

2. The LISST MOSFET circuit is running in Class A mode, which generates more heat.

Or it could be both of these. Schiit indicates the LISST are MOSFET circuits, as oppose to JFET that is the solid-state circuit in the Freya. So, it's really difficult to tell if the LISST is going to be any different than the built-in JFET.

Honestly, I think the JFET mode sounds somewhat flat and sterile when compared to good tubes (the Schiit stock tubes are not included). You could always try the LISST, but at $99 a pair, it's an experiment that may or may not be better than stock JFET.

If it were me, I would be going after the PSVANE CV181-TII, even though they are a lot more expensive.
I'll have to try some of the PSVANE CV181-TII tubes so as to get a better listen to what the tube stage is capable of. Schiit says that the LISST units "measure better" than do tubes - but we all know what that's worth.....

Hey SoundMig,

I just got back from visiting a friend. He ordered a set of PSVANE 12au7 tubes and I helped him install those in his tube preamp. The original tubes were JJ, which we pretty good. After just a few hours of burn-in the PSVANE were very excellent. They had much better resolution and definitely made that preamp "sing". There was none of that "tube color" such as added texture / liquid / chime. It was almost approaching solid-state, but with soul. So, I highly recommend the PSVANE.
