Pass Labs X250

[E-Stat]

I am astounded at how good this amp sounds.

I've been of that opinion since I heard Nelson Pass' first amp, the Threshold 800A back in '75.

If I have to list the con's to this amp, they would be that it gets hot while my A21 almost never got warm.

All his designs are amply biased. All one needs to do is look at the massive heat sinks found on virtually all Threshold/Pass Labs/First Watt models. My '81 Stasis also runs quite toasty.
