Heat that penetrates through a blanket right to the skin sort of heat. Feels good.
So after all this stuff how does it sound?
A bit to my surprise -- very different from the Devialet.
SAM is of course out of the picture, but even when I would turn SAM off, they two amps sound quite a bit different.
The Devialet is inarguably more powerful at peak output, but looking at the VU meters on the Luxman, I end up listening to both at -20 dB, so they're both loafing. But the Luxman does sound better at lower volumes -- I'm not sure if it's because of the difference in distortion curve vs power output between the two amp topologies, the differences in the types of power supplies, or something else.
Phono stage is now fully analog, vs the DSP-based one of the Devialet. The Devialet phono stage is probably a bit more accurate, but the Luxman has better overloud margin by quite a bit -- and also more overload margin than the puffin. It's a pretty darn good phono stage, though, especially for one built-in.
The headphone jack is a bit of a mystery, though. With everything except my HE6SE, cans get plenty loud, but don't sound as tonally balanced as a separate headphone amp, probably because the output impedance is too high.
Despite the lowish-rated 85 dB sens and 4 ohm impedance of the Heritage Specials, giving them a reputation for being a bit hard to drive, the L-590AXII has no problem driving them in my medium sized room, possibly because the Luxman puts out amount of current.
The haptics are awesome -- the input relay switches go clicky when you change inputs or settings, the knobs go thunk, and the volume knob is like butter.
Having a record in / out, with a MONITOR switch is much better to use with a tape deck than the Devialet does. And the SEPARATION mode lets me integrate a DSP room correction device between pre- and power amps if I want to.
I could say more, but this is ASR and it's asking for a fight to get into audiophile creative writing.
