A lot of this is going to depend on what speakers you have and what you expect out of them. I suppose you've already seen Steve Gutenberg's review of the Billie which is very positive (he keeps going crazy over the knobs!) but does much address the sound, which seems to be somewhat warm like a tube amp without being overly so. You can also play with tube switching for fun. Still, he says those looking for a more analytical sound might look elsewhere. Also, if you're a vinyl guy, the phono stage would be a consideration, which seems ok. Some question the headphone amp. Adequate power too, good warranty, and under $2000. That last thing is impressive. You're talking about the Spectral integrated at PSAudio which is like $3400. I got their prior model, refurbed, for $1745, no doubt when its former owner traded it in to get the new one which has a phono stage (I already had their old NPC phono, so a good deal for me). Now that combo runs a little more analytical. I think I would give the Billie a try were I doing it over again, especially if I didn't have the phono converter. There are a bunch of good integrated out there. Mainly find a good match for your speakers and be careful of that phono stage if that's your thing and the DAC if that is.
