Laid back DAC under $800?

A lot of excellent advice here.  I'll check out multibit ladder from Schit. Good point about changing out the tubes in the Black Ice.  Not a lot of reviews about it though.  Wonder how it is with features and ease of use.  The D70 is really nice in that department.

+1 on the Schiit product line.

Bifrost vs. Black Ice?  

Haven't seen a Metrum or Bel Canto. 

I think above you said you had an equalizer?  If you want a simple way to use it, try boosting each individual frequency until the objectionable tone pops out at you. You'll know it when you hear it.  Then leave the rest flat and cut back a drop on the offensive one. Maybe it will solve your problems.  

There's an equalizer in Roon but not Audirvana. I think Foobar might have one.  I'll check.  Still will likely upgrade because.......that's what happens. Lol.
