dCS Bartok Apex vs any similar priced DAC

Several folks I know and myself drive ATC SCM50ASL(T) speakers directly with the Weiss DAC501. Most find the many DSP features useful. As far as I know, none of us are planning any further upgrades. One auditioned the T&A 200 and preferred the Weiss. Most folks out there that have made the comparison with Dave, prefer the Weiss.

If you are considering something as expensive as the Bartok Apex, also audition the new Weiss Helios which is in the same price range.

Honestly, if you're just running an ATC, I don't see why there's a need for a top flight DAC

Is the Esoteric N-05XD worth a look too ?

The matching Esoteric G-05 Master Clock Generator can be used as an upgrade later on. That combo should be a killer ?

Aries Cerat Helene, 40 Kg of sonic nirvana. I was only able to compare to non-Apex DCS. FWIW, DCS was very clinical and digital sounding. The AC Helene sounds like a $50K analog rig—two DACs at the opposite ends of the spectrum.
