ASR reviews are useless. I have a audiophile friend in town that swears by it, as one of the posters above stated they mostly review lower priced gear which there is absolutely nothing wrong other than stating its state of the art due to measurements which have no bearing on the sound quality that they produce. The whole system has an impact on what you get, I have a Benchmark Dac 2 HGC in my bedroom for headphones and when I put it in my main system I definitely feel the let down in sound quality compared to my Wells Audio Cipher Dac(tube). I have owned many good dacs over the years and have always went back to a tube based DAC. Ones to look for in your budget are the Wavelength DACS with the N2 board & ANK tube dacs factory built. I would have recommended my Wells Dac but I am respecting your budget of $2k.
My system is:
Herron 360 Reference ESP preamp
Herron VTPH-2a Phono Preamp
Sota Nova Turntable With Jelco 850 tonearm w/Haniwa HCTR-01 cartridge
Wells Audio Cipher Dac level 1 w/Bybee AC purifier's installed
432Evo Aeon Mkiii streamer
Miyajima OTL 2010 amplifiers(mono bloc)
hORNS Mummy speakers
Good Luck with your search.
