Which DAC: Benchmark, Mytek, Audio Mirror, Holo Audio, Mojo Audio?


Looking to upgrade my current Rega DAC-R and have been doing some internet searching and these DACs look interesting and fit within my price range:
BENCHMARK - DAC3 B - $1700
MYTEK DIGITAL Mytek - Liberty DAC - $1000

Audio Mirror - TUBADOUR III DAC - $1200
Holo Audio – Spring DAC 2/3 - $1900-2700
Mojo Audio - Mystique v2 SE DAC - $2500
The other option is to just stick with the Rega DAC-R
I play CDs only and would like to maximize that format. Anyone have experience with these DACs? I have no opportunity to audition them where I live.

Which DAC would provide the most significant upgrade from the Rega? The Rega frames the music well and sounds good with almost every disc I throw at it. I’m not shooting for different and I don’t want something that will limit what's  enjoyable (CDs or types of music).

Also, best part about Chord DACs is that you can stream with a $39 Google Chrome dongle and you can't tell a difference between that and $5000 streamer. They are simply not jitter sensitive at all.

If you are a music lover, as opposed to an audiofool with only 5 CDs which includes 3 Patricia Barber albums, then please read the reviews of the iFi Pro iDSD DAC on the web. I don't understand why @audiotroy did not recommend it as an AMR dealer.
I recently sold my transport (PSA PWT) and dac (Digital Amplifier Co. DAC) which sounded fantastic, to a one box Sparkler S503 CDP. Since I haven't embraced computer audio, and still spin the silver disc the S503 was a no brainer! Small in size, big on sound quality, and will cost you less than a trans-dac front end!

The Chord Qutest was actually on top of my list until I started digging deeper into some of the discussions. Some people were making claims that it was sterile and analytical. I don't believe everything I read but there seems to be a lot of spamming with the Chord and Schiit DACs on the net. The sterile and analytical complaints of modern DACs lead me down the R2R path which sounds more interesting but they seem to be coming from overseas companies and some have had issues with measurements.
