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).

 @mzkmxcv I didn't mean it measured as good as the benchmark but for the price it was a good deal for something less expensive.
Brand new Chord Qutest for $1500 will simply blow any of the above DACs entirely out of the water. See the latest Stereophile review.

I'll go as far as saying that Chord Mojo with a 3.5mm to RCA cable equals Mytek Brooklyn or Benchmark DAC3 in every area at $500 and bests them in quite a few. I've played with them all and currently own the Mojo, Hugo 2 and Dave in my three systems.
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!
