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).

Think front row with Benchmark or Mytek. Think row 8 or 10 with Chord and PS Audio. All four DACs are good and have their loyal followers.
I can't speak to your current dac but I use the Holo Audio Spring Level 3 dac and it sounds very organic to me. I'm very pleased with it. I have also heard good things about the Denafrips dacs. Each are R2R designs.
Problem with detailed focus digital:

I did the CDP climb about 15 years ago, each step up more details were revealed in recording. At the time I thought I was moving into better but what I learned and became aware of later was the number of CDs in my collection that were enjoyable was reduced and the types of music I enjoyed got more narrow. There is a reason artists and music like Diana Krall became so popular over this time period. Loved Led Zep as a kid, thought maybe I grew out of them when I listened to them on CD, spinning them on vinyl was a point of awareness of what improving digital did to the recordings. I learned at demos to bring my worst sounding CD that I enjoyed to not just the nice sounding CDs.

I moved deeper into vinyl, sold off my expensive CDP and invested in a better TT setup. As I upgraded all vinyl recording improved each step. 
Settled on the Rega DAC R for digital and was impressed how well it framed every kind of music and I was back to buying CDs again. Now I'm itching to improve my digital hoping there is a better DAC that frames the music in a way that doesn't reduce what I enjoy or narrows the type of music I listen to. Digital has changed so much, the R2R design looks interesting and in general how it's marketed seems to be in line with my focus. My concerns are how some of them measure and most come out of China which could be an issue for service or repair in the future.
I'm a Benchmark believer.  Their products keep replacing existing products in my system.. I suppose if one's speakers are harsh or bright, the Benchmark products may sound harsh or bright, but with accurate speakers, you get addicted to faithful, low distortion sound provided by extremely well-engineered Benchmark gear.  I wonder if their new HPA4 linestage/headphone hints at a DAC4 companion piece? i.e. 4<-->4.
