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).

I bought an original Mytek Brooklyn and really like it. Dynamic, a lot of detail and never strident or harsh. But...I still prefer my Mhdt Havana. I just keep wanting to listen to music with it.
Seconding the Holo Spring Kitsune Level 3. It's quite amazing, with highly compressed through hires music all sounding great. I think the second most important component in my system (after the speakers - Goldenear Triton Ones).
Unfortunately it's tough to get to listen to the Kitsune as they don't do loaners and there is a long wait to get them...
For me, the Crane Song Solaris combines the best of ultra-transparent pro DACs like Benchmark and Mytek with (for want of a better term) the "richer" sound of many audiophile DACs. With the possible exception of the Benchmark LA4, I haven't yet found a preamp that does not in some small way degrade its sound. 
As regards ladder DACs, I've only had one experience which does not inspire me to try again. I had an MSB Diamond DAC IV+, maxed out with all the options except the network renderer which only became available after I sold it. Now this DAC, with its matching Diamond power supply, retailed for around US$40K. After I purchased it, it was tested, serviced and recalibrated not once, but twice, at the MSB factory. Whether direct-to-amp, as MSB recommends, or via a preamp (Boulder 1012, VTL TL-7.5), it had exceptional bass, but rolled off highs and a nothing-special soundstage. It never drew me into long listening sessions, unlike the same system with any number of (by comparison) budget DACs: MyTek Brooklyn with Mojo Audio power supply, MyTek Manhattan II, Universal Audio 2192, Antelope Audio Pure 2, Crane Song Solaris (among others).
