Esoteric K07 + Audio Research Dac 9 = Audio Research Cd 9


    In another post I asked about the required USB drivers for a Mac running El  Captian to a Cd 9. The response was that the CD 9 ( trade in from a dealer ) being sold to me ( currently still on home audition ) is a circa 2013 production unit which needs a Dac hardware upgrade costing almost $2000. No wonder I couldn't get it to work. Anyway, I still stream music half the time so the Dac upgrade is important to me and this unit is not being sold for a song either. So, it's either I purchase this one or return it.
     Now the problem, having the Cd 9 for the past 2 weeks ( still haven't returned it ) on audition I find my Esoteric unlistenable ( at least on redbook CD's). I prefer the overall presentation or "bloom" as other have called it on the Cd 9. I was willing to shell out the dough for a 2nd hand CD 9 but a new one is quite pricey at $13000.  But it is  only the circa 2017 units that will have the Dac that will be compatible with USB 2.0 or least with El Capitan. So a different 2nd hand unit is out of the question.
     My other concern aside from the price is that the Cd 9 has been out 4 years and will be due for an upgrade to maybe a cd 10 soon.
     Hence, the question above. Anybody tried it? I know it won't be the same but will it be close? My dealer does not have one on hand. It is by order only and no auditions. It will be a blind buy. But if it works out, I get to save almost half the cost plus I don't have to sell or trade in my Esoteric at a loss. 
     Inputs appreciated. Thanx.

Just to clarify, I was planning to use the Esoteric as a transport and use the Dac of the Dac 9 instead. 
lostbears,

    The Dac9 has 2 6h30 tube complements. So it's not solid state. I don't think ( pure speculation ) the Esoteric-Dac9 will be close either. Just hoping it might. 
    Thanx for the advice on the Singxer, I'll read up on that.
I did some experimentation and used a Line Magnetic 502 ca tube dac together with the Esoteric K07 as transport which  I totally forgot I had in in storage. Changed the stock tubes to some Pvane  12au7's. Did an A/B with a quick flip of the switch on  my LS 28 for about an hour or so.  The Cd 9 still sounds  more open,natural and airier but at least this combo tamed a bit of the edginess and forwardness of the K07, in my opinion. It's about 85% there, I think. I'll give it some more time. Hopefully, it's something I can live with.
I don't really need the DSD capability that the Dac 9 has to offer ( which the CD 9 does not have as well. ).
I  don't have the guts to spend that much on a cd player either and maybe I get to save some more with this combo ( versus the untested Esoteric- Dac 9 combo).  I could actually use the funds to finish my analog front end instead.
