Too many choices for R2R DACS--opinions appreciated

Once again, thanks to all for the opinions and very helpful information. At this point (though it’s not set in stone--yet) I’m flipping back and forth between the Holo Audio Spring 3 KTE and the Sonnet Morpheus II. Reviews seem to favor the Holo DAC (narrowly), but there are downsides, principally the point of origin for shipping (Singapore, I think) and a rather long wait for the DAC to be assembled. There is a domestic source for the Morpheus which is a distinct upside, but it’s located here in California, so there’ll be a pretty steep sales tax tacked on. In the end, it’s probably a wash, price-wise. I did notice a Morpheus for sale at a pretty good price on USAM BTW, but you never seem to see Holo Spring 3 on the used sites. That could be a clue in itself. I’d welcome opinions. BTW, I’ve watched any number of Youtube vids about these DACS, which are pretty helpful but can’t really give a realistic idea of how one or the other would perform in my system (see original post).

Many thanks to everybody for the very helpful information, but now, of course, I'm faced with even more choices than I started with. I'll have to give some thought to the tubed DACs. My AMR DP-777 has tubes, but in general I haven't been (up to now anyway) a tube enthusiast. Some of the suggestions are significantly in excess of my budget, though. At this point, I'm leaning in the direction of Denafrips, and possibly Sonnet. I'm still open to further suggestions and opinions. 

Oh, and meant to mention: I don't really need the DAC to include a preamp, though many do. Just need it to do what it's designed to do, namely convert digital to analog. 

Has anybody heard the Jay's Audio DAC2-MK3 yet? There is scant information about it so far, and I'd be interested to hear some firsthand experiences. There's one for sale here on Audiogon at a rather tempting price. 

O.P. weighing in again here: you guys realize you’re only making my life harder, right? There sure a lot of great choices out there. I’ve added the Holo Spring 3 to the list now. Decisions, decisions...

It appears that most of the ones I’m interested don't reside in dealer showrooms, so at some point (soon) I'll have to figure out which one is going to work best for me and take the plunge.

The Holo May, wonderful though it seems to be, is simply out of price-range for me. I suppose if I wait some time (possibly a couple years) it'll come down, but for now, I need to concentrate on the $3K range, where the Spring 3 and the Morpheus live. It's kind of difficult to sort through all the reviews, and some of the videos on Youtube can be a bit of a slog to get through, though the information is extremely useful, once you get there. I found this one (it's LOOOONG) very helpful, but you sort of have to tease out the relevant parts:

It was a big help in my decision to drop the Denafrips Venus II from my list, and in reinforcing my preference for the Sonnet Morpheus. I'm kind of leaning in that direction right now, but haven't totally committed. Stay tuned--I'm nearly there...

Update: I've pulled the trigger (finally) on a Sonnet Morpheus which I found on another site for a very attractive price. It should be arriving in a couple of days (the seller is pretty close to here), and I'll share my impressions of it once its up and running. I had a choice from different sellers for either USB or I2S over ethernet cable and I've opted for the version with USB which will be more immediately useful, as I don't have any I2S sources (yet...). Someday I might add a network streamer to the mix, but that's a future project.

The Morpheus arrived on Friday, and it’s been going through its paces all weekend. I’m informed by the seller that it’s had plenty of time in his system to reach its full voice, so I assume that’s what I’m hearing.

Initial impressions: everything they say about the imaging and detail retrieval is true. Spatial cues are vastly improved over my previous DAC, and while the higher frequencies are brought a bit more forward, the Morpheus maintains solid control of them, so they never sound shrill or glassy (unless the source material sounds that way). Voices, in particular, sound natural. Bass frequencies are also very present and well defined. These qualities are very impressive.

However (and yes, there’s a BUT here), there’s a tradeoff for all of this compared to my AMR DP-777, and that is the fullness and roundness of the musical events. While the Morpheus is certainly not what I’d call analytical, there’s a relative thinness to the notes, as if the music has been slightly deflated and spread. That’s where the AMR DAC exceeds the Morpheus: in presenting the image as a unified event. It’s not as precise in its presentation as the Morpheus, but to my ear, it’s more appealing.

So all things considered, I’m impressed but not exactly in love. I guess unless I’m willing to spend some really big bucks, there’ll always be some sort of tradeoff. I’ll live with the Morpheus for a good while and see if my tastes/ears adjust to this new soundscape.

Thanks for the suggestions about inputs. I've been mulling over the prospect of adding a streamer to the system, and I wonder if anybody has compared the Metrum Ambre with the Sonnet Hermes? I'm still limited by my choice of USB over I2S configuration on the Morpheus. I may have made a wrong decision here...

Update (yet again): the Morpheus has been doing its thing in my system for about 12 days now, and an interesting thing has happened. Either it has opened up some after quite a few hours of run-time, or my ears and sensibilities have accustomed themselves to the way it presents the sound, or possibly a combination of both. Since it wasn't new when I bought it, I assumed it had been entirely burned in, but maybe not entirely. In any case, I'm really starting to love what I'm hearing now. The slight flatness I was hearing before has resolved itself into smoothness, and I don't find myself pining for the slightly rounder-but-less-precise sound of the AMR DAC that the Morpheus replaced. Had to do a bit of experimentation with inputs, as previously I had been running both the TV sound and my Cambridge Audio disc spinner through a Wyred4Sound Remedy Reclocker which converts everything to 24/96 resolution. It's a big help with TV sound which can only be connected through optical cable, but I found that the disc spinner sounded far more natural and appealing connected directly to the DAC via coax (I'd love to try AES/EBU, but the CA spinner doesn't offer that connection) and playing CDs at their native 16/44.1 resolution. 

So I think the Sonnet Morpheus is going to keep its place in my system for a good long while. Falling in love with it was a slow process, but I'm there now. If I get itchy for further upgrade, I have a pretty good sense of which direction to go, but that won't be soon. 

Thanks again to all for the helpful comments and information.
