Recommend me a DAC under 3k

It looks like your Wiim Pro Plus, has coax and optical digital outputs.....so no need for a DDC right now. You may want to consider the DAC input options, if you plan to upgrade the Wiim in the future.....one that does have USB outputs.

+1 for R2R ladder DACs, but I'd also throw in the Weiss DACs. The 205 ($2,600) which does not have USB input, or the more expensive 204 ($3,500) which does add USB input. I can also highly recommend the Musician Aquarius ($3,100) and the Denafrips Pontus II 12th ($1,850) , both of which I have extensively tested in my system. I own the Denafrips Pontus, but the Aquarius takes things to another level....albeit for an additional $1,300.

Personally I preferred the Denafrips Pontus and the Musician Aquarius over the Denafrips Venus, but if you are looking for a more detailed presentation....the Venus just might be right for you.

Even Jason suggests the Bifrost 2/64 is a match for the Iggy. 

Do not overlook less expensive units. Of everything I have had in my system, my cheap JDS Atom+ has been the best overall.  ( $99)  I too am looking at the Enyo (Aries with new price) Mojo II, Qutest, or maybe a newer top line Delta Sigma like the SMSL DO300, Topping, Gustard X18 etc. 

My focus is 90% on female vocal smoothness. Don't care about bass "
weight" or some magical details in imaging and air that were not on the recording to start with. I focus on what I do hear reliably. There are a lot of expansive DACs, but are they really better than what you get for $1600?  "$700? or even $99?  Do we want "clean" or the masking from an R2R? Masking from a tube?  ( Or do we want that masking to be in a preamp?   Lots of choices. 

Upgrade the power cord. Yea, a 49 cent ferrite on the cord and it is as good as physics allows it, if and only if you have an RF pickup problem in the first case which almost no one has anyway.  I suggest spending the money on the DAC, not on magic.

Take a look at the RME ADI-2 DAC FS. It excels at clarity & detail, yet isn’t overly bright or clinical. I have mine installed in my secondary system & I’m extremely happy with it. It has toslink input & is well priced at $1300. Best bag for the buck in DACS out there IMHO & I’ve never seen a negative review. There are many online stores that will let you return it without return shipping charges. It does a great job of doubling as a preamp, too if you don’t need a lot of inputs.

My main system has a PS Audio Directstream, which is stunning with a good preamp. They pop up used often for $2500, or so.

This topic is why I rarely visit here. The PS Audio is truly one of the worst DACs I’ve ever heard, and I just have to laugh whenever I see an r2r dac recommended - a technology dependent on multiple resistors being identical (not in this universe). That said, I have not heard many of those suggested here. I can say that the Weiss and Schiit were underwhelming, at best.

For natural sound, the Ayre Codex is still my favorite in this range.

Nothing comes remotely close to the current DCS, which I can’t afford. So I listen to lots of vinyl.

+1 enthusiastically on the Schiit Yggy. It compares well to anything I have heard, is painless to own and get serviced, and is far superior to any vinyl setup near its price range (far better than my Ariston RD11S/Grace 707/Benz Ace).

 I find it very natural with a tremendous sense of drive.
