DAC diminishing returns

Regarding interconnects, I use studio quality, Mogami to my Naim and Van Damme coaxial to my Bifrost 2.  Audiophile cables aren’t warranted at my equipment level.  I should move way up the audio food chain before considering the expense of such cabling.  
Browsing around the internet I once read that Alan Parsons was quoted as saying, “audiophiles don’t listen to music on their equipment, they use your music to listen to their equipment.”  I feel this is true until you reach the a point where you just decide this is good enough.  Stop fretting.  Maybe my Bifrost 2 is enough.  Forget the pursuit and sit back and take in an artists work. In time, new equipment will be fun.  Thanks all.

Thank you for all this great advice.  Seems that the consensus is buy a better DAC.  In this price range, more money better sound.  For the record I stream with an Ethernet connection to a raspberry pie 3 with a digihat and a Toslink connection to my bifrost.  Volumio software.
I can afford much more, put sometimes I’m to frugal.

Thanks again for the “sound “ advice.  You have provided me with options that I haven’t considered.  Chord is one name that was not mentioned.  Their reviews are consistently favorable. Seems many use Chord as a reference.  Thoughts and experience with Chord would be appreciated.

Also, upgrading my RP 3 hat will happen if I jump to a better DAC.

electroslacker,  your Benchmark suggestion is well received.  I have read good reviews and some use it as a benchmark.  They have been out there for a long time and are still well regarded.

@larsman  

yes, chord was mentioned, my mistake.  Lots of good info in response to my question.  The more I research Chord, I’m not inclined to go that route.

In my area there are no dealers of high end equipment where I can go listen.

I like my Bifrost, but I would like more of a sound stage, which is what I’m trying to accomplish.

I have only listened to a variety of DACs below $1k. I couldn’t tell the difference.  That is why I asked the question, are there diminishing returns.  I want to buy a better DAC, but as you go up in cost is improvement worth it, or are they only marginally better, or not better at all.  After this very thoughtful discussion, I thank everyone.

I am coming down on the side of R-2-R.  

Sacrista,

I pulled the trigger and bought a Denafrips Ares ii.  I like it so far, it is a nice fit with my current setup.  Great return for the price. Better than my Bifrost, which I moved to a secondary system.  I did consider RME. It has many features that I probably won’t take advantage of.  I would probably be always fiddling with sound, driving myself nuts.  It sounds like a well regarded Dac.

Thanks
