How much should I spend on a new DAC


Hello Gents. What would be reasonable sum to spend on a new DAC relative to my current audio rig.

Speakers: Sonus Faber Olympica II

Integrated Amp: Pass Labs INT-25

DAC: Pro-Ject Dac Box S2+

Speaker Cables: Kimber 8VS Bi-Wire

Power cable: Kimber PK10 Base

Interconnects: Audioquest Tower

I must say I'm very happy with the music coming out of my speakers but It's obvious that the DAC is not the same league as the rest of the equipment.

I have a pretty similar setup with Olympica Nova II powered by Pass XP12 and XA30.8 and it sounds really great. I understand the XA25 should also be excellent with our Olympicas. As for the digital front-end, your system will respond to and be very revealing with every improvement you make there. After having had a Schiit Yggdrasil,I was able to get a 2nd hand dCS Bartok. Definitely no regrets and if I could stretch to a Rosinni I'd get it tomorrow. You could consider a Holo May KTE as it also works really well with Pass and Sonus faber. Denafrips don't do it for me.

Your biggest bottleneck is probably using the computer as your source, and adding a good streamer will make a huge improvement and probably more than upgrading your DAC.  That said, for around $3k you could add both this Innuos streamer and Gustard DAC and you’ll be in a whole new world of performance.  Also, ditch Tidal and give Qobuz a try.

Just my $0.02 FWIW, and best of luck.

I understand the computer can be a weak link. But, even though if I add a good streamer I will still have to use the PC as a roon core. I don't think using a  LAN connection instead of USB will make such a big difference  

I agree that separate streamer and dac would do you a lot of good. However I would put the brakes on the r2r recommendations for a dac. I had an Ares II and then bought a delta sigma Gustard X26 PRO and ended up selling the Ares II. No doubts that the Gustard offered a much better sound in my specific system. A Bluesound Node 130 connected to the Gustard would be a great start for about $2k. Then the upgrades start... Made quite a few myself but stuck with the Node and Gustard. Enjoy the trip.

I agree that the PC is a limiting factor and would get a streamer/DAC combo. HiFi Rose, NAD or Cocktail Audio come to mind,
