Why do you think that the Pro-Ject DAC is limiting the sound quality of your system? If anything I would get rid of the Pass amp and get an amp with a lot more power, say 200wpc. The Pass's 25wpc is really limiting the dynamic capabilities of the Sonus Faber speakers!
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.
