New dac

You have a very nice and well balanced system. The weak link on the PS DL 3 is the USB input. I assume you are using the DAC in the Node 2 for streaming purposes and the DL3 with your CD player as transport. I sold my first DL3 about 5 years ago, because I needed additional inputs (used a USB/SPDIF converter which took up the only coax input) converter. Just recently bought another DL3 to use in a second system. I believe the DL3 to be a very good sounding and well built DAC at current used prices. In my opinion it would take considerably more money to do much better (unless USB is required). If I was looking to upgrade beyond the DL3 I would consider a DAC that could serve both the bluesound and disc player. 

What is your budget for a DAC? 

Before you replace the DAC, see if it isn't the jitter from the Bluesound and transport that is causing this.  Do both sources lack mid-bass?

Here is some typical jitter:

You might try a Synchro-Mesh reclocker in the S/PDIF coax cable to reduce jitter to ~20psec.  30-day money-back, less shipping.

The Synchro-Mesh also has these sonic benefits:

1) Galvanically isolates the source from the DAC, eliminating ground-loops.

2) upsamples 44.1 to 96, so the digital filter used in the DAC is a better one, not brick-wall.

Also, I recommend to get a better S/PDIF coax cable, one that is high-performance like the Reference BNC with RCA adapters or the Standard BNC with RCA adapters.  The Standard BNC is only $275.

Do you find lack of bass on both CD and Bluesound Streaming?
Are you using the Bluesound DAC or outputting to the PS Audio DAC?

Did you have this issue earlier-before DAC and CD player?

I'm actually using the PS audio dac instead of the node 2 dac, which sounds better to me. Music seems more alive with a wider soundstage then the node 2s  dac. 
   I do remember hooking up my marantz pm 8004 last fall and felt it had more punch, but vocals weren't quite as clear as with the Belles amp. 
   I guess what I want to know is if the  dl 3 is still a capable dac giving its age.

I had a DL3, sold it for a highly reviewed DAC-pre, and was quite disappointed. I tried a highly regarded one box CD player; disappointed again. Then I bought a newer PS Audio DAC and it still didn’t feel right. So I bought another DL3, thinking I’d wait while DSD matures and falls in price. But the magic is back! I think the DL3 is one of those special components where everything came together perfectly. Vandersteen 2Cs, Linn Sondeks, etc. I love mine. I think it’s going to be here a long time.
