Is my DAC my weakest link?


Hi everyone,

I'm new to this sort of thing. I recently bought the following system used:

Thiel CS2
Rotel RC-1070
Audionics BK-ST 140 (BT-2)
NAD 5000
Music Player II DAC

It sounds great and I am very happy with it. I am wondering, though, whether the Music Player II might be outdated. I know everything is old (hopefully some of it in a classic sense), but I have been wondering whether more recent technology might have greatly improved DACs. Would it be worth it to invest in a more recent DAC, and if so, what price point would be roughly commensurate with the system? (i.e. no need to improve the DAC beyond the capability of everything else).

I stream Tidal HiFi through Audirvarna Plus to the DAC.

Thank you for your insights!

The issue with DACs is that modern one's (< 10 years old) do much better with Redbook (44 kHz / 16 bit) playback than old DACs.

If you can hear a big jump in sound quality when you go to high resolution, that goes away with most DACs today.

I like Mytek, Schiit is also an inexpensive option which works really well. Topping is an absolute bargain if they fit your budget better.
I recommend the Chord Mojo. There is one currently listed for less than $400 on Agon. It's not mine. I use the Mojo as a headphone DAC when traveling. I know that others on this site use the Mojo as the primary DAC in their home systems.   
Based on that component list I would have to say your weakest link is the lack of power cords, interconnects, and speaker cable. Power line conditioner? My guess is you are still using the factory fuses. Cables laying right on the floor. As Kurtz says in Apocalypse Now, "The horror. The horror."
