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 I am wondering, though, whether the Music Player II might be outdated.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!

Chord Mojo looks awesome but looks like it doesn't support MQA.

Would the Pro-Ject Pre-Box S2 take input from a CD player? Looks like it has optical and USB in, plus a single coaxial input.
If CD player has optical or coax SPDIF output then you would be good to go using the Pre-box as DAC and preamp.
The DAC is the most important part as it will convert the lossy digital data to analog. Jump to chord dac and you will see

Up to a point I agree with reubent but... big but. With digital stuff it is different. Digital is a whole different ball game. Since the human ear is extraordinarily sensitive to anything that sounds un-musical, it can react to seemingly very minor shortcomings which sort of bug you until you either just throw your whole digital rig in the trash and go back to analog, or upgrade.
