A DAC into a DAC?

Help me understand the signal path and clarify my options…

A little background: my digital source feeds into a pre-pro which I am using as a pre-amp only. It has Burr-Brown 24/192 DACs, (I don’t know which ones, nor can I bypass them). I am converting to a 2 channel system, which would include a new DAC, but I believe my pre-pro is limiting my options if I keep it in the chain.

Here’s my understanding: If I insert (between my source and the pre-pro), a new DAC that’s SUPERIOR to the pre-pro’s DAC, I assume that the pre-pro would limit or degrade the SQ of the new DAC. Correct? Is feeding the signal from the pre-pro an option in this case?

And if I insert some INFERIOR DAC into the chain, I assume that I couldn’t hear it at all, (preventing A/B comparisons). Another waste. Correct?

With my current set up, it seems like either I would have to abandon the idea of A/B comparisons of any new DACs OR that if I wanted to A/B, I would need to commit to a DAC that also functions as a pre-amp, or else buy a new pre-amp, which I don’t want)… Am I on the right track?

Thanks!

Keeping everything digital should just pass the digital signal through from your source to the dac. The data will only get decoded once.

If you are using 2 channel only and the pre/pro is staying on as the preamp, just run the source to the dac to a pair of analogue inputs in the prepro.

You could compare the 2 dacs and see what you like best.
