Any improvement of using 2K$ Dac with Cambridge CXN

@wallpoom IMO it depends on what your goal is. It kind of looks like you're looking at all-in-one network streaming DACs, but asking if that is a better option versus a standalone DAC where you continue using the Cambridge Audio as your network streamer.

I would say technically you're more likely to get a higher quality DAC and overall better sound at a given price point if you continue using your Cambridge Audio as the network streamer and purchase a DAC, ignoring MQA.

This article about jitter may help, but in short imagine a clock or metronome sometimes being a little off whenever it ticks. Either the next tick comes a little too soon or a little too late. If you're trying to keep time based on the ticks, and they're not always exactly right, then whatever you're doing might be a little incorrect.

@wallpoom separating out the DAC and the streaming technology in order to upgrade those over time without constraint does favor going with separates.

The only issue would be MQA, if that is important to you, since that technology usually requires both the network streamer and the DAC to support MQA.

I would recommend getting a Lumin U1 or U1 Mini for the network streaming and a separate DAC that provides the sound quality you're looking for. Lumin's software is constantly updated, and their hardware is excellent and compatible with non-Lumin software too. Since you're in Thailand, I think you should be able to demo one locally.

Your choice of DAC will come down to personal preference.
