Warm, rich sounding interconnects?

Thanks for the additional background, Monsignor.

I didn’t realize that it had a low impedance - how would that affect the sound?

Compared to output impedances that are considerably higher (as is especially common among tube-based preamps and source components) it will to some degree lessen sensitivity to cable differences, and also to sonic effects that might otherwise result from interactions between that output impedance and amplifier input impedance. So to at least a small degree it works in the direction of improving the accuracy and neutrality with which signals are conveyed from the bluMe to the Wadia.

My assumption was that the Auris wouldn’t have the DAC in the path of the analog being an inexpensive device - but I have no idea.

Since Bluetooth conveys information in digital form it is the analog output of the bluMe rather than the optical output that would have the bluMe’s internal DAC (digital to analog converter) in the signal path. However, although optical interfaces are digital they have tradeoffs and potential downsides of their own, so the only meaningful way to compare the two approaches is to try them both, as you’ve done.

In any event, I would still suspect that trying to use a cable to compensate for the shortcomings of a $169 component providing DAC functionality as well as Bluetooth functionality, and having low output impedance, is not likely to be fruitful. And I would consider the relevance of cable recommendations which are provided based on experience with very different and presumably higher quality applications to be questionable at best.

Good luck, however you decide to proceed. Regards,

Monsignor, I would keep in mind that most or all of the multitude of cable suggestions that have been made are based on experiences with systems that are much more accurate and musically resolving than the results you’ve indicated your setup is providing. And the results you’ve described are not surprising, given that the most expensive Auris product I see listed sells for $169, while providing DAC as well as Bluetooth functionality.

So my feeling is that the intrinsic differences between the cables that have been suggested will be swamped by the inaccuracies of the Auris device, and will not be perceivable in your setup. Also, I see that the $169 bluMe device, which I suspect is what you are using, has a particularly low output impedance (57 ohms), which will also work in the direction of reducing sensitivity to cable differences. Especially in comparison with the tube-based products that I suspect are used by many of the others who have posted.

Also, I see that the bluMe provides an optical S/PDIF output as well as unbalanced analog outputs. If that device is what you are using, it may be worthwhile trying a digital connection to the Wadia, rather than the analog connections you seem to be referring to.

In any event, good luck as you proceed. Regards,
