Interesting point. I have no experience of the outboard clocks and cannot quantify the improvement vs cost, which is very substantial for big brother Esoteric and dCS. If anyone does have first hand experience, I would be glad to hear your views. I have tried to get the best out off the ud701n with Audioquest power cable and Ethernet cable, plus xlr and vibration mitigation. Whether any of these are beneficial is unknown, but do no harm other than to the wallet.
I guess there is no digital out as TEAC judges that the onboard DAC is already the strong point and why would anyone buy the product for its streamer section alone? In saying that, I have a Node130 solely for radio paradise MQA stream output via coax.
Hope you enjoy the demos, bosssound and look forward to hearing your views. I visited ATL many times as an aviator. Busy, busy busy!
