Greetings to everyone on the thread.
It has been sometime since I posted on this thread but have been keeping up for the most part.
I received the ODSX Friday and per Steve Nugent will break in on my secondary system for another week 24/7. It has been since January of 2015 since I owned the ODSE. Since then, I have had the pleasure to audition and hear some new and some prototype dacs. That said, I am certainly glad I have this new unit. Unfortunately I will be unable to do direct a to b with the ODSE.
Although a more formal impression will be forthcoming, without question I would avoid the USB input and opt for the internal Ethernet direct to I2S converter, especially the M2Tech USB. Personally, I have never been a fan of the XMOS due to stability issues over many dac manufactures. M2Tech was more stable in this regard.
This Ethernet input is absolutely stable (unlike USB), produces a superior sound observed in dacs other than the ODSX, negates the need to use a server, negates the need of a driver, and I am able to stream direct Tidal, Linn, Qbuz up to 24/192 using Linn Kazoo and Bubble UPnP. This is very easy to set up and use. I will report back regarding ROON. This I am researching. From the ROON website, they are willing to take in sample units from manufacturers and task their RAAT proprietary software to specific hardware. Steve however is a one man show and if this cost anything to the cottage industry producer, ROON will not be an option. However, I will send my unit in to them if they are willing.
The Ethernet has galvanic isolation. I will test to see if Giso (galvanic isolator) or Waversa Smarthub (LiPo Powered, ethernet re-clocker/filter audiophile switch) have any sonic improvement and report back.
I know Matt and others have sent their units in for updates. Ditch USB and you will be glad.
Like the ODSE the ODSX runs hot. I sent my thermal measurements to Steve and he believes this is not an issue. The region over the Ethernet to I2S converter is the hottest but stable regardless of output gain setting. The rest of the unit will get proportionally hotter from low to high volume and low and high gain settings. If you have a high gain system like I do, then set it to low gain. Having it on high gain is not an issue per Steve, but it will run as hot or hotter than 300b tubes.
To everyone here, enjoy your holiday weekend and play safe.
