@melm , @bill_k correct, I think most everything there. The one issue with custom build like this is the bespoke nature of the total build including power supply. Vast majority of this not applicable to most if not all members here. To try to put this build in some perspective, last comparison prior to original builder selling, preferred this to Aurender W20SE, a subjective opinion, but there it is. This comparison at time when build was in earlier configuration, lesser processor and power supply much less quality than my JCAT Optimo. Original builder/owner only sold after comparing to Taiko Extreme, $35k, which he ended up purchasing.
So, based on this and a handful of other builders with similar or exact same build and their estimations of sound quality, this custom build right up there with best. If anyone interested, the long and winding road covering this build and others can be found at Audiophilestyle forum, one thread is 765 pages or so at last count, so pretty dense reading.
At this point, I have yet to try vast majority of possible combos of music players and end points, choices include all Roon, Roon with embedded HQPlayer, Roon with embedded Stylus EP (Euphony's proprietary music player), all HQPlayer with Roon endpoint, all Stylus, Stylus with Roon endpoint. Entire custom build runs on Euphony operating system, this is proprietary OS based off Linux running on Windows ATX motherboard, generally running at less than 1% of available processing power which means this operating system has only the most essential processes running, means low noise, higher resolution.
At this point I can only say the resolution of this setup is incredible! I've been experiencing sensation of live performers in room for a few years now, but the added detail of this streamer has heightened this sensation. The noise floor has dropped down to the extent I now hear the lowest level details, voices are just amazingly lifelike, the smallest inflections and breath now heard. And all performers and instruments are increasingly in their own place on soundstage, individualized to the extent of much more replicating what one hears at live performance. And then also much more relaxed, sense of ease, more analog like presentation, which tells me jitter level much lower. One of the major design principles of this streamer build was paying great attention to latency which results in much lower jitter. As mentioned above I have yet to try most combos of music players, saving optimal music player combo for last! Also, still not close to optimizing usb as I'm using motherboard usb vs. JCAT USB board I plan on purchasing.
As for how all this applicable to 005, none of this wonderful performance would be possible without it! I still hear no sins of commission or omission. 005 not suffering a single bit with being more exposed, sometimes components suffer with greater exposure, defects previously unheard become heard, 005 has only increasingly excelled.
The fact is I'm so entirely happy with my digital setup, I'm finished, not worrying about $3k dac not being expensive enough. I've now turned my attention to the vinyl setup, already have some items on order, going to be major undertaking to get this up to digital.
