I've been working on a FPGA transportable and desktop digital source as a "COVID project". Mainly clock-rolling. I plan to upgrade to weapons/satellite - grade clocks next year as audiophile clocks are just soso. Any London homesickness or you fully adjusted? Reverse culture shock?
Anyways, one final audio talk. I don't plan to stick around either. Maybe for a week. Maybe back next summer. As you know I H8 DAPs and OEM cables. I also H8 Android and iOS for audio. There just convenient. I'm just old school since I was one of the first 25 to purchase the very first CIEM on this site years ago so I'm pretty stubborn and picky on SQ. Thanks for your tolerance on my audio quirkeness and confidentiality over the years.
I subscribe to the Model View Controller when it comes to audio:
I believe things like screens which emit RFI should be kept far away from audio components, etc. There should be separation which is impossible with AIO units.
These days, I exclusively use a low latency realtime kernel Arch Linux OS with Summit-Fi audio software. It can probably run 8-10TB of storage without a sweat, but 1TB is the current bottleneck these days.
This has allowed me to get my transportable to a pro audio level on the Hugo2 since Chord DACs scale with source. Source is almost as important as the DAC. I also combine this with clocks. With clocks, I get soundstage expansion, precise imaging, PrAT, musicality, layering of bass and air out of the Hugo2. I get extremely tight transparent layered audiophile pro bass which is not possibile without a low latency realtime rig. So extremely happy how things worked out for this "COVID" project. It's like having a pro studio on the go. This direct streamer can probably compete with $7500 desktop commercial streamers.
As you can see below (photo) on the Jitter / Clock line of Premium DAPs, they all use clocks. To me, clocks are like a composer/conducter and the DAC is the orchestra. Without clocks, the orchestra is all over the place. So this setup is sort of like a hybrid DAP in a way.

I'm hoping to cut the size by 40% once new tech is released next year. Another very important detail is the power source. I'm using a good size juicy battery from the same battery manufacturer as Tesla. These are not normal batteries. These batteries allow Teslas quick accelaration and uphill climbing ability with dynamic power. So these batteries have low ESR (impedance) which allow quick fast dynamic power that is needed to extend for dynamic music. One of these small batteries is better than any LPS out there. I'm also running directly from the battery with solid core silver wiring. No battery holders or other bottlenecks.
I'm hoping to replicate and figure out a way to run a low latency realtime kernel with the upcoming Mojo2 or with USB DAC dongles as that is the trend, but that is a project for another time.
It's pocketable with loose shorts, but I'm hoping to slim down some more. About the size of a GoPro.
For the IR Remote, Up_Click = Next Track, Up_Hold = Main1 Playlist, Down_Click = Previous Track, Down_Hold = Main2 Playlist, A/V_Click = Play/Pause, A/V_Hold = Random playlist, Power = PWR. It's amazing to feel actual buttons instead of pressing a screen.
Hotspot is also setup for iPhone App remote control via iPeng.
