  1. One thing worth mentioning is the T+A literally scales with source quality input via DSD path, possibly due to the simpler yet very HQ discrete DSD implementation (lack of processing, pure). I (had) an SMSL D1, a well measuring at least dual 9038 pro DAC. I also had the "chosen" NUC i7. Fitted Apacer industrial ram to it. The T+A took a big leap forward, bodies becoming very dimensional and fleshed out. The other sounded like hifi still, pin-point placement but no flesh to it like the T+A. Was startling to witness. At that point I gave up on measurements....
  2. There are few industries in the world where people pay so exponentially for "quality" this much 🤣
  3. I had to disable background timer tasks on my OpticalRendu + OpticalModule combo, then I got zero interrupts at DSD 512 rates. Otherwise its excellent (for a standalone streamer). Not cheap though. If you can stomach running a PC near your T+A, the JCAT XE gets my vote, with a suitably HQ 5v PSU. I use the MPAudio LSIB just mentioned here. It left all my streamers for dead. Shortest path won out in the end (!).
  4. The "phase noise" you hear is the Amanero FW losing timing; In short there's been an interruption to the datastream leading to this. On streamers able to keep a stable signal this isn't an issue with be10/11 whatsoever though. It can be something as simple as background timer tasks interrupting the stream as I found on one streamer (!). I had the same problem with the Ultra Neo before be10, I never found it very stable at DSD 512 rates tbh. Sold mine on as a result. edit: on XMOS based DACs you'll hear a quiet pop when this happens (streamer unable to keep buffers full).
  5. I've found the same thing for years, spend in vibration control going much further than cabling.
  6. I should add- when the Ryzen 3900x ran with stock settings (XFR, default vcore etc) it would consume 125w (wall) steady using my selected filters + modulators with HQP. When dropping vcore max to 1.0v, wall consumption dropped to 80w (wall) steady, and yet it was able to achieve the same processing, albeit with absolutely slaughtered sound. CPU clock speed was closer to 3.3ghz iirc instead of 4ghz when vcore not modified. Is it possible that when power shedding / saving mechanisms contribute heavily towards degraded SQ? If so what metrics would we investigate to help correlate this? C-State transitions? Current demands?
  7. Cheaper than swapping components / boxes 😉 for my amps the change was not subtle, for example. Can try standard sizes at home on trial.
  8. Taiko Audio once produced a copper plate + panzerholtz upgrade for the T+A DAC 8 DSD. It involved Panzerholz bed for the PCB itself, along with Panzerholz feet inserts. To summarise, I also have the double Daiza platforms under the same DAC. Removing the double Daiza platform showed in my case little delta from simply using the copper + panzerholz feet supplied in the above kit. I still keep the double Daiza's for the added height, though! edit: the impact of the copper + Panzerholz was rather dramatic. One of those "that cant be possible?!?" moments.
  9. I tried the EC modulator with a 2s filter lately, and found it played for about 5s at a time before a blip. Do bare in mind though that I have my cooling settings in my BIOS set to "silent" which means the CPU is easily getting to 70c when operating in EC mode. I may try again with "normal" cooling mode on. But yeah, T+A clearly works best at 512 so .... no big deal.
  10. I can give it a try. I'm using poly-sinc-xtr at DSD 512 rates, which according the turbostat (or whatever util i use) means all 12 cores are actually running a workload of 1.9ghz~ quite evenly. Yes, if i was running EC i'd be in trouble as noted the Ryzen cores like to use PBO to achieve high single core speeds.
  11. I tried this with a Ryzen 3900x + JCAT XE, running HQPlayer Embedded. The good news is, yes MASSIVE gains in cooling to be had, and I was still able to run my filter + combo of choice. Wall draw also reduced by 25w (100w vs 125w). This was achieved by simply setting the CPU to a lower vcore limit (undervolting), which caused the CPU to "budget" power accordingly. This automatically limited the max clock speeds of cores, but they werent entirely far from top end frequency range either The bad news is - it absolutely slaughtered dynamics, impact, low-level detail.... quite frankly it was like running an ARM streamer again. Has anyone else achieved a "undervolt" on the Ryzen 3000 series without it killing the sound signature?
  12. Pretty much - I'm running an SMPS in my HQP server which was on another power circuit in the building. I do agree with Nenon's findings (less depth, mode width - marginally) to a degree but there are certainly benefits of not having a ton of noisy SMPS and PCs near your hifi equipment.
  13. Yes, PSU has plenty of headroom (5A), although not drawing power from USB port. FWIW, the SlimRun USB works randomly - either for hours at a time, or suddenly stops with the XE. Happens during track changes. It does seem once in a while the USB hubs do get confused for others too. They are native USB 3.0 hubs, but accepting USB 2.0 devices. Interestingly, I could never get it to throw up issues with a USB 3.0 device attached via the XE. A few other reviews of the product itself suggest this is happening with other USB ports too, so not strictly an XE issue. It appears from the kernel logs that the USB hubs are resetting when faulting (i.e. disconnecting). Also worth mentioning, when connected in Linux, the kernel would report the hub connecting at 5gbps, and its downstream devices (e.g. the DAC) ALSO rated at 5gbps, when ofcourse the DAC is a USB 2.0 480mbps device. Did try injecting a USB 2.0 extension between SlimRun and PC, but it wouldnt function without USB 3.0 pins. Will eventually try a few more optical extenders. SlimRun USB optical otherwise goes recommended.
  14. I tried both ways (USB port power on, and off). On other USB ports, powering it internally/externally didnt effect its stability.
  15. Just a word of warning - I have the JCAT XE card and found both of my Slimrun optical USBs would stop communicating with the DAC. This problem did not occur with the Ryzen onboard USB ports, though. Real shame as it was very effective otherwise.
