  1. Well, my Audiophilleo2 + PurePower combo found a new owner the other day, and I've now ordered a Marian Seraph D4 PCIe soundcard for AES/EBU digital output duties fed into my BCA DAC/preamp. According to plan it should arrive next week, so if implementation runs smoothly I'll have some first impressions ready in about a weeks time.
  2. There's no replacement for displacement, as they say. Added the bigger Electro-Voice HP9040 Constant Directivity horns to replace the previous and smaller HP940 dittos, so the pro cinema EV speaker system is now named TS9040D LX (actively driven). Crossed at 500Hz.
  3. I'm in the decision making process of purchasing a Marian Seraph D4 PCIe card for AES/EBU digital output duties into the XLR input of my DAC/preamp. A dedicated, braided digital cable with 0.5mm Mundorf Silver/gold wires will be used here, that has previously served me with a RME HDSP 9632 PCI card - that no longer fits in the recently upgraded PCIe-only mobo, btw. If all fares well it could replace my Audiophilleo2 USB to S/PDIF converter + PurePower that's currently sitting in my system. We'll see how it goes, but the timeline mayn't be until a month or two. It's funny how the M
  4. I would think it's enough wattage as well, but indeed; practically, as it applies to sound quality, it may be a different matter than the requirements for mere functionality. Interesting findings, thanks. That's quite the PSU-headroom afforded here for your core i7 set-up, and makes my sole RM550x seem anemic for a seriously malnourished audio PC by comparison. I'd be tempted to say, in your case, more than or certainly in addition to "better" the sheer grunt of power is a primary factor (unless of course more power simply equates into better). Some might feel better is
  5. Sure, using the Corsair RM550x. It would seem sufficient? Not using a separate video card.
  6. It seems the overall gist here is that, sound quality-wise, the more powerful the CPU the better. I'm thinking of upgrading my existing Intel Core i3 9100 to an i7 9700. Would that make any appreciable difference with regard to sound character/quality?
  7. Thanks for chiming in. Simplicity I try to maintain as well, though from my chair/to my ears and mentality towards all of this I prefer working around a modular approach DIY music server/HTPC, as opposed to an all-in-one streamer package. I don't know what it comes down to technically in detail, but generally I find a full size music server with a higher wattage PSU and more powerful CPU (as opposed to a NUC-like, low wattage/low computing power solution) to sound more fleshed out, with better fundamentals, more balanced and effortless. What I've loathed even with many USB-implementation
  8. Maybe I could pinpoint my aim a bit with above inquiry. It would seem what I'm after is an old discussion already old 10 years ago, basically essentialized into: USB vs. S/PDIF - which is or was better? Since asynchronous USB emerged around '10 or thereabouts that discussion, which may at first have been about noise vs. jitter (as represented by USB and S/PDIF, respectively), largely had the asynchronous USB implementation come out victorious (not least externally powered and clocked) - theoretically, at least, and from what I'm able to assess. But where do we stand today, further
  9. The USB output from a music PC to a receiving DAC USB input - typically via a dedicated, audiophile USB card with (expensive) external clock and PSU - is a popular option among computer audiophiles, perhaps even the preferred route in the über-offerings of cost-no-object music servers out there. Does it come down to PCM-based sound quality mostly, and/or is DSD playback and unrestricted sample rate capabilities a strong incentive for using USB out-/inputs as well? What about S/PDIF connectivity or I²S, or USB to S/PDIF converters - why do people use the particular out- and input modes they do?
  10. Cool unit, thanks for pointing that out. Quite comparable to the Lynx, it appears - maybe even more so. I'd intend using it with AES/EBU output via my dedicated Mundorf-wired digital XLR cable. The RME9632 AES/EBU output compared quite well with my Audiophilleo2, so the HDSPe AIO Pro should be very interesting..
  11. It's a shame the EVGA doesn't sport other S/PDIF outputs like coax or balanced AES/EBU, other than Toslink. My RME9632 does, but it doesn't fit into the PCI slot of my new Gigabyte Z390D mobo. The Lynx AES16e fits the bill, but it's not cheap..
  12. To my ears, in regards to the sound of Toslink, I've found the SQ to be dependable in particular on the specific optical input implementation of a given DAC, but what you point out re: the side of the PC-"provider" certainly makes sense as well. Toslink can sound very good, again IMO, and is often leveled a generalized 'sub-standard format' sentiment - a bit unfairly, it seems, but I would have to make a more thorough investigation and comparison to be able to make a qualified assessment. The PurePower unit arrived today and is up and running again. We'll see whether it
  13. @davide256 Thanks for your reply. It turns out my PurePower unit has returned from the dead, so to speak, after being disassembled and looked further into, so that's good news. The less good news is whether it's a periodic malfunction possibly linked to a loose connection, maybe even from one of the SMD components. Another friend of mine working at a robot development facility might take it for a look under a microscope to get some clarification on the matter. In the meantime I'm considering alternative options. The optical input on my BCA DAC/preamp is high quality (t
  14. Hi, folks The PurePower unit feeding my Audiophilleo2 USB to S/PDIF converter died on me the other day (i.e.: likely not because of the battery, which was replaced only a few months ago), so while a technically proficient dealer/friend is looking at it I'm considering my options in case the PP unit has departed these realms for good. As is I'm simply playing USB to USB from the MB of my HTPC to my DAC/preamp, and while sonically serviceable the sound lacks expansiveness/dimensionality, resolution, transparency and overall engagement without the AP2 + PP in the chain.
  15. Felt, perceived - I guess that's the subjective nature of an experience and what we can really go by in our listening, correlated though not only to itself but a set of references - be that a live one, measurements and theory. Where I've written about displacement, implementation and SPL's it has been largely unspecified as to the particular methods, and for a reason: it was to first and foremost highlight the need for physics to be accommodated in the face of a stance that would try to more or less "dodge" them. As I've mentioned previously I'm fully aware realism to be attained needs a numbe
