I sometimes feel that when it is possible to describe something unambiguously with words, that something cannot be very interesting. But I woud say that the sound opened up in all directions, mainly height and depth, that it became holographic and enveloped us. Also bass became more pronounced and musical at once: like a low melodic line that sang, rather than just being 'bass'. Thanks bodiebill, well said! I thought, or actually still think, that I already have quite a big soundstage. But the SR4 added something I would never thought being possible from two very small speakers in front of me. And the base is what I liked the most, because in my room and the way my setup is positioned in my L-shaped room, bass is a big challenge, and I accepted the fact that it would always be like that as long as I live in my current home. The SR4 made an end to that problem, instantly.. Oh, and for @seeteeyou, regarding warm-up time and so on.. We listened to the SR4 only 15-30 minutes tops. It was cold when we started listening, and it wasn't been used by bodiebill for quite some time, so I am already dreaming about what would happen when it's properly warmed up :) I have around 4 weeks to go before I get my own, I have to be patient...

Qhwoeprktiyns Posted October 16, 2020 Share Posted October 16, 2020 @bodiebill and @Huubster I suggest next time, if you get a chance, you try the UPL with an external power supply. I think it improves things over a direct connection from a PC/laptop. I use a large 5v battery pack from Goal Zero (https://www.amazon.com/Goal-Zero-SHERPA-100-PD/dp/B07VFY3DWX?ref_=ast_sto_dp). A quality linear PS should provide sonic benefits as well. Link to comment

A quality linear PS should provide sonic benefits as well. Happy to try. Actually (as I believe I reported somewhere earlier in this thread) with the U192 I compared a Ghent Y cable with external clean linear power (6VDC linear converted by LR3045 to 5VDC) to a Lush USB cable without separate PS. Surprisingly, the latter easily won. However, I assume the USB cable topology is less important for the UPL (as in that case it does not carry audio data but just occasional control signals) so I should definitely try the same again but with the UPL. A bit short on time these days, but I will report back once done... audio system Link to comment

If you have the possibility to raise the input voltage to 7VDC or similar, the LR3045 will improve in performance so could perhaps make an audible improvement. Link to comment

Thanks for the suggestion. Indeed ripple will be lower when the delta is larger. And I believe that the LPS's output voltage can be adjusted with an internal screw, I estimate somewhere between 5.5 and 7VDC. So I wil try that. realDHT 1 audio system Link to comment

Fanclub you say, are you as enthusiastic as all of us here? 😊 More than you think..... so far the Mosaic was always my GOTO unit and i never heard a DAC (here in Israel) that sounded as good as it - well i didnt heard them ALL but quite a lot. And the new UPL - for me is the BEST source EVER for pure anologue/digital sound. I have the intona USB isolater always infront the Mosaicm just to mention. As far as power problems - not all locations are affected by this, I mean that in my house it works good, at my friend (where the speakers are set) the Power line is perfect since he rewirded the whole line to the HiFi system. Yes i will do more test to find out how this affect - but it looks like that almost every DAC with internal standard PS is affected. Huubster and szczemirek 2 Link to comment

Well - since the QA390 is battery operated and looks like the filter in done it in the right way - it sound VERY good and close to the UPL/USB - ONLY and ONLY when play WAV files in the wav SF (!!) , once you connect to USB - you will need Intona to Isolate and a good USB cable. Still - the UPL is beter sounding - i just cant even pinpoint or find something bad to say. But QA is close! 5 days a go we had a 3 hours sesion at my friend (speakers) and we were like extatic and glowing from the great sound . Huubster 1 Link to comment
Qhwoeprktiyns Posted October 16, 2020 Share Posted October 16, 2020 I have the Mosaic UV as well and I really liked that DAC a lot as well, but I never had a very good USB source to use it with. In spite of this it sounded quite good. In some ways, the Mosaic UV may have been better than the MOS16 (which came just before their current DAC) but with the MOS16 also came the UPL...

With the MOSAIC it is important to have bit perfect as also with the new U192- without it, it just sounds like everything else. So no software voume and no convertion and in Tidal i chose "let Tidal take over... sound" so the volume is also fixed - the only volume is on the PC that controls the Mosaic internal volume swhitching. So the U192 connected to external amp and i control the volume on the amp. Link to comment
Qhwoeprktiyns Posted October 17, 2020 Share Posted October 17, 2020 This afternoon I took the UPL+Fractal for another comparison against a Terminator DAC + SOTM streamer (with reclocking and EtherRegen). Everyone present (4 other seasoned audiophiles) agreed the UPL+Fractal was superb! I was eager to have a chance to do this comparison again, as I had been a little underwhelmed the first time (I mentioned this here a couple months ago). What has changed since? - revised UPL board including the 20Mhz bandwidth limiter, same as the U192. Bodiebill and Norton have that model, and anyone who has purchased the UPL since a month or so. - use of a proper 5v battery supply instead of a direct connection to PC, though we did not compare without the battery supply. Comparison of the various configurations, including using the UPL with the Terminator, showed the magic lies in the combination of the UPL+Fractal (my personal conclusion). I am eager now to see what ECD will accomplish next, in 2021 if I understand correctly, with the PowerDAC that they have mentionned on DiyAudio :) Link to comment
bodiebill Posted October 17, 2020 Share Posted October 17, 2020 With SOtM streamer + Terminator, where you streaming over the network? Or was the SOtM stand-alone with an attached USB drive? Whatever the case, your findings are similar to mine. However, do not underestimate the Terminator. When paired with the SDTrans384 SD transport -- a stand-alone source in principle comparable to the UPL -- it still performs at least as good as (or better than?) the UPL + Fractal DAC combination. audio system Link to comment

Why do you think u need this for the UPL? Does it matter if i connect it to my laptop and it works on battery? What cable do i need to test it also so it will be connected to PC for control and external power? Link to comment

SOTM was running Roon with local files (so not an attached USB drive). I would say the main conclusion, agreed upon, is that the UPL+Fractal sound exceptionally good, and certainly better than the Terminator with SOTM, which is already no small accomplishment given the large price differential between the two (all included, you can multiply by 6?). To be a little more diplomatic: the comparison with the Terminator + UPL would have to be done over a more extended period of time, though to my ears it was fairly clear, and it might be a matter of preference. As for the Terminator with other sources, it is clear that may change things significantly, but we did not have the opportunity to check that :) Link to comment

What cable do i need to test it also so it will be connected to PC for control and external power? To be honest - I would not guarantee that it makes much of a difference. I have done some comparisons at home (with external battery power vs. power from the NUC which has a cheap SMPS), and prefer the battery power but I have not compared with a laptop on battery power. I was using this cable, which is quite cheap, if you want to try it yourself: https://www.audiophonics.fr/fr/adaptateurs-divers/cable-adaptateur-usb-b-pour-alimentation-jack-55-21mm-femelle-p-8332.html Link to comment
Qhwoeprktiyns Posted October 17, 2020 Share Posted October 17, 2020 As I mentioned before, I was curious to do this test as I was really disappointed with the results the last time. You can argue about the significance of sound differences, but this time I think it was clear that the quality was really very good and obviously so. We only tested the UPL, I did not bring the U192 (USB interface). But what this confirms, in my opinion is: - both the UPL and the Fractal DAC contribute to provide excellent results (the Fractal DAC is not a lesser DAC, the star of the show is not only the UPL) - there is nothing really missing in the sound quality - there is no "tradeoff" between better transparency and precision, and other aspects of sound reproduction - ECD knows what they are doing, and we can trust they can only improve on this !

Most likely it depends on how good (or how bad as shown below) your laptop really is, so far DA96ETF didn't seem to be too sensitive to its source of power but unfortunately UPL96ETL really suffered the poor power quality from a laptop https://audiophilestyle.com/forums/topic/24966-ecdesigns/page/47/?tab=comments#comment-1084012 On 10/10/2020 at 4:49 PM, Huubster said: I experienced that the real benefits for me are elsewhere, and that is on the source end of my chain.

Back in the days when we could only go up to 99 albums, it's hard to tell what will happen to the longevity of the USB port if USB drives were removed / inserted repeatedly. Adding USB extension cables or USB hubs wouldn't be such a good idea either, thankfully we don't have to worry about any of that now when we could simply unplug one end of the USB cable while leaving another end alone. It's also fantastic to know the fact that both UPL96ETL and U192ETL would perform so much better as long as we're able to feed them with one of those top-tier power supplies. Link to comment
Huubster Posted October 18, 2020 Share Posted October 18, 2020 Reading your latest post @seeteeyouI realized I can test the UPL with power from the Innuos, since I have a very capable USB Y-cable in use between streamer and U192. Plugging the signal side in my laptop and swapping the B-side from U192 to UPL should do the trick right? :) Don't know when yet, but I will give it a try one day. Link to comment
