afrancois Posted January 17, 2020 Share Posted January 17, 2020 This is only the third song that is playing with the ER in the chain and already feel compelled to express my joy. To be honest I had been wondering if the ER would bring anything to my system, because I consider it already highly isolated. Luckily there was nothing to be worried about. While I'm burning in the ER and while it's connected still in front of my AQVOX, I already hear a very obvious improvement. I will replace the AQVOX with the ER in a few days after I have done some other tests with transducers. The anticipation had been high and this is a VERY nice birthday present. The unit was sent by Uptone on my birthday 🙂 Further listening impressions will follow. Back to the listening couch now... Superdad 1 Link to comment
Popular Post afrancois Posted January 31, 2020 Popular Post Share Posted January 31, 2020 I wrote my initial impressions of the ER whilst it wasn't yet where it belonged in the chain. I just had it placed between my EdgeSwitch 10XP and the AQVox that's connected with the sMS-200 Ultra. The 10XP is connected using fiber to the "core" switch. During my second test, I took out the AQVox and I used fiber to connect to the ER directly to my main EdgeSwitch 16 XG fiber "core" switch. As much as I wanted this to be the best solution, it wasn't for me. Although everything was very clear, it sounded a bit harsh. Because I don't want to go down the route of using fiber attenuators, I'm now using an Ethernet cable that goes into the A side of the ER instead. This cable comes from the 10XP which is powered by two LPS 1's. The ER is powered by an LPS 1 (not the LPS1.2), has a ground connection and gets its clock input from my REF10. This setup simply blows me away. The ER finally shows the true potential of my amplifiers for my entire music collection. And while I haven't done test yet, it is quite possible that my local streaming solution now surpasses my CD player. This is high praise! For some reason I always preferred to power the switch with an LPS 1 and not the LPS 1.2. This was already the case with the AQVox. RickyV and One and a half 1 1 Link to comment

The differences are minute with the LPS 1.2 compared to the stock SMPS. But minute is enough for me to opt for the LPS 1.2. Yes the ER is earthed. I made a special cable for it. so-no-mah 1 Link to comment

I see you have 2 EtherRegen’s. Did you hear an improvement by adding a second one? I have an AQVox in front of the eR. Link to comment
afrancois Posted April 9, 2021 Share Posted April 9, 2021 3 minutes ago, PYP said: Yes, in my system, there was a significant improvement with the second eR. My network is rather simple: ISP-provided router/wifi/modem box > in-wall 5e ethernet > ... therefore I haven't worked on improving the upstream at all. All my improvement have been after the in-wall exits near my system. Mine is a bit more complex. I have fiber optic core switch in between and a bunch of other stuff to maximize electrical shielding. An other important part of my network setup is that all WiFi antennas and computing power (servers) are far away from the audio equipment. All switches, routers, modem are on LPS’s.

I've never had a sibilance issue (except when gear or cables were breaking in), rather the issue I had was HF just not sounding completely natural. It was subtle, but my ear is sensitive to that. I have no familiarity with the Lumin line, so don't know the sound signature or if other users have found sibilance issues. I tend to look at the DAC/Streamer as the origin of those kind of issues. Assuming that it isn't the recording itself. As we all know, cables can tip the balance of any system. Perhaps you have already experimented with different kinds. I've found, contrary to what many suggest, that powering all equipment from the same power conditioner works well. A dedicated outlet to the power conditioner is optimal. Previously, I used two dedicated outlets, one for amps and one for everything else. Surprisingly, to me at any rate, that didn't work as well as one outlet. Hope you can track down the problem. One of the ways for me to eliminate digital harshness was to replace all SMPS with LPS. I mean all, even for the coax amplifier from the tv/internet provider. Even all switches are on LPS. QNAP server running Roon server is far away and connected using fiber to eliminate any electrical noise coming from computers. I’ve gone to some really extreme measures to get the maximum out of my system. You have a very nice system but as I found out there is still room for improvement. Link to comment
