  1. Now it happened again: This leads to connection problems - not always but sometimes. I am afraid that's an unlucky combination. 2) and 3) (see above post) are fine. But 2) is not what I want to do on a regular basis. Looks like I have to step back and use the stock power supply... that's a pity.
  2. "unluckily" today I am not able to repeat the faulty behaviour, no matter what I am doing. But at least some more details about the power lights. With the Farad power supply: 1) When I switch the Furman on, the Farad gets power: Farad LED: goes from from flashing red/blue, red to blue. This takes at least 5 seconds. After the Farad LED is blue it takes at least another second until the ER Power LED becomes green. 2) What I also tried, when every device had power: I unplugged the Farad DC cable from the ER, waited a bit and plugged the DC cable in a
  3. My ER and my PC are both connected to a Furman power conditioner. The ER has three LAN cables attached: A-side: main switch (Cisco) and PC. B-Side: DAC. I use the Furman as the main power switch. This means: once or twice per 24h everything is completely powered off (also the ER). If I use the Uptone standard power supply (as included with the ER), then everything works reliable. This means all connections are available for my PC (LAN and Internet). If I use a Farad Super 3 (9V) power supply instead, then it becomes rather unreliable. This means in more than 50% of t
  4. @The Computer AudiophileThank you for asking and passing the info back to me. Really appreciated. Even if unlikely, it must be a quality issue with the Mogami cable, because: the Mutec AES/EBU output via Wireworld digital cables (3.5m) into my Genelec 8351B speakers works perfectly for any resolution up to 24/192 the AES/EBU input of my emmLabs DAC works also perfectly for any resolution, if I use a 10m long glass fiber cable (Weiss Chiron Glass1) between the Mutec and the DAC.
  5. And this maximum length of more than 1000 feet would be valid for 16/44 as well as for 24/192?
  6. Here's my observation: I connected a Mutec MC3+ smart clock device via its AES/EBU digital output with my DAC (emmLabs) using a Mogami Gold Series digital AES/EBU cable (110 Ohm). The length of the cable was 10m (ca. 33 feet). While this worked for 16/44 files, it did not work for higher resolution files (24/88) and higher. "not work" means either silence or a lot of noise and crackling. I guess that's due to the fact that the cable was just too long. But on the other hand in professional studio environments they also use rather long digita XLR cables. So I am a bit puzzl
  7. Excellent!!! I read the post. User Omid at avnirvana is right. I also checked the correct syntax here: http://convolver.sourceforge.net/configegs.html I edited my *.cfg file accordingly. It works now as expected, i.e. same behaviour/improvement in Roon as I have in J.River. @asdf1000Thank you very much. 🙂
  8. I am using the latest Audiolense XO version. I have passive speakers (2.0 Stereo). I am using a miniDSP UMIK2 microphone. Speaker measurement went well. For filter measurement I used the default (True Time Domain). I experimented with several target curves and ended up with one which I really like. I created appropriate filters: a set of *.cfg and *.wav files for J.River as well as the corresponding *.zip file for using in Roon. This means the convolution filter in J.River and the convolution filter in Roon are based on the same measurement, filter (TTD) and target, but... now comes my issue:
  9. Here comes my proposal: Genelec The Ones. Either 8341A or 8351B It has two big advantages: single point source (treble, midrange and bass). This means you can sit very closely to them (starting from ca 0.4m for the 8341 and from ca 0.5m for the 8351B) built-in digital room correction, i.e. you will use the Genelec GLM software. Even if the listening distance is short, the room correction has a huge influence. You can easily validate this by bypassing the room correction. What I would highly recommend in addition: use the digital input and not the analog.
  10. This is how I compare DACs or more precisely: (DAC A + Ethernet Roon Endpoint A) vs. (DAC B + Ethernet Roon Endpoint B) Equipment: Benchmark HPA4 Preamp/headphone amp with its remote control Sennheiser HD 800S headphones Preparation: create a Roon group, which contains Enpoint A and Endpoint B carefully adjust output levels of DAC A and DAC B (if necessary slight usage of the HPA4's input boost function) HPA4: activate the two used inputs, deactivate the unused inputs. Test Procedure: Start a test track Press "next input
  11. I went for the Sonore Signature Rendu SE optical and received it a few weeks ago. The combination DA2 V2 with the Sonore Signature is the best Streamer/DAC I ever heard. Previously I owned a used Vivaldi Stack (Upsampler v2, Clock, DAC v2). IMO, the DA2 + Sonore has more space/air around instruments and voices. Another highlight are the lows and lower mids... beautiful and unheard before.
  12. Hi @barrows thank you for your answer. Yes, as a long time reader/member of the forum, I know that you work for Sonore. No problem, I don't consider your post as advertising. I really appreciate your input.
  13. No, this does NOT defeat the potential benefit. You used the word "output" for the B side. It's better to consider the EtherREGEN as a moat, which separates what you have downstream (DAC or streamer (e.g. G2/NS1/ultraRendu/opticalRendu) + DAC) from what you have upstream (basically all other devices of your home LAN, including Roon server, NAS, other switches). As long as you only use one port from the A side, it does not matter which side you use to connect the DAC or the streamer which is attached to the DAC. The effect of the moat remains the same. If the streamer has an optical conne
  14. @Albrecht many thanks for your input, really appreciated! Though I have not yet ordered it, for the time being, I think I will go with the Sonore Signature Rendu. These are my reasons: I did own the first microRendu and still own the ultraRendu, my experience with both devices was excellent. The build quality of the G2 could apparently be improved a bit. There's a small German company which offers a modification with an improved power supply. This is in line with your remark about the build quality of the G2.

  15. I have a different opinion with regard to the DT 1990 Pro. I had it for several weeks, but the Dan Clark Audio Aeon was clearly better and much more comfortable. Admittedly the Aeon was also a bit more expensive. Therefore I don't believe that the DT 1990 Pro is a giant killer, as it was not even able to "kill" the Aeon. 😉 I guess, searching for a giant killer is just wishful thinking. I have/had the headphones below and the order of sound quality is not exactly spectacular: Stax SR009 (BHSE amp) > Sennheiser HD800S > Aeon 2 (slightly better than) > Aeon > Beyerdynamic 1990
