  1. It worked! I left the BG7BTL on with the supplied SMPS overnight then removed the SMPS and connected the LPS 1.2 and the BG7BTL turned on. Left it on for a week so to be certain no stabilization issues were affecting the sound. Then I tried: a) LPS 1.2 feeding BG7BTL thru Ghent DC-GAC4 and ET07 BNC 75 ohm into eR, and eR fed by Uptone SMPS, vs. b) LPS-1.2 feeding eR thru DC-GAC4. I'm preferring b). More details, definition, across the frequency range. With the BG7BTL it is mellower which isn't bad with some recordings, but I think I loose definition. And clean
  2. @Superdad Thank you! I will leave the clock on overnight and try tomorrow with LPS...hoping a warm clock doesn't demand as much current...unlikely to work, but it's cheap to try. @Mihaylov It's a Symmetricom. It's interesting others with BG7BTL with Symmetricom ocxo and LPS-1.2 didn't have this issue.
  3. Hello. Today I tried to use my LPS-1.2 to power the BG7BTL and had an error. I believe others have used this combination without problem so I'm wondering what might be wrong? The LPS-1.2 is set to 12V, powered by the supplied Uptone SMPS, connected to the BG7BTL thru a Ghent DC cable. Upon turning on the LPS the led goes from red to orange and when it wants to turn green the power and alarm leds on the BG7BTL blink briefly and go off and the led on LPS blinks red, and this cycle continues for as long as keep the LPS on. The BG7BTL output wasn't connected, if that makes
  4. @markf31 Steep learning curve. Be patient. I suggest spending time at REW forum (I think it's at AVSforum), read, learn. First off, your vertical axis includes 0-180dB which hides what is really going on. As @sledwards mentioned, 45-90dB is better and will let you see more (90 or whatever is your highest measurement). Read about windowing. I guess you want to measure how the room-speaker interact rather than design a speaker. The best way to look at lower octaves might be different than midrange/treble. So the initial measurements might point you into w
  5. I couldn't agree more. I also got it because of Mitch's early articles in this forum, and have gone from 2-channel to now 8-channel active stereo and Acourate is the centerpiece. I admit I have not gone beyond what Mitch covers in his book though. I am intrigued about the situation you mentioned, quoted above. I'm aware of Uli's thread on VBA, where 4 subs mounted on the front wall are needed and 2 are well above ground level. Do you have such a setup? I'm intrigued because I have 2 subs against the front wall (on the floor) and assumed that in order to apply the VBA approach I nee
  6. Wanted to ask you about the purpose of the OpticalModule in-between eRs. Why do this vs fiber from eR1 to eR2? Which "LPS3" do you use to power eR+cable modem? Regards
  7. Thanks for reporting. I understand your eRs are connected through copper cable now. Have you tried using fiber between them? I also decided for a second eR instead of an OM, and interested in how material the link between both might be (fiber vs ethernet).
  8. Thanks for reporting this. My recollection is you were running 2 eR in series both with the supplied SMPS, and that you have tested the 2 eRs vs 1 eR with LPS 1.2. Have you tested the LPS on 2nd eR vs the 3 eRs?
  9. I was thinking along the same lines: maybe upstream network optimization are key difference amongst users and affects the ressuts? I remember MartinT mentioned his upstream network was optimized (LPS for router, etc), and my recollection from Rsbrsvp is that he didn't. Could it be that DX is filtering out high frequency components injected by mediocre SMPS upstream (like from the router), so if you don't have such SMPS to start with then you are better off? If that were the case the DX would be a much cheaper way to chean that noise than an LPS for the router, provided there is at
  10. yes, I've read the paper and followed the comments about minicircuits. Unfortunately some weeks before John published the paper I had purchased the BG7BTL with square waves only . My recollection is DarqueKnight measured the BG7BTL square waves with different 75ohm cables and one that came with a unit (a DCS?) measured well despite being cheap. Some have reported good results with BG7BTL square waves, so I'm checking in Ghent makes suitable cables as I will be ordering a couple other cables from them.
  11. Does anybody know/measured if the Ghent E07 Belden 1694A BNC 75Ω Coax Cable is a genuine 75 Ohm, good cable for BG7BTL?
  12. Thank you John! By "fast" you mean DSD 512 or 256, etc, right? Would DSD 256 be 12Mbps, so 4 would be about 48Mbps and maybe enough for B-side?
  13. Since we have touched on the 1Gb vs 100Mb topic, I wanted to ask for opinions of a setup I've been chewing on: I do 4-way active stereo, so 8 channels, digital crossovers. I have my eye on Merging Hapi, that is well known for sound, especially over DSD, and uses Ravenna. I found one person using Hapi and eR, who confirmed Hapi wouldn't run out of eR B-side - no surprise. He used two ports on the A-side, which obviously isn't best. 1) Does anybody have an educated guess if this would work: have eR1 receive on A-side, output through B-side connecting to eR2 A-side where Hapi will als
  14. For those who tried/preferred Ghent, what's the recommended criteria to choose between ET11 (CAT6a) and ET12 (CAT8)? Other than stiffness of ET12. To use on B-side of eR. Current is generic CAT7, so either should be a significant improvement (at least that is my expectation!).
