| using large box dvd/cd/player as base for small tube amp If there are any vents on top of the CDP, you can’t put a board on top of it. With that said, components shouldn’t be directly stacked on top of each other due to vibration and interference, especially a tube amp. Components need to be isolated; t... | |
| Best Way to Spend ~ $2000 for System Improvement @xrayz, did you see my thread? I got advice from the experts on proper installation of dedicated lines, due to the fact my first installation was not optimal. The electrician did not arrange the circuit box for low noise.https://forum.audiogon.com... | |
| PrimaLuna cable needs Have you auditioned the Triton Two's and are they tube friendly? How did you decide on Nordost cables? Nordost is a forward sounding cable, were they recommended for these components? | |
| Isolating Digital Noise, need help. @tbg , no, amp is quiet.@jond, I'll try that today, the cable from the Furman may reach across the room.Thanks. | |
| Isolating Digital Noise, need help. I hooked up the Pangea PC to the ARC CDP and I'm getting the same high-pitched noise as with the Audience cable. After several A/B tests, there is noise when using the stock PC, but less audible than with aftermarket cables.So it leaves me to wond... | |
| Isolating Digital Noise, need help. @jea48, What does the meter indicate when both test probes are touched against one another? "L"? There in as "short" or "000.0", continuity?touching probes together shows 000.0 continuity. I made a mistake, it always indicates "0L" when there is ... | |
| Isolating Digital Noise, need help. Hi Al,Addressing the CDP high-pitched noise issue: You are correct. I will provide some further info;The CDP is connected to a more distant outlet... I used a heavy-duty extension cord with the Audience PC and ran it to a dedicated receptacle for ... | |
| Isolating Digital Noise, need help. @jea48 I did some tests on the amp. With my multi meter, measuring from the male ground pin on the Sunfire amp to the metal chassis of the amp, I could not get a reading of resistance. The meter indicated “L.”It is a digital meter with no multipli... | |
| Isolating Digital Noise, need help. jea, I didn't try the cheater on the amp. I didn't think it was a good idea to lift the ground since it is a high power/current amp.I will test the resistance on the Sunfire tomorrow, good idea. FYI, this amp was built in 1998 and has a fixed 3-pr... | |
| Isolating Digital Noise, need help. @jea48,First, thank you for the tip on checking continuity of the two cables. They both test with a beep using the Continuity Setting.Using the Resistance setting, both test close to zero.As far as my understanding of ground loop, when two devices... | |
| Isolating Digital Noise, need help. ptss, yes, using cheater plug on the Audience cable from ARC CD will get noise. | |
| Isolating Digital Noise, need help. jea, I hope that's a rhetorical question, because I'm going by what I read in the Whitlock paper.Ralph thinks my Sunfire amp may have an atypical grounding design. | |
| Isolating Digital Noise, need help. @jond, the output of the ARC is high; 2.7V unbalanced. But the Atma-Sphere has a switch for -6dB attenuation on the input.With the Audience PC, had the cheater on and off; still had the high-pitched noise.Stock cable, no cheater plug. | |
| Isolating Digital Noise, need help. @jea48, Beats me how you can get a ground loop hum from the AC mains safety equipment grounding conductor if only one AC mains system equipment ground is involved. It takes two tangle.There's been a miscommunication. When I referred to the groun... | |
| Isolating Digital Noise, need help. jond, yes, I’ve heard it the whole time. It took me a while to track down where it was coming from.I have excellent upper frequency hearing and there has been a constant high-pitched "whine" in my house whenever my system was powered up. I have ti... |
