| 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... | |
| Isolating Digital Noise, need help. @jea48, so far there is no high-pitched noise when using the stock PC on the ARC. Perhaps the Audience PC is not a good design for a digital device?The stock PC sounds pretty good thru my power conditioner, but lacks the open soundstaging and dept... | |
| Isolating Digital Noise, need help. jond, I've had to use the cheater on the preamp from the beginning due to 60Hz hum. Spoke to Ralph at Atma-Sphere and Almarg and the problem is due to ground loop thru unbalanced cables.The Jensen Iso-Max didn't work on the preamp, there was still... | |
| Isolating Digital Noise, need help. @xti16, good question. I am hearing this noise since I added a new preamp (Atma-Sphere UV-1) which is much more transparent than the previous one and has higher gain. What's interesting is that it is so resolving, I can hear the change in noise fr... | |
| Best Way to Spend ~ $2000 for System Improvement @xrayz, You're right about the average electrician, they don't understand the complexities of power in an audio system. Mine said he knew all about home theater and not to worry. He was competent, but in the end his installation was not optimal fo... | |
| PrimaLuna cable needs Have you auditioned the PrimaLuna with the Triton Two's? They appear to be an efficient speaker; 91dB, 8 ohms. But to drive the subwoofer satisfactorily, these speakers require some power.It would be wise to use KT120 or KT150 tubes to get the mos... | |
| Best Way to Spend ~ $2000 for System Improvement @xrayz, 6 years ago, an electrician charged me $210 to install a 20 amp breaker and run 12 gauge Romex from my basement panel to the 1st floor. I've since learned that 10 gauge is recommended and that I really needed 2 dedicated lines. Running two... | |
| Internet music sellers All the Internet vinyl retailers have raised their prices. Soundstage Direct and Music Direct are now too expensive for LP reissues that are of inconsistent sound quality.What are the Audiophile sites that you are referring to? |
