@mulveling "It reads like someone who's being supplied SR products specifically to complain about them." Yeah, typical aggressive audiophile-ism. When someone doesn't 110% agree with what a person has been told, they have to find some other way to bash another user. I find that this happens when such suggestions are actually wrong and they're too embarrassed to accept it, so they lash out.
But, just for posterity to others who might read this thread, I will address your specific concern:
"So the issue appears to be with the SR Foundation Cables. What's going on with these? They never presented a problem with other components that were using it. It seems to be limited to use on a record player. " <- I narrowed the scope to the issue being specific to the SR cable. That isn't brand bashing.
Now, the answer that has been given is that the cable isn't shielded for phonograph use. That is likely true and I don't deny that it's true. However, the "plastic turntable" doesn't require a phono-specific shielded cable to operate according to the instructions. That creates a dilemma. Sorry that it bothers you so much.
Issues with heavy noise using RCA cable connection to Record Player
Greetings,
I have a Denon DP-450 USB record player using the Ortofon 2M Red cartridge on a Yamaha TSR-7810. It was using old Audioquest (AQ) Ruby X3 RCA cables and there were no issues to speak of. I had a pair of Synergistic Research (SR) Foundation RCA interconnects that I wanted to try to use, so I switched out the AQ Ruby X3s. Suddenly, there is an extremely loud buzzing hum from both speakers that gets louder as you increase the volume.
I wasn't using the grounding pins, so I got a grounding cable and connected to both the player and receiver. That did nothing. I tried to see if it changed if the motor runs on the player, or if it goes away when music is actually playing, and tried to see if that noise happens on any other input on the receiver. I narrowed the scope to the phono jack. I decided to try a completely different cable and brought out my aging Monster Cable Reference 2 RCAs. No issues. No hum. No buzz. I went back to the AQ Ruby X3s and again, no issues. As soon as I put the SR Foundation cables, horrible buzz/humming noise again.
So the issue appears to be with the SR Foundation Cables. What's going on with these? They never presented a problem with other components that were using it. It seems to be limited to use on a record player. I tried seeing if I could find the answer out on the web, and the answers are perplexing at best. It could be a faulty cable, but as I said, it will play music through it and has no issues on other devices. The other issue could be capacitance? Apparently that is an important spec when using RCA cables on a record player. I am not sure what the AQ Ruby X3s and Monster Cable Reference 2 are doing differently. Is there something I am missing or haven't ruled out? Do I need to find an alternative method for grounding when using the SR Foundation cables?
Thanks in advance for assistance.

@kellydc3 I find it more amazing that folks such as yourself are incapable of helping anyone without first insulting them. "but, but, but, I didn't insult you!" Oh but you did, good sir: |
Why are you using something other than a phono cable? You do realize, that a the 2M red has an output of 5.5mV, right? You do realize your other components have an output between 1 and 2 Volts? So, your DAC has a signal 400 times stronger than the cartridge. Gee, I wonder why a cable may not be suited for a different use. Phono cables have to deal with that crazy low level signal, and needs to be shielded as ANY external electrical signals will cause noise in a cable not intended for phono use with appropriate shielding. 1 min of research would have provided you with that information. but instead, you decided to publicly shame a company because you don’t know how to use their product Not cool…
