You might also consider a power regenerator from PS Audio (like the P600), which converts your home's AC power into DC and then re-generates it as AC with perfect sine waves (or something like that...check out their website for details). From what I've read, no power conditioner (including the expensive highly-touted ones) can clean a signal to the purity of the one that the PS Audio units generate, because (since they are just fancy filters) they still rely on the power being well generated (by your power compnay, I suppose).
XLR cables are picking up radio/TV hash...
Hi everyone,
This is an ongoing dilemma so I'll try my best to be short and to the point. I recently got 1 m Cardas Neutral Reference XLR to use between my Sim Audio W-5 power amp and my Marsh P2000b preamp. My system sounds a lot better, but I am picking up audible radio and/or television sounds on my speakers (Quad 22l). I do not have a functioning cable tv connection (I don't have a television, period!) but my power outlet is near a cable tv jack. Could this be the problem? I read on some other fourm that the cable connection may need to be grounded.
I have tried to go troubleshoot in a thorough fashion; I tried using cheat plugs; I disconnected all my cables, power cords and speaker wires, then reconnected them slowly. I discovered that only when I powered up my preamp did I got noise...and it did not increase or decrease whatever I did with the volume knob. Something is obviously acting as an antenna and picking up signals.
I think this may be a problem unique to the Sim Audio W-5; it has two sets of RCA connections, where, if you choose you can use both sets in a sort of single-ended "balanced" configuration. There are two dummy plugs inserted into the negative inputs, and the positive inputs are used in a normal single ended configuration. Thing is, I had no noise when using the Marsh and the Moon in single ended mode. I am certain that my new Cardas cables are fine...I had them checked out at a dealer...I also replaced them with a brand new pair of Transparent balanced cables with the same resultant hash. I did find that if I placed the two dummy plugs into either the left or right set of RCA connections I did not get any hash on that channel but it obviously degraded sound quality as it shorted out that particular channel.
I have had suggestions ranging from changing my preamp with another balanced one to check to see if that is having problems, to using Cardas caps to cover unused XLR and RCA connections, and even clamping ferrite clamps on the XLR interconnects.
Also, I am using a Rega Planet 2000 (in single ended config) and a Rega Planar 3 with a Pro-ject Phono Box SE; I am pretty sure they are not the cause of my problems but I am just being thorough for the record!!
Please help!
Thanks,
Khalid
