    Was thinking he should try the same thing too.

    But apparently the TV didn't produce any static, static only when the Candela was in the mix.

    So - looks like it's probably the Candela.

    But maybe something with the Shanling too?

    I dunno ---

    Outlaw will be back in a week or so...

    Will hook it up then and see what happens...

    Static remains -- fingers go back to the Paradigm or Shanling...

    But oddly enough, the stock Candela tubes are flat out awesome -- much clearer than the other tubes I had...

    It may just be a combination of the Candela, Paradigm, or Shanling.

    Since Shanling -> any amp produces static, and

    Candela -> Stratos Monos produces static too.

    If it were the Paradigm, then it doesn't explain why the Shanling is producing static when fed directly into any amp.

    If I understand correctly, that's bypassing the Paradigm from the chain.

    But you also said when the Shanling was unplugged from the Candela, the static still persisted.

    So if the Shanling is not even plugged up, how could it be producing static?

    Hmm...

    This makes no sense

    But so can a bottle of Jack and a big fatty.

    I tend to believe your problem is the later.

    I'm not sure what the cause is --

    Will know more once the Outlaw returns so I can try a different preamp -- if it persists, will have to track down a cheap DVDP to plug up in place of the Shanling...

    As for a source, save your loot. Gee whiz, I have plenty of gear I can loan you to help you figure this out. I'm in Matthews almost everyday, so maybe we can work something out. Kuul?

    Trust me tonyb, it's not that.

    Also, can you get a cheap DVDP from CC or BB or Wal-Mart just for testing purposes?

    I have a $20 DVDP - analog out is pretty good, no buzz. Nowhere near the quality of my Onkyo, but still, for $20, the sound quality is good.

    Long shot. Have you checked any of the suspect equipment for a loose chassis ground? Something that could possibly introduce noise through the power TX's? Loops?
    Just a thought.

    Was thinking the same thing too.

    Trey - do you plug all your audio gear into the same phase on your circuit breaker?

    But I'm still suspecting it's the Shanling, Candela, or Paradigm. Or any combination of the above.

    That will allow me to test out the preamp --

    Plenty of cheapy DVDPs around here to put into the loop...

    Thanks for the offer though broham

    After working on the system for... 6 hours troubleshooting --

    I was in the mood to just tear everything apart and do some new wire managment to go around with the PC --- much MUCH easier to manage my cables now...


    Well after looking at the picture you posted, the problem is pretty obvious and it is actually two-fold. First, that little deer figurine in the corner is picking up stray RF signals and sending it to straight to the tubes. Secondly, that little toy figure at the bottom right is aiming it's laser weapon straight at your gear, causing the static you are complaining about.

    No, it's the light bulbs in his ceiling fan. Just replace them and you'll be fine.

    Actually, the static is due to your neighbor's new wireless router.

    Well - Outlaw came in today, quickly hooked it up using the Candela's HT bypass

    And something is seriously effed in my Candela -

    Using the HT bypass, you should have to select it to HT to hear the Outlaw --

    Not the case, I could hear it on every single input, at half volume...

    If I turn off the Outlaw, my volume on CD is shut in half...

    So I called Klaus - Mike was there, no Klaus... awaiting Klaus to call back...

    Ah well...

    Preamp troubles in Sidland..

    But Outlaw is rock solid, repaired the 990 in about 2.5 weeks, paid for shipping back --- repaired it for free --- and threw in a pack of playing cards...

    Awesome stuff
