    Trey, I have a pre right up in your area....probably within 12 miles from you that a buddy of mine is no longer using. PM me if interested. As for the source, does your mom have a VCR or something in the LR that you can use? Or, could you not use the game station [whatever it is???] as a source?

    I hate this for you!

    Let me just throw this out there to you guys as I am just... bewildered at this point...

    Monos + Candela + Speakers = noise

    Monos + Shanling + Speakers + Nothing Playing (Stopped) = No Noise

    Monos + Shanling + Speakers + Something Playing = HOLY EFFING JESUS CHRIST'S SISTER IN HOLY JOSEPH I'M ABOUT TO BE KILLED NOISE

    It seems like literally, my Preamp, CDP, and Crossover have been FRIED?????

    W-T-F

    Just a thought -

    A while back you said that you bridged two channels on the Shanling to form one big channel for a sub. Shorting together two channels on the CDP might have done something to the CDP.

    I don't imagine that would be it, because the sound out of the Shanling was better than that of the Rega Apollo, at least with the analog outputs.

    Trey, can you use your computer as a source?

    I highly doubt it ---

    If that were the case, it would have been an immediate thing...

    I'm going to get an 1/8" cable from a friend to plug up my zune directly to the Mono Blocks and solve this BS once and for all

    But I don't remember which outputs he bridged together. All I think I remember is two things were bridged together with a Y-adapter.

    Hmmm, that might explain why the tube output bit.

    Ok...

    So I changed the tubes...

    And it actually got worse....

    Odd --

    Go from there ---

    Totally disconnect the pre...

    Attach the CDP directly to the amp...

    When a CD is NOT playing -- it is kind of quiet, a very slight static...

    When a CD is playing, all hell breaks loose...

    I'm starting to point fingers at the Mono Blocks...
    Could it be that you have a bad set of secondary tubes?

    Everything that you have mentioned on this thread involves the tubes being in the path of the end result. Common denominator type of thing, you know?

    You got Deoxit? Try the contacts for the tubes.

    Which output off the CDP did ja' use?

    What I think - bridging the CDP's L/R outputs did not have an immediate effect, but it might've done something to the CDP's output. Over time, this affected the Candela and that signal got passed onto the monos.

    I say this from experience, because when I was 11 the same thing happened to me when I bridged the outputs of a VCR. Didn't happen immediately, but in the middle of playback one day a LOT of static came out of the speakers (the VCR which was connected to a TV, and the TV's audio out was connected to a boombox.) Result: the TV's left channel and both tweeters on the boombox were fried.

    When I bridged the outputs on the Shanling - it was the SS outputs

    At the time I had just received the Shanling and thought the SS outputs were inferior

    Not the problem

    Got the Zune --

    Plugged directly into Mono Blocks ---- No static or anything, zero issues

    I just unplugged them from my new found power conditioner

    SAME EFFING PROBLEM
    Plug everything back the way it was before the power conditioner. I know, I know, I know. "Whatever".

    Try it anyway.

    So your mono blocks are fine.

    Are the SS outputs on the Shanling the ones producing the static?

    So, the speak's, x-over and Mono's check a clear bill of health......

    I tried the Tube outputs - same thing with it...

    Reintroduced the Paradigm X 30 between the Zune and Extremes --

    A SLIGHT static -- which is what I had BEFORE all this chaos started and am use to -- so the Paradigm X-30 is NOT causing this problem....

    OK -- so now on to the big bad Candela back into the mix with the Zune as a source...

    OK, so if that works, then

    Zune -> Candela -> Mono Blocks?

    I dont know guys ---

    This makes no sense...

    I tie the Candela back in and I get static... - its not loud and obnoxious... but its static none the less...

    And I can't think of anything thats changed...

    The ONLY thing that comes to my mind that would do ANYTHING like this would be the fact we turned on the heat recently vs. the AC -- but I can't imagine this causing an increase in static...

    So at least we know the mono blocks, crossover, and speakers are fine.

    You don't have another preamp, but you can use the TV as a preamp.

    How about...

    Zune -> TV -> Mono Blocks?

    And what kind of heating system?

    Remove the tubes from your CDP they aren't needed for SS anyway. A tube may be still the noisemaker. It is usually the problem when I experience an increase in noise in my system.

    If that isn't the issue, then the Candela tubes got to go........that was your first thought early this morning wasn't it? Tapping the preamp made noise.

    I think its the preamp guys....

    I added the Shanling back into the mix -- playing it right now

    The Static did not increase

    Something about the Candela picking up SOMETHING -- what something is... is beyond me....

    *sigh*

    But we are getting somewhere...

    You may be getting some kind of funky **** when you added the PC. I have in the past.

    2 things changed right? Heat/AC and the PC. If you had the vid on one outlet and the audio on another...

    Yes, that brings up something.

    When I had my video stuff on one circuit and my audio on another, I had a ground loop that could be heard only when my furnace kicked in. I repeat, ONLY when the furnace kicked in.

    Trey - Remember I had e-mailed you about grounding and noise from my sub?

    Right now -- just to give you the run down on whats running through the PC as of right now....

    Running through the PC -

    Paradigm, TV, XBox, Shanling (I'm pretty sure thats it)

    And to make sure its not the PC, I put the Candela, and Monos on the outlet behind my rack...

    I had the Candela running on a side outlet --- but the static persisted, switched it to the front outlet on the PC, and the noise continued...

    Not sure if that eliminates the PC or not...

    And the static did not cut out any at all....

    Eliminate the PC and see.

    But I'm thinking it's like the ground loop issue I had - it only showed up in certain situations...

    Well --

    I'm just going to deal with the static for now...

    Just turn off the Candela at night and call it a day....

    Some reason Klaus isnt answering his phone the past 5 hours I've been pulling my hair -- so I'll call him again tommorow and see what he thinks...

    Just to freaking WEIRD
