Would a bad tube cause a buzz?

Serendipity

For the third time, did you do the TV thing?

CDP -> TV -> Monos

Would help to rule some things out, since the TV's output (in mV) may show something...

Serendipity

Why I keep saying the TV -

Has something to do with the fact that no two transistors are EXACTLY alike.

VR3

Alright - Update as we go along here...

Shanling - Direct to Crown, No Noise
TV - Direct to Crown, No Noise

Now am going to try some things direct to the Odyssey Monos - will return

VR3

Disregard Shanling statement --- it is causing Static when running direct to amps...

Good.

Transistors sometimes do weird things - I've seen this in my lab class before.

What? Static when connected to the Crown? Or Odyssey amps?

Let me see if I understand you correctly. When the Candela is connected to the Odyssey monos, there is static. But when the Shanling is connected directly to any amp, even the Crown, there is also static?

VR3

Ok --

If I set the Shanling volume to zero and plug it into either amp - I get static....

if I set the Shanling volume to max --- there is no static in the Crown, I can't do this with the Monos - or I wont have any ears left...

Then I'd think there is something wrong with your Shanling.

Can you connect the Shanling to the TV and then TV -> Monos?

Most TV's have internal circuitry for an internal amplifier that is always producing some gain, even when the TV's volume is turned to ZERO. So the internal circuitry has to be extremely quiet. For example, when I connected my TV *directly* to an Adcom GFA-535, I got no static regardless of the volume.

VR3

There are several consistencies with the static issues

And they make no freaking sense

All my components...

Shanling, Odyssey gear is staticier than HELL

Yet if I run the Shanling, volume set to max and the Crown gain set to half way ---- turn it on, hit pause, etc etc - NO STATIC issues...

Ah well...

I guess I'll just have to send some things to Klaus...

VR3

I dunno guys -

I'm confused... sooooo confused....

*sigh*

You need to run the Shanling again, volume set to ZERO, into the Crown and set the Crown gain at 100%.

There should be no static.

Serendipity

Wait: if your Shanling is producing static when run directly into either amp, then something is wrong with the Shanling.

Something else may be wrong with the monos, but the fact that there is static when you run the Shanling into the Crown is not normal.

Just ruling out things here...

I still think that you are simply amplifying some type of signal/power noise. Not really an issue with your gear, more of an environmental issue, some type of power drop/spike, wireless interference, etc.

Move gear, plug into different circuits, swap your DVD player into the source role, trip breakers, swap old ICs into the mix, anything that you can think of to change things up before shipping 100lbs back.

VR3

Ok --

I think I nailed the source...

I bypassed the Paradigm X30 -- Shanling direct into an Odyssey Mono ---

Absolutely NO static - PERIOD, at any volume level on the Shanling. Dead quiet actually ---


I put the Candela back into the chain, and there is a little bit of Static --- more than I think is acceptable -- but it looks like the Candela may be the culprit....

That's what I was thinking too.

But he said "TV - Direct to Crown, no noise" which gets me onto something.

There is no Candela in the signal path.

??????

You suck at explaining your chain, since the X30 just now shows up:rolleyes:.......get a simple chain going good then add gear one at a time. If the monos are ever clean, then something upstream is causing the noise.
You'll never make it in Pro audio unless you can x-ray vision a problem through the phone lines.........:D

Haha.

But the X30 wasn't in the chain when he went Shanling -> Crown. And he got static then.

No monos, no Candela, no X30 and there is still static?

VR3

Scratch everything I said --

I'm still confused, will be back in a bit...

He never said that........

Dennis Gardner

I think his frustration has him unthinking his problem. If that is a word.:D

Dennis Gardner wrote: »

OK, logically thinking...

When he connected the Candela to the monos, he got static. Without a CDP.

When he connected Shanling -> Crown, there was static.

When he connected TV -> Crown, no static.

So even if the Paradigm X30 was or wasn't in the signal chain, we still know that the TV did not produce static and the Shanling did.

I may be wrong.

VR3

Everything produces static

Static produces everything

I just don't EFFING KNOW!!!!! GOD!!! lol

Serendipity

Hold on a sec.

You clearly said the TV did not produce static when connected to an amp. Is that still the case?

treitz3

What change has recently happened that might have introduced this? Anything?

Dennis Gardner

I think he'll work through the issue and discover that it is one piece/IC causing the issue, and anything that amplifies the noise sounds bad, but it is simply upstream of his amps.

As has been stated, 2 mono amps will rarely go bad at the same time, but both will show up a bad piece upstream at the same time.

Dennis Gardner

Patience is a virtue that is yet to be found on his audio journey...........;)

BINGO.

It's probably something upstream. I think that's why the Shanling is producing noise on ANY amp.

VR3

Ok - just to throw this out there

Four cables (2 ICs, 2 speaker cables - had them for MONTHS)

Speakers, mono amps, Candela...

Put those together, I get static and bleed through of SOMETHING.....

I just unplugged them from my new found power conditioner

SAME EFFING PROBLEM

AND I DONT HAVE ANOTHER FREAKING SOURCE OR PREAMP TO PUT INTO THIS CHAIN!

I am going to sleep... If I don't... someone...something will die...

VR3

It looks like my Paradigm, Shanling, Candela is all F*CKED!

And with that, I give up for today -- I can't deal with it anymore... lol
