Re: EndersShadow's setup

watch some of the online sellers that are nearby you- there is a frys electronics in my area that a friend scored 3 x 50" tv's for 399/ ea. they are no name brand, but are HD and they do not look nor work badly at all!

Yeah, I will do that.

I also have a pawn shop connection as well, so I may go look there to see whats around....

I am in no major rush.

Re: EndersShadow's setup

Ok, so I got the new rack yesterday and got it installed.

It was quite easy... but it normally is when you use child labor :smile:



Here are some in progress shots:

Starting to figure out what goes where:

Got it where I want, time to start wiring things...

Its final home:

And then the funny stuff....

I've been dealing with some sort of hum from my system since I put the B&K in. I attributed it to the processor whine I read about as it only really came on when the B&K was in sleep mode and the amp was still on.

I didn't notice it (I thought) when music was playing.

So after installing everything back in the noise got NOTICEABLE worse. I switched from XLR to RCA from the DacMagic and it got a "bit" better. Then I tried Coaxial direct into the B&K and it got even better. But its still there. Its noticeable when you hit those quiet peaks in songs or when one fades out and another back in.

I'd love some help diagnosing it better. Here is what I am wondering:

1. I have the B&K tied into the APC and the Parasound into the Furman. Could that be it? Both those units are plugged into the same outlet on the wall, but maybe thats what it is?
2. I've factory reset the B&K and basically have it setup to use "Stereo" with NO EQ, just have set crossovers thats it. Any suggestions from the folks with the Reference 50 much appreciated ( @mantis )

So for now I removed the DacMagic and am just trying a more pure signal path.

Here is what we have:

HTPC -> Black Cat Veloce Coaxial cable -> B&K Reference 50 -> Douglass Connection RCA -> Parasound HCA-1200ii -> Douglass Connection speaker cables (banana's on amp end, spades on speaker)

And to the way it looks now all said and done. The 3 pictures on the left were purchased by my wife from a friend. I still plan to get my wall treatments up and may use canvas w/ posters printed on them. Thinking something FireFly, Master Chief, and then maybe the famous hair blowing back in chair picture & Star Wars.....

Here are the internals of the computer. Its a custom build I've kept up with a bit over the years. I need to just buy a couple 3TB Hard drives to replace the 2 640's and 1TB I have in there now.

Re: EndersShadow's setup

Nice rack, Dan! :)

From what I've *read*, it sure acts like the infamous B&K processor whine.

For a cheap attempt at a fix, I'd suggest the longest cheapest RCA's you can find (50'?). Just bundle/stow them neatly. The extra capacitance of the long run will drop some of your theoretically audible highest frequencies, but more so the ultrasonic junk and resulting audible harmonics. Just consider it a tube buffer! :lol:

The Dacmagic Plus goes to 100kHz, so I could see even direct from the B&K into the Dacmagic possibly perpetuating whine. What model is your Dacmagic? Does it have any filtering options?

If your noise is hum from a ground loop, you know the drill. Start unplugging components one at a time until the noise changes. No guarantee that those receps are both wired the same or correctly, have you checked? I'd be leery of the powered sub- is it plugged into it's own recep, or one of the conditioners? Does changing that change the hum?

Yeah, thats kinda what I think it is... It just stinks its kinda there with low volume music (which is what I do a lot of here). If I didnt know what to listen to not a big deal, if I didnt sit less than 1 1/2 foot from the tweeter it wouldnt be noticeable... but well I do hehehehe...

Might try that later for giggles....

Its the original Azur DacMagic. Its got some filtering options that I've never played with but don't think they are the ones your thinking about...

Yeah I haven't done the total unplug as the second the B&K is off the noise is gone. Amp, Computer and sub still on. The sub is plugged into the APC. I unplugged it as well as the LFE cord and it still was making noise through the tweeters with all that done....

I haven't pulled the outlet but this noise wasnt present with my other diy pre-amp so I'm fairly certain its the B&K just weird the DacMagic causes it to get worse. Not sure if the XLR signal just makes it worse or what...

For now I'm just going to let it alone....
