[Inexpensive, but decent, CD transport with AES/EBU]

The Delta is a nice transport. Don't let the textured blah Black look fool you. The money is put into the SQ, and not flashy trim.

What did I tell you about the lols...

lol, he was so giddy lol, what with the new TeenBeat coming out and such lol, that he just lol forgot lol.

[New Cat]

get one of these monsters, too:

That will be my next cat. They're so damn ugly they're cool. If they just didn't cost so damn much!

[Let's Talk Power]

I have a dedicated circuit in my little studio, and I use a TICE Audio MBF-3 power conditioner. Very fitting I thought since Tice is my last name as well.

I know it well, nice snag buddy!

[Post the last thing you bought!]

This one?

[Post the last thing you bought!]

Vince buddy, He's probably seen your email and is replying, but with all those extra U's they put in their words like colour and flavour, it takes much longer to type out a reply.

[Fake headphone stands]

Oh, OK I'm on board.

[Fake headphone stands]

What was this thread about again?

[Is the 4 pin XLR wiring configuration a standard?]

I'm not so sure there is an industry standard though.

[I'm an asshat]

Does it come with roofies?

Hehe this is me not liking something:

Biggie.

LOL!

[Who likes the R10's?]

Poor people like me can only dream of hearing a pair at a meet some day.

[Balancing a vinyl rig]

I tried the cheater plug on the speakers, but not on the subs. I'll try that later.

[Balancing a vinyl rig]

I just remembered I'm babysitting some long SE ICs for plaidplatypus. I hooked 'em up and the buzz returned.

[Balancing a vinyl rig]

Uhm no I haven't tried it. I don't have any SE ICs. But my buddy Scott will take it easy on me.

[Balancing a vinyl rig]

Yes absolutely. The PCA-2 has 2 sets of SE outputs as well, and the subs have RCA inputs too. I'll get Scott to make me some SE ICs. Thanks for your help!

[Inexpensive, but decent, CD transport with AES/EBU]

Yeah buddy! A Bloodwood overlay would be sweet!

[Balancing a vinyl rig]

try unplugging one of the PCA-2's balanced outputs

Marc whatever you were thinking was right, the buzzing stops when I unplug the subwoofers from the PCA-2's second pair of balanced outputs.

What does this mean, and will I need to leave my subs unplugged until I want to listen to them? In any case that's far more simple for me.

[Inexpensive, but decent, CD transport with AES/EBU]

I would think that putting your money into a pure transport instead of a CDP will usually warrant you a better transport. I can highly recommend the HiFiDIY transport. If Renato has the time to put it together you just can't do any better for $400.00.

[Balancing a vinyl rig]

One possibility would be to never turn off your pre. Does it have a mute? Does it buzz when you mute?

It does have a mute, and it still buzzes with mute on when the volume is at zero.

[Balancing a vinyl rig]

I'm confused -- you're shutting off your preamp, which is part of...your speaker rig? And hearing buzz...in your headphone rig? Do me a favor, please, start over -- source, pre, amp, speakers, headphone amp, headphones, where do the two chains split, what are you shutting off. (I also want to look up input and output impedances, where the information is available.)

Source:

HifiDIY CD Transport/Zapfiltered Twisted Pear Audio Opus DAC

Preamp:

PS Audio PCA-2

Amp/Speakers:

Paradigm Reference Active 20 (built in amps) and AV123 Rocket UFW-10 powered subwoofers (2)

Headphone Amp:

4 Channel Balanced β22 w/dual sigma22s in separate case

Headphones:

Modded AKG K340, Modded AKG K240 Sextette, Chocolate Donuts (Modded Yamaha YH-100 Orthodynamic drivers in custom wooden housings), Modded Sennheiser HD 580. All phones are cabled balanced

The chain is as follows...

The CD transport digital coax output is connected to the digital coax input of the Opus DAC. The Opus DAC balanced outputs are connected to the β22 balanced inputs. The β22 balanced outputs are connected to the PCA-2 balanced inputs. One pair of the PCA-2's balanced outputs are connected to the Paradigm Active 20's balanced inputs. The other pair of the PCA-2's balanced outputs are connected to the pair of AV123 Rocket UFW-10's balanced inputs.

I hear no buzz or ground loop through any of the headphones. I also hear no buzz or ground loop through the subwoofers. The only place I hear the buzz is through the speakers, and then it's only when the preamp is set on zero volume (where it automatically is set upon startup), or when I turn the preamp off (the speakers are always left on, but only power up upon receiving an input signal, same for the subwoofers).

The PS Audio PCA-2 does have some unique features, for example the active volume control. I'll link PS Audio's PCA-2 info page for reference.

I'm not sure how I'd determine this, you're talking to a complete simpleton when it comes to electronics. And would there be an easy fix in either case?

[Balancing a vinyl rig]

Yes I think powering off the preamp (PS Audio PCA-2) is effectively the same as dropping the volume to zero.

[Balancing a vinyl rig]

Well the 3-2 prong converters on the speaker power cords don't help either. As I stated, if I turn the volume dial to even 1 the hum goeas away, but after I shut down my gear it comes back, and I have to disconnect my speakers. It's kind of a pain. Any other ideas?
