I just rolled w/the name.  lol  Didn't realize you were from Omaha.  Great lil town once you get out of downtown.  That place was crazy years ago.  lol

 

A delicious monster rabbit!

All it needs is a nice warm marinara bath and to be made all comfy in a warm blanket of pasta. 😈

Since the day damnitt janet and that blonde top40 floozie cussed and talked about blowing something up?

 

Then they tell me I have got to cross my legs? 

 

Ugh NO!

 

I've felt they should put it up for the ones that pay their way, not me but you get it!

Not since and never again for those vile hate....

How about everyone just have situational awareness instead of trivial spats?  Who here walks right into a dog turd rather than watch where they are going?  Of course there is always common courtesy, or is there?

Of course there is! For family... but I don't have any anymore.

For strangers, yes also. But don't normally have strangers over since my early thirties.

 

For the two that wanted to blow up those full grandstands on one of the USA's most special days. Plus she wanted the White House obliterated also!

They do not deserve courtesy, they squandered it.

 

Does that clear things up?

Maybe you never saw that video played back on that day. I won't ever forget. Might forget those gals though.

Wasn't aware a statement qualified as a spat!

 

Seat's up, all the time!

Quick cable question. 

 

When I have no cable plugged into the source side of the keystone jack, meaning just the supply side (in the first picture, it's just the blue RCA). There is little to no hum until around 60 on thr volume setting

 

Once I plug in a cable on the source side with or without a source(black one in second picture) I start to get a hum around 53 and even a faint but odd ticking sound.  

 

Update, hum is gone when source is plugged in. Just have the weird ticking sound.

 

Any idea?

Truthfully I have no idea what or whom you are referring to.  As for a spat it wasnt a comment on a statement but a comment on the sillyness of the topic.

@The Dude ouch, chasing hum. There are a lot of things out there to diagnose with much better results, but ... yeah.. gotta chase it down. I can only offer one suggestion here, which is shorting plugs. Make up a set of RCA plugs that are shorted (AT) the plug, as short as possible to the plug body. Using RCA barrels for cable testing, or just the plug at the amplifier inputs. Start at the amplifier, shorting the input and note the level of volume of hum on the volume knob, hopefully almost zero at full volume. Using the plugs with the barrels, one cable at a time one end plugged into that input, the other end shorting plug, note the level of him then on the volume control, again it "Should" be almost zero, but depending on the shielding there might be an increase. Once you know these things, then your source (CD, TAPE, DAC) plugged in to the same, and or through known cable of silence, if there is hum, then it may be within the source or the source cables. Now to make things more confusing, it is possible that is not the case, and just tuning the power cord around in the receptacle could make things better or worse. Opening the dreaded chase of ground loops. It sounds like you are speaking of the inclusion of a cable here increases the hum you hear, which may be shielding problems in that cable.

If you connect a cable to an input and just let it lay there open ended (no shorting plugs) you should get hum, as the cable is now acting like an antenna to the magnetic fields in your listening area. but shorting the cable should eliminate that hum unless the shielding is poor or broken. Keep in mind that a piece of equipment "IS" an antenna in itself, so the manufacturing engineering should have already resolved that with equipment grounding. I must talk safety here as well, since I suggest reversing the AC input to equipment, if it is 3 prong grounded then do NOT change that no matter what. Doing so "COULD" depending on what receptacles being used present 230 Volts between the 2 different sockets. (Opposed phase USA wiring for homes)

I have experienced using perfectly silent cables to hook up device cause terrible hum, and changing to a different cable reduces the hum, and that same cable that hums is perfectly silent on a different device. In that case it was the capacitance and inductance of that cable was not a good fit for the one device.  So many things that will cause or solve the problem of hum. I wish you Luck and SUCCESS here in the chase. PM me if you wish and it shall be good to have the resolution posted here for others to ponder as they enter the chase.

Point of interest in this as I have been chasing down a hum here, and I finally found the source of the hum, and was not a cable (I thought it had to be one breaking down) but my cassette deck, just being plugged in was the cause, so the device will need repaired. This hum was being caused by old capacitors inside that are across the AC breaking down. I found this by a symptom of brushing my hand across the device I felt that famous electric buzzing.

I hope this is helpful and good luck!

I realized after posting that this was the case. Only issue I am dealing with now is the odd clicking sound.

Clicking the clocking emitted from dAc ?

It would have to be from the AVR as the clicking sound occurs regardless if there is a  source is connected or not and only after the additional pair of cables are attached. 

 

FYI, the source is a Turntable, Dual 1019.  But I didn't think it was relevant as the clicking occurs even when its disconnected.
