Need help finding cause of hum
Hi Dan -- That sounds like a tough one. If I understand correctly, the problem developed after a long period of use of exactly the same setup without any hum. Given that, and given the rest of your description, the one thing that comes to mind wou... 
4 Ohm Speaker with an "8 Ohm Minimum" Reciever
A resistor is not a good solution. Besides wasting a lot of power, it will cause the frequency response of the speakers to deviate from flatness in proportion to the variations in the impedance vs. frequency curve of the speaker. It will also seve... 
Need help finding cause of hum
Al - Thanks for your reply. A lot to digest, but I'm thinking a ground loop isn't the cause. Wouldn't that cause hum in both channels? and at a higher volume? ALSO - I can hear the hum with only amp and speakers connected - no sources connected to... 
Bi-Amping without dual pre-amp outs
You are not cutting the line level feed in half. If the two power amps have equal input impedances, you are cutting the load impedance seen by the preamp in half. As long as the combined load impedance is still much higher than the preamp's output... 
Any issue with doing this?
Yes, that should work, assuming the line stage preamp provides sufficient gain (which I think most would). The only other concern which occurs to me is that sometimes hooking a tv system into an audio system, especially if the tv is fed via cable,... 
cart measurement vs quoted spec
It is an MC as I surely stated, all of 3.5$ of it.We also measure it by switching channels, and stepping up and down the alignments parameters mentioned AND using an SUT just to see. NO DIFFERENCE AT ALL!There is a resonant peak ~ 12dB --- can you... 
cart measurement vs quoted spec
Hi Axel -- Would I be correct in thinking that this is a moving magnet or moving iron cartridge? If it were a moving coil cartridge, perhaps the large ultrasonic resonant peak that would result from the 47K load would be a factor in these readings...

Need help finding cause of hum
Ghosthouse -- thanks for the clarification. You've gotten some good suggestions to pursue. I'll just add a couple of thoughts:1)If the problem is caused by magnetic field induction, I doubt that it would be induction into the speaker cables, due t... 
Need help finding cause of hum
Sounds like you've investigated pretty thoroughly and logically. But I'm not sure what is meant by this statement:When I reversed speaker placement (Right to Left & Left to Right) - cables staying in place - the hum stayed on the right coming ... 
Know anything about Pentagram Loudspeakers?
Some good additional background and information on the Pentagrams is provided in post no. 49 of this thread.Among many other things, he notes that the P10's were the reference speakers of a reviewer at "Audio" magazine.Regards,-- Al 
I'm beginning to wonder...
Nsgarch -- good points, very well put, especially your observations about those for whom English is not their first language.But I would qualify the statement about "free programs that can fix it all for you ...." to reflect the fact that the prog... 
pixelization?
In my previous post, the cable modem url I entered somehow wound up with an extraneous comma included at the end of the link, which causes it to not work. It should be http://192.168.100.1Regards,-- Al 
pixelization?
My only question is why does this only happen on HD channels? The SD channels of the same programs are fine. With no compression or equal compression, hd would require vastly greater bandwidth than sd, because of its far higher pixel count. There...

Compose in Word, spell-check, then post to Audiogon.Although it can sometimes be pretty comical when people over-rely on spell-check, and don't bother to proofread what they've written. Spelling and grammar checkers often will not flag an error in...
