Small resistor in series can help for damping out the humming?
It can be tried.

Hey MalVeaux
This is indeed an innovative solution for using a lot of other headphones with a speaker amp! As others have said, thanks for thinking of this!
On the Meridian Explorer thread, it was suggested that a 6 dB line-level attenuator could be used to solve one user's problem.
I just found a 12 dB version of that same product:
I'm not sure which approach would give the best results - attenuating at the amplifier's input vs. at the output, but it's something to consider.
Harrison makes 3-, 6-, and 12-dB versions that look like this.

So maybe I'm missing something...but I've got my setup (minus the pre amp) and the volume gets to about 11 on the emotiva..with my source usually around 90-95%.
IMO - your source should be at 100% What's missing?

just curious, but what is the reasoning behind having source at 100% as opposed to having it at around 25% and letting the amp pick up the slack ?
I think I might have figured out the hiss/hum problem that some people have been experiencing with HE-500. I think it's the cables that cause the hum.
So before with HE-500, I got a balanced cable and a XLR to banana plugs adapter. Both of these cables were silver and from Headphone Lounge. Absolutely dead.
Today I got my LCD-2's back and I'm using the stock balanced cables from Audeze to connect them to the previous adapter. With volume turned down all the way, I noticed some noise. At first when I used the LCD-2, I found the pure blackness of LCD-2 to have somewhat diminished. That's when I noticed the hum. With the music playing at around 9 o clock, I am not hearing the hum, and it sounds quite good. Although it's not as black as I am used to with something like the O2 or Emotiva with HE-500 (all silver cables).
So your saying if I want to completely eliminate my noise/hum I will need a pure silver banana plugs - XLR ?
what about a pure silver banana plugs - female TRS
hmm, alot of money to spend for something that might not even work
This is getting ridiculous. 2 years ago when I joined I was going to run my HD800's on the speaker taps of a mini EL84 tube amp I purchased for my Stax electrets at the time. I read from a lot of places including diyaudio that running it off speaker amp's can either 1. damage the headphones transducer due to overload, 2. blow the transformer on the amp due to the inefficiency link between the headphones itself and the integrated amp powering them, this can be fixed by using a dummy load adapter. It's true that certain speaker amp's can be designed to intake headphone outputs just by matching a resistor to balance the load but is it safe still? It's a fair enough point driving extremely hard to drive inefficient headphones such as the K1000, HE-6 or other beastly orthos, but even with 500ohm impedence adapter's for D5k's and SR-80's I think that is no where near the safe point of driving them without degrading some part of the amp or headphones as those load's are not even close to what the HE-6 and K1000's can take.
seriously?What makes you think a headphone amp and speaker amp are inherently different (serious mechanical stand point question)?
Legit questions, not trying to be rude here.
Very best,
