well,i made my own DIY cable and hooked my modded Koss KTX Pros to the (crap CSW computer speaker sets speaker out,3W each channel),and what i noticed was the IMMENSE amount of detail that was being given out.i played music through this babies for about half an hour and didnt notice any funny smell or something while they were blastint out !.
But there was a lot of hiss (probably because of the crap DAC).
Now should i connect my headphones to my Panasonic 50W RMS each Receiver ? These are powered by the TI5112 or so AMPS with 96db Dynamic Range and 52W RMS at 0.2%THD.

Should I ???

errr.. no

Koss earphones have... about 0.1w peak power capacity?

You'd blow them before you'd even gotten off of the bottom of the dial...

Definetly not advisable

Whahaha. That is hilarious. I would never do that. That would just ruin my headphones.

Explain to me how exactly they would BLOW up? what exactly will happen ?

try that and find out yourself

if you wanna try it on your receiver, play 1kHz sinewave from your computer, connect AC voltmeter on the outputs of your amp and carefully set the volume so that it gives you 1V, now you can connect your phones safely..

And please don't wear the cans during this test, or you'll need a new hobby.

The coils in the speakers will melt and split in 2. Sometimes the epoxy on the coils can heat up and melt off then the coils short and cause the coils to change impedance this can hurt the amp. They could smoke, when the coils short the speaker just goes dead.

Another thing ive seen is the coils heat up and the epoxy melts then the coils drag on the magnet and it sounds really bad. The sound isnt as tight and clean. You can push on the cone (larger speakers like a woofer) you can feel the coils dragging, it feels gritty.

And plastic surgery

Is that ear face?

depending on the impedence of your headphones, it might not hurt them at all. consider that the 50rms is at say, 4 ohms, and you 1/2 the power as you double impedence... so at 64+ohms its not much power at all.

a true square wave is guaranteed to permanently damage any speaker/headphone

At a hojillion decibels, sure, but I don't see how a 1k sine at listening volume could possibly hurt the headphones.

wow this is something I would do...lol

Back in my newbie audiophile wannabe days, I was a fool and plugged my Portapros into my dad's tuner amp @ 2/3rds volume... needless to say, I blew the left driver and possibly damaged the right in an instant lol. Luckily, I was able to exchange them for a new pair at Best Buy. My excuse was that they weren't working well when I first tried them. That incident just goes to show you how damn sensitive PPs are...
