So what actually causes the hiss/noise when using a speaker amp with headphones?
Is it that the amp just has too much noise which becomes more obvious with headphones than with speakers.
Is it the typical high gain of the speaker amp magnifiing any noise in the system as a whole.
Or is it an impedance mismatch due to the amp driving much higher impedance loads than it is designed for.
Or is it another reason I have not even thought about or even a combination of the above.
I ask because I am also interested in a speaker/power amp for my headphones,especially but not specifically for the HE6's. I love the way they sound now out of my Master-6 so would not expect a 'cheap' amp to be better so I am looking for something a bit more adventurous and more expensive but I will also like to run other phones, especially LCD2's and very high impedance phones like HD800 and maybe T1's.
However I am concerned about noise levels & fine volume control. As anyone tried attenuators between pre and power amp?
The power amp I am looking at are rated @250 wpc into 8 ohms. I know people are going to say that it's total overkill, maybe even for the HE-6's, but if it sounds really good with no noise issues with a variety of phones then IMO it's no more overkill than $3000 - $4000 headphone amps.
I don't have any low impedance sensitive phones to worry about.
