OK.
As a junior member I am supposed to still learn
...and I will set the example.
I have had it with these expensive headphone amplifiers.
(The price of this one was not quoted but I can imagine by the looks.) Will someone kindly broaden my horizons and inform me why a headphone, requiring no more than the lofty output power of say 1 - 2W (unless you are so deaf that you should really be going to a live performance and lip-read the performers and their instruments), should require an electronic driving device, the more exotic models of which cost more than some quite decent stereo power amps ?? Is this even worse than cables?
I saw some circuits on other forums capable of some tens of watts, and someone even suggested that now that we have digital chips, those could be used to keep the size down (guess it was an oversight not to also mention keeping the heat down). I am delusional enough to still simply just use my main amp. - with a suitable output attenuator to get slightly away from the bottom 10% of the volume control (I switch the loudspeakers out). I can also understand that that might sometimes not be an option and a separate unit might be desired. But apart from that I see no reason why the simplest of decent low power circuits could not be used. From what I know about headphones (cheap and high-end) they are usually around 25 - 100 ohm impedance, etc. I have Sennheisers and they sound perfectly good this way, as do a number of other well-known brands.
So.
Regards.
