Title: headphone amplifier
Post by: doog on 25 April 2010, 16:12:39
Is there anyone on here that can recommend a decent headphone amp. 
Im getting pissed off with all my devices being unable to drive my headphones properly.

probably impedances are different  ..

I tried many before purchase..

most of the earphones were weak in noise..

finally bought sony mdr-xb300 .. well pleased with it..

both with pc and other systems..

TRy these, I use a set with my Creative Zen MP3 player. Plenty of 'noise'!

ive tried quite a few sets of headphones in the lower end of the price range  and  been unhappy with the results.
 I need a headphone amp because the ones i use are not the easiest to drive  :y

I was trying to listen to music on my pc and its just rubbish

this is the set i use at home

I think it's probably a hearing aid you need, not headphones.

I got a set of Shure in-ear things (needed them to travel with) and have to say they're excellent.  They fit so snugly and block out so much ezternalnoise I've nearly missed two fire drills at work, and if I hadn't noticed the office emptying I would have been none the wiser, because as far as I was concerned the music was great :).     I spent a while choosing but I've had quite a bit of shure kit before and never been disappointed, and the reviews were very favourable.  Not something people are that happy letting you try before you buy though.

I just built my own....based around a good opamp biased to work in class A mode with a quasi complimentary transistor output.

Works quite well

Simples.

I use a good opamp to work as the driver for the pwoer stage.

This opamp has the output loaded such that it is forced to work as a class A amp (the optimum amp design).

The output of this then drives 2 transistors of the same type (both N-Type) arranged as a quasi complimentary pair.

This give the drive to run the headphones.

A bit more info. about what you need would be good. What devices are you using as a source, and what headphones? Do you need something portable that you can take jogging with your Ipod or something mains powered for listening at home?

What are the problems you are currently having? Just poor volume level?

Stand alone headphone amplifiers are a great idea if you spend a bit of time listening with headphones as, at the low power levels involved, you can make a much less compromised amplifier than if you also require it to drive speakers, where a class A amplifier of any useful power level will double as an effective room heater and wallet emptier!
