Headphone amp 4 Sennheiser HD555's

[GazzaFloyd]

On here way back from Asia my other half picked up a pair of Sennheiser HD555's from duityfree (she understands the Hifi obsession).

So the question is what would be a good Amp for them stats are as follows;
freq 15-28000Hz
input power 500mW
Impendance 120ohms

I am also instested if any one with Valve ideas would like to chime in.

thanks for your time

Gazza,

How do you find the HD555s? They have just arrived in .au but I'm having difficulty finding anyone who will let me listen before buying. Can you comment on how they compare to the HD580 or HD600?

Cheers

If you don't need voltage gain, the Szekeres is a nice amp, good sounding ans easy to build

i have had those 2 model's thay sound good. i find the open air
model's better. good hight's and not to much base. im using the hd500 now. i like that is has a plug on the speaker itself so if you
step on the cord it wont rip it out of the speaker-- see pic

and it's replaceable

yupz...the same as those I have on my HD490..I haven got around to replacing my aging 490s...but I kinda like them...so I;m sticking to em...cost me an arm and a leg at that time...when I was 13...used it primarily for gaming...everybody asks me the price of em after they've heard it...then gasps and sae "u're crazy"...yeah I am a little...but whu cares??

I can offer very little in the way of comparisen to the 500 or 600s I have run them for about 50hours and the show great prommise all ready the have nailed my Koss to the wall sound stage is amasing low end to die for and the hi's which were some what agressive are setteling down I am currently driving them with a QED can amp that is about 10years old

I am not sure if i need Gain

do you have any details on this amp

Also Heat dosnt scare me so Class A is an option

if you're using a 2V RMS output, believe me, you don't need voltage gain
