I have no idea about what you are asking and I'm unable to measure anythin due I left that amp at my home town. If you really want I can arrange something. If I remember correct there I have some problems with oscillations, and I really can't tell what I do about that. Maybe I install some grid stoppers? Who knows. I might have some spare boards if you want.
But. That amp can't drive HD650. At least not for me.
Thanks for your offer, I'm not interested in the ECC88 boards.

I Finally got a chance today to test the HD650s with my DAC.

One of the excellent benefits of these headphones is that you can have two seperate cables with no common return (ground) which allows for connection to a balanced output.

The sound is excellent and hopefully will assist for future dac development.

I tried them also with my Rolland V-Drums just for fun... and i realised that my old senn HD485 are either busted or really poor...

Thanks again for you help

Hi. Sorry for late reply. Well about cables and burn in time. I use stock cable and can't tell anything about burn in time. It works fine for me from very first time. But again that's me. I somehow dislike ''audiophile'' way of thinking like something sounds bad but after burn in time it become great. I think that's not true. If it's not ok it won't become. And if there is any significant difference after burn in something is probably really badly designed.
I'm glad to hear you like your headphones. I know exactly why.

There is no such thing as cable burn-in. Don't believe them.

Agree! But of course somebody probably won't.

What you have should sound excellent right out of the box with no modifications of any kind. Just put some of your favorite tunes on, hit the play button and just listen

Anyway I get some information about Gyraf tube amp. I asked my brother and he has made some measurements. Voltages are always just before clipping with different loads and input voltages at 2kHz
in 0,5V, out 11,7V , open circuit
in 0,1V, out 1,8V, 680E load
in 0,06V, out 0,8V, 270E load
in 0,04V, out 0,3V, 100E load
in 0,03V, out 0,14V, 47E load
in 0,03V, out 0,1V, 33E load
in 0,25V, out 0,06V, 22E load
My advice, don't use it with some low Z Grados !
I used Russian 6N1P tubes.

I have both AKG and HD-650. No luck running both of them from most of my equipment unless I use my O2 amp. They are very different, I use AKG for more "attention listening" and the Senns for more fun. However the Grado 325i has something on both of these, specially in the mids (but not overhall).

My 701's and the O2 amp work very, very well isssues at all that i can perceive. The O2 designer choose the HD650's as his favorite set of cans in his blog site.
I have a set of LCD2's, the 701's and Grado 325is....all so different but all so good in many ways....

Good luck with your 650' me the cable upgrade is a waste of money..

All the best

Hi !

AKG is very hard to drive, isn't it ? you'll need a good amp for it.

EDIT : oops : didn't see there were 6 pages of posts ^^
