Perfect!!

Holy crap!! That ranks up there with the ESP6 I restored and that was a crummy headphone from the 60's and not an R10.

I think it needs even more Duggeh... preferably one of your long signature posts.

I believe they use a similar type of panel as ML (powder coated sheet metal) so there are no dust covers and the drivers are often glued together. I'd start checking the bias supplies though before the panels.

Why ohh why can't I be in the states....

The 6. rule of HC, no lol crap here

If you have some sort of a volume pot and an enclosure then the only thing you need is some RCA jacks. The input goes to one pin of the pot, the output is the next one and then there is ground. It's even easier then pie... There there should be some passive pre kits on ebay...

I can't wait to get some for shoulder mounted headphones, the Surrounder Mk2... Has anybody seen any mention of a price of either the monitors or the sub unit?

I've compared a lot of transports and even built my own (Shigaclone) and they sound very different from one another. This isn't just limited to disk spinning units as USB transports aren't all the same and benefit from a better PSU.

I'm not sure how the NWO is designed but it shouldn't be a problem to simply ground the - output of the amp and only use the + which is SE. Have you tried XLR-RCA adapter plugs in the chain?

Yup, things will change dramatically once you move over to the closed baffle of planar headphones.

I really want a set to try out.

Sure aren't. The balls on those people not allowing their customers to pour thousands into "upgrades" which they don't need. Just wait until Mikhail hears of this and shows them the right way of selling headphone amps. They are also quick to deliver their amps. Those people sure have a lot to learn...

Mundorf Silver/Gold are maxed out. V-caps are maxed out. Jensen silver foil are maxed out. AN or Kondo caps are insane and you should be institutionalized. It is very easy to just fiddle about with the cap values to create some effect that is an improvement. I'm not doubting that better caps make a difference but you have to remeber what the caps are doing there in the first place...

Ahh the joys of buying used headphones from people that don't give a fuck... They could have tinkered with the cap values a bit to create a different sound. A change in the output caps would have a rather large impact on the sound...

I'd rather call you a soundstage junkie since you are willing to sacrifice everything for your fix.

I've had two here and heard no difference to speak of. The GES circuit could be modified by changing out the tubes (to something like the ES-1 uses) but I'm not sure if that will be enough of a change. You are still dealing with output caps which limit the output of the amp and certainly don't make the sound "better". A better option would be to get somebody to build an ES-1 (without all the patented Mikhail fuck-ups) or wait for the new DIY hybrid amp which is underway.

With the 007t the SR-007's bass is meh, overblown, muddy and lacks all the texture which the 007 does so well, but feed them well and they shine. Me thinks Tyll needs to spend some time with a properly setup 007 (the arcs will also have to be modified to fit his head) and see why we love them so much. I never liked the 6CA7's all that much with the O2's since the bass was too boomy and they did some strange things to the treble. They were a much better match to the He90 though but in the end I did change back to the Mullards due to their more linear bass and better tonality. The SR-404 frame plus the better glue which I use does bring about a slightly different sound which is more controlled. The earpads also change the bass quite a bit.

Both could work as Acoustat did both versions with their panels.

One question, has anybody ever stacked MMG's? They are a line source so it should give you moar bass and a custom frame which is wider should help even more due to the larger baffle. There is good reason for why the Maggies need some work done. I mean, who uses aluminum wires in speakers or indeed anything? I don't think that they are even allowed for use in in-wall power wiring here.

The set HE90/HEV90 sold for 15000DM which would be about 7500

It was 1991 for the HE90 and 1993 for the HE60 if I remeber correctly.

I've always wanted to try some of the PSE amps to see if they manage to sold onto some of the SET "magic" while giving more power and control.

Depends on the chassis and sinks used but my old unit very warm to the touch above the sinks and after an hour the whole amp was very warm. Not much of a problem here as we have plenty of cheap, cold air outside...

That does sound very interesting. Plenty of drive at least and all good tube choices. Are you starting to grow fond of parallel output tubes...? On another note I think it's time to try a SET amp with an output transformer just for. Given the needs of the SR-007 it will never be a good match but some of the other phones might like it. Should be dead simple to build and a good excuse to stock up on some 845's... The BH is definitely hot
