...now we just need an electrostatic version.

You know I likes my HF on the soft side (SR-007 Mk1 ) but the distance from the drivers could be an issue. The felt on the back of the drivers is needed though to even out the sound so that could be a factor as well.

Happy birthday Justin.

I bought some resistors for the mini ES-1 project. Naturally there are no 5k trimpots to be found anywhere so I have to order them in...

That can be arranged.

The only problem I have with that description is that the SR-007A has its own midrange etch. \ I should get my 404LE soon so we'll see.

Hmmm voltage doubler, are you slumming a bit? Two serial connected PSU's sounds more like it...

What are you going to use the 300VAC for? It needs moar voltage...

Happy birthday!

Given how vastly inflated the Apache and B52 sales figures are I just assumed this was the usual BS that Ray spews.

I loved the BS about having 3000 pots that are of no use to him. Does anybody think that Ray has sold 3000 portable amps?

Ditto

Happy birthday!!

The only major change are the DC heaters for the tubes. The amp circuit is more of the same though they could have tweaked something along the way. I never looked that closely...

The last normal bias amps were made in August/September 2003 but the only change was to just replace the 6 pin socket with another 5 pin. This worked great on the 313 with only one Pro socket to begin with but the 006t and 007t were a bit silly. The 300 and 717 were never equipped with normal bias sockets since they were later additions.

We aren't really the normal Stax customers but many of us have a SRM-717 which is the best amp Stax has made in quite a while. The others aren't bad, just underwhelming.

There are also heatsinks which don't have any pins for screw mounting. I must say that I prefer the pins since it's never been a problem to remove sinks fitted with them.

Glad you like them Andy. The bass can even be a bit overwhelming at times but that's not surprising given the size of the drivers.

Well the bass out of the 007t sucks and if the fit of the headphone is off then it only makes matters worse. The bass on the SR-Omega is more rounded as it lacks the control and precision of the Mk1. This is a housing issue which is also somewhat present on my SR-Omega/007 hybrid. The soundstage is wider but the imaging is also more vague. It's not HE90 "I'm lost in fog" blurry but just a tad "off" compared to the Mk1. Again this is tied to the enclosure so this is transferred over to my hybrid. They also lack some of the depth that the Mk1 can pull off so the stage is flatter.

They are a little bit easier to drive but also present their own challenges since the top end can be a bit OTT on some recordings, similar to the He90.

I'll see if I have the parts and let you know.

Happy birthday!!

Have either of you looked inside the housings to see of the wires are too close together? I even fed mine some 700v+ of bias and they didn't complain. Was that aimed at me...? I'm going to make an adapter for use at CJ (people have to hear a normal bias Sigma off the BHSE ) so I can check if I have enough parts for two of them....

I'm sorry for your loss Ken and I'll raise a glass in his honor.

Does anybody want to sacrifice a Koss amp? The front panel has to be taken off to get inside the unit but it would be great to see the bias supply.
