Ah, that's interesting, and makes sense in terms of what the various SRDs actually look like. I'd always trusted the Stax history page, but clearly it's not totally accurate.

Also, looking at the Stax history page, I see that the SRD-1 had variable bias! (If only we could do someting similar to get our ubiqitous SRD-7s to drive our Pro-bias Stax!)

Variable bias is relatively east to do, just look at the bias supply in the Gilmore amps.

My SRM-T1w has 2 Pro and 1 Normal bias outputs. One of the Pro outputs has a variable bias. I don't think that it can be adjusted down to normal bias levels but looking at the schematic could give some insight. I do not have the schematic. Interestingly the Stax manual says to use the variable bias control as a volume control to match levels of different phones.

You can only adjust it down to 500v. It's a simple variable voltage divider if I remember correctly much the same as is often used to drop the Pro bias down to 230v in amps.

I repeat - the carbon ICs have qualities which can be appreciated only with headphones. Try them.
I use Van den Hul "the Second" but there are another carbon ICs on the market.
Thanks brat-I'll give Van den Hul a try. I'm finding the sound on my system a little bright at the moment (although I'm told the brightness is not so pronounced after 200 hours use?) and I'm hoping the I/C's will give it a warmer sound?

Hopefully PriceJapan.com has reasonable customer service and can rectify this in short order. No response to my e-mails yet, however.
DHL delivered another box from PriceJapan.com this morning and this time there was an SR-007A inside! I can attest to their great customer service in rectifying this matter promptly.

First listen to the SR-007A is very promising! Very different from my SR-404 -- warm and extended with no obvious peakiness. Also a wonderful and solid 3-dimensional soundstage. Now, I need some time with them to let these phones and my ears break-in!

That was quick!
Guess its time for a short congratulations then. Hope you enjoy it.

I finally got my SRM-T1 yesterday and after listening to my O2 MK1s, got to say they are the best i've heard so far. Now I really want my BH SE

Hey Mafia

I came across this image in my web surfing.
1980s Japanese magazine cover.
WTF is up with the black eye?

Maybe one of those Sigma pins came loose?

Question for Stax gurus: according to the info I found on wiki and these boards, there are a handful of Stax amps that can drive both Normal and Pro 'phones.

I only own normals at the moment, but I anticipate moving on up (bias-wise) at some point in the future. I'd love an amp that won't run into obsolescence when I do.
Are any of these dual-voltage amps decent? If so, which should I look out for?

My SRM-T1W has both Normal and Pro outputs, though I don't have any Normal headphones.

It is decent. It drives the Airbow SR-SC1 and 4070 quite well, and the SR-Omega also does surprisingly good. However, I don't think it's a good match for the SR-007 or SR-007Mk2.

I doubt there's anything with a normal bias output that does justice to the Sr-007s.

Except, of course, the BHSE with a normal jack. I could get one, but I would have nothing left to listen to it through, nothing to plug into it, and no wall remaining to plug it into. Seems like a real "ground zero" approach to system building.
