If you have a normal SRD-7 you can turn it into a Mk2 if you are handy with a soldering iron.

...and no I'm not selling either one of my Mk2's...

The real reason for posting was the voltage issue with my T1W. It was marked by Stax as a 100v only unit with no signs of an external switch. I was relived to see on the PCB that the primaries on the transformer were connected to something that looked a whole lot like the Stax voltage converter. Sneaky Stax had fitted it to the backside of the PCB as they did with the T1 so it wouldn't be clearly obvious. It is switchable to all of the voltages (100v,117v,220v,240v) so if you are buying a used Stax amp from that period and there is a black square with lots of wires going to it, odds are that is can handle all the voltages.

Hmm would you mind taking a picture of it? I think my SRM-T1W is outfitted the same way. However the voltage issue aside, goody-japan hasn't received my amp from the seller yet, and it has been over a week since I won that auction already *worried*

Here's an interesting amp on YJ: http://page18.auctions.yahoo.co.jp/jp/auction/w13509406 Not quite a bargain deal but it still looks interesting...

I'm sorry but I can't take a picture of it. The amp is crammed into the rack right now and my camera is on its way to Holland.

I've waited more then 10 days for a JP seller to send a package so I wouldn't be too worried. When two weeks pass then I'd start to be a little worried. You can send me a picture of the amp, when you get it, and we'll take it from there.

That is an interesting amp if only for it uses the Illusion stax plug. Combining a Stax and a dynamic stage in the same amp isn't all that hard, just install an output transformer where the Stax output is and you are set.

Ah, Birgir, here we go again! You make this sound so easy, but I still don't know how to actually go about this: I can solder but can't read the circuit diagrams that've been posted here! (This idea looked it was actually going to take off a few pages back on this thread, but, as so often before, it died a death... )

 

[Salt Peanuts]

So I tried to search/read through the thread, but I wasn't able to find the info (most likely missed it even though it was right in front of me).

For those of you who own 4070's, how long did it take for you to receive them after placing your order?

Also, what is the US price for 4070's? I'm just wondering how much of a difference there is between the US price and importing from Japan, and if the difference is worth the possible warranty fun.

I got it from www.pricejapan.com in less than a week - there must have been some stock at the time.

By the way.. I wonder if Hedamp has any KGBH SE left, now that I've placed an order as well!

I don't want to speak for Justin, but most amp makers are not big (in production) enough to keep stock of their amps.

I was referring to the fact that it's a 'special edition', limited to 10 only.

It was a comment not really related to your question, but rather directed at the other thread participants... Sorry for the confusion!

The MK2 is the pro bias - correct?

Can a normal SRD-7 be converted to pro bias by swapping out the transformers?

It isn't very hard but you have to know what you are doing. It is live AC voltage we are dealing with and you can kill or injure your self and/or start a fire. The circuit diaphragms are pretty simple but you have to observe polarity of some components but it's easy to build a bias supply on a perf board. Then you only use the board for support and connect the component leads directly.

I know there was one KGBH SE left last night according to Justin.

The transformers are pretty much the same but it's the bias supply you have to replace.

Hello, I am new on this forum I am reading for several weeks.
Having had for 20 years lots of headphones and amps, I wanted to try STAX.
To begin with, I bought a pair of LAMBDA PRO with a SRM1/MK2, and a SRD7/MK2. First combination : very good, clear, dynamic sound (after SENNHEISER HD650 + EQUINOX cable).
But second combination, with MODWRIGHT SWL 9.OSE preamp + CONRAD-JOHNSON MV60SE amp = NIRVANA !!!
I thought I was in the dark quietness of my music room, but in reality, I WAS in the Berlin Philharmonie in 1978 to hear Herbert Von KARAJAN conducting VERDI'S Don Carlos (not particularly well engineered !).
The voices of Mirella FRENI or Jose CARRERAS entered in my body an soul with their whole richness of tone. I had "chair de poule" as we say in FRANCE to describe this emotional mood.
So, I have a question for you, eminently STAX specialists.
A friend of mine goes to TOKYO in 2 weeks.
Do I ask him to go back with an OMEGA 2 to replace my LAMBDAS ?
Shall I enter in "OVER-NIRVANA" then ?

Welcome to the forum!

The Lambdas are very good but the Omegas are much better at everything. Their sound signature is very different as the Lambdas are a little bit forward and excessive bass bloom while the SR-007 is neutral and can be a little dark when mated with a sub par amp or if it is in a dark sounding system. They have the best bass of any headphone but it isn't overblown and always according to the recording.

The SR-007 isn't very expensive in Japan now and you could even find some used phones at an even better price. Be warned though that there is an updated version to be released soon, the SR-007 Mk2. We don't know exactly what the changes are but they should sound pretty much the same as Stax is mainly fixing some slight issues that have occurred over the originals 9 year life time.

I have almost every Lambda ever made and an upgrade to the SR-007 is a clear step forward so go for it!

Does anyone know where to source PRO (5-pin) headphone jacks? It seems that they used to be available a couple of years ago, but are no longer supplied by Stax. I know there are some substitutes out there but their quality is nowhere near as good (with the possible exception of those used in the Illusion transformers).

I suppose I could try the Australian dealer, but I am somewhat reluctant after they quoted me USD$150 for a SR-001 replacement cable.

 

[spritzer]

Stax stopped selling them when the demand skyrocketed due to all of the third party amps so now we are all stuck with the WPI stuff. You could try and ask the makers of the Illusion if they are willing to sell the jack and Woo Audio also has their own version.

I wouldn't use the WPI stuff on any of my amps so I have bought quite a few SRD-4 adapters and removed the jacks. It's expensive and it's very easy to make a mistake and break the jack. Another option would be to find a SRD-7 Pro and remove the jacks and fit WPI unit instead and sell it again. Everybody isn't as crazy as we are...

 

[luvdunhill]

I talked with the guy that make the Illusion at length. They are not willing to sell the connectors separately (or perhaps, but only with the amp)...
