Did you ever try to sell the Aleph on Audiogon? There appears to be some market for the DIY Pass stuff. It's much cheaper the ebay too.

SAVING UP!!!!!! You Scot's and your crazy ideas...

It's been confirmed that the pic is free to be posted so here you go:

Ok, but wasn't it behind closed doors? Hey, I'm a Nordic God so I can do what I please. If that's dressing up in drag then thats my business...

I took the picture down since I'm not sure if I could share it in the first place and I can't remember who sent it to me. I have a lot of pictures that can't be shared so better to err on side of caution...

Here is a picture of the insides of the amp. I can't for the life of me remeber where I got it so if it steps on any toes, will the mods please remove it or I can just remove it from the 'shack. If the other stuff in this price range even approached to be half as well designed and executed as this then there could actually be some competition to speak of. I don't think that he uses Tango iron as they usually have a cutout at the bottom with terminals and not lead wires but it could simply be hidden from view by the PCB. The CCS is clearly off board. Btw. I approve of the Metcal soldering iron...

Do you want me to loan you Mj

Hey!! It hasn't even recuperated from the last crash... :'(

Don't forget that you can take the same design priciples and apply them to a 'stat amp too. All triodes with either direct or transformer coupling... yummy.

Congrats!! I plan to spend this Friday night stuffing four Blue Hawaii PCB's with parts. Mmmm PRP and Holco resistors...

The SR-007 pads should fit the SR-5...

Well KK did dig deep on some info on Peter's Balls which were a great read about where Quad could have gone and also there is some great info on how the ESL's came of age. I did enjoy it tremendously... 'nuff said.

Happy birthday!!

Looks great but where are the internal pics...?

DIY is certainly the way to go but you could pickup an old Sugden or something like that. You could also just put some resistors inline with the headphones from the NAD to lower the volume.

Will do. If this design doesn't pan out then we'll just have to start on a new one.

The ESP950 is a stunning headphone and you may want to look into changing the damping at a later stage but if your happy, then your happy.

The order I placed was for enough parts for two amps plus quite a bit of random ESP stuff/BH parts and the total was 250$+shipping. I bought a 280-0-280v/55mA R-core off ebay for 40$ and some 2SJ74's at 10$. The case I have (Galaxy or I find something nice and gut it) and quite a few of the parts needed (standoffs, RCA sockets, volume pot, IEC inlet, fuse holder, vector boards, stax sockets etc.) but they aren't expensive. This amp will be SE only though as I don't have a balanced source so that means I have more choice with pots. Odds are I'll go with a Noble here as usual. Yeah, that's never going to happen. The 717 is about 7-900$ used and a screaming deal at that so a 300$ amp will not beat it but it will be fun trying. That being said the target headphone is the Lambda range and a simple, affordable DIY amp that most can build is clearly a good thing for the community. That is will probably outperform the RSA A-10 is just a bonus...

I just placed an order for all the parts needed to build the Poor Man stat amp. Now we'll see if it is possible to build an amp for less then 300$...

No, not really. Sure both are forward but the 4070 is far more reserved and without all the sonic artifacts that the Jade has. The bass on the 4070 lacks bloom but it very detailed and tuneful which can't be said about the Jade. The upper midrange is more open on the Jade but that's just due to the closed nature of the 4070.

I'll see if I can make some time for that. I need to have my stash of Stax brochures at hand so I can't do it "while working" I'm sure our helpful Wikiphonia admin could add it to the side. The Stax cable is: + B - - B +

Just for your info I got the newest HFN this morning and there is a review of the Sony. I just glanced through it but they quite liked it and the measured performance is very good indeed.

There are + and - stators and they are identical or we would be seeing a lot of distortion. Like Dusty said it is all about absolute phase and I can hear the difference easily. I even made a cheater plug that reverses the phase on Stax headphone so that I can compare... Is that thing still flagged for lack of references? I really have to make good on my promise and write a few articles for Dmitriy's site...

Just as a reference for anybody else who might read this thread, with Stax cables the pinout is the following: Of the three wires which go to each ear, the wire with the line printed on it is +, the wire in the middle is the bias and the last one is -.
