Continuation of R2R DAC Discussion From Stax Thread
spritzer replied to Sechtdamon's topic in Home Source Components
I'll fly in and out via NYC and I should have one night by myself so I'm up for some shenanigans... -

I'll be visiting Kevin at the end of March so I'll try them out and see if I them better than the Wiha stuff. -

They are US only and nothing like that here. -
Excellent!!

20V of drift is nothing to worry about.

Continuation of R2R DAC Discussion From Stax Thread
spritzer replied to Sechtdamon's topic in Home Source Components
I normally use the Wiha 36050 stippers but they do wear out after a while with the 24# teflon stuff. The Wiha 24672 is supposed to be better but I need the bloody PTFE cartridge for it... -
The EP-5 is indeed the massive hybrid with a horrid coiled cable and 5 wires inside it. I was going to take the easy route and not bother to ohm them out and figure out what they were doing with all of them. The PEP-79's were excellent. I have the PEP-71's here with the massive wood grain adapter and the plan is to someday do a bunch of youtube videos about these. Plus the Stanton Isophase (very, very odd those), PWB's and a whole lot of weirdness I've been collecting.

I'll throw something together eventually as I need a balanced DAC for my test setup. What is the USB input of choice these days? Still XMOS what ever? -
One thing cropped into my head, didn't you once have a Suprex EP-5, Justin? I bought one but it lacks the TRS plug and the multitude of wires has made me go all "mehh" so I didn't reterminate.

Can I blame you too for the 150$ Wiha wire stripper I bought which really doesn't like PTFE wires? I need a new cartridge for those... It will sure be fun to compare it to the MSB. They sent me message asking for my email address so they can send me the drivers so that is a good sign. The Soekris modules are also sitting here but I have no idea what to do with them. -
Anybody remember how angry he got at CJ'10 when Justin lent Tyll some of his headphones to test?

Yeah I bought one... blame Kevin as he's such a bad influence on me. It's shipped but I have no idea when it will arrive... -
The real problem with these is that they have to be messed with. My ECR600 had a nasty channel imbalance which never went away and that cable... yeah... it has to go as it is dangerous.
-
I saw a set of two with an energizer going for 1300$... that is beyond insane.

I might do a version of this circuit with SS CCS just to make it a lot less complicated. -
Have you seen the asking prices of ET1000 sets these days? People are nuts...

Find a cheap set of SR-507's...

Computers also have so many internal SMPS that feeding it all from a linear one is just silly. -
Megatron Electrostatic Headphone Amplifier
spritzer replied to kevin gilmore's topic in Do It Yourself
It's excellent, nothing short of that for an all tube design. Gives the BHSE a run for its money... -
Yup and many have issues with the epoxy coating so they could short out. I've lost count of how many I had throw out due to that. That's why I stick with the CMF60
-
I had one of those once so I have a pretty good idea what the ECR800 is like on the inside. Well that and the horrible cable...yuck!!! Turns to goo... I've seen 400$ for the earpads at some time if you can get somebody to sell you a set.
-
I was tempted by the SRA-8S but it is identical to the SRA-7S aside from some humpots so I passed. Not going through that restoration hell again... Nice ECR-800 but pretty useless without the adapter.

Now, now stop this!!! You are worse than the cultural revolution!!! I so wished I was there but about 5 weeks until I'll be in NYC...

Megatron Electrostatic Headphone Amplifier
spritzer replied to kevin gilmore's topic in Do It Yourself
I finally finished this one today after about... 4 years or so... Let's just say that I hate anything with umbilical cables... Besides the madness of using 4 mains transformers and the super short filament winding's for the CCS tubes this was easy enough. Running at +/-400V off a BHSE power supply with the dropper resistor and zeners to feed the front end. Only main difference is the 12VDC supply used to heat the front end tubes so the board was cut up pretty bad. Next one will use the Megatron V2 pcb's in about 3 years or so... -
Could very well be. Hard to know exactly what is going on though...
