You really need a 1000V cap there since the voltage doubler easily reaches 700V...

Happy birthday old chap!!!

Ahh but the SRA-14S can be modified to take a balanced input. You'd have to rewire it completely and do some light mods to the PCB but the amplifier unit is basically a SRM-1 Mk2 which is fully balanced. Kevin sent me your patent a while back, very cool stuff. Btw. Here is the amp I was referring too, fully balanced and about the size of the old double CD cases...

It would be pretty cool to take the digital output from an iphone and feed it into a balanced dac and then into my balanced SRM-Xh...

I did something similar with the ESX. I needed a simple C- supply so four 9V batteries off the B- for a -460V supply...

Yup and it didn't fail me now. Who needs sleep anyway... I need to do some cleanup and trim a faction of a millimeter off the XLR loopout socket on the right plus drill the mounting holes for those but it was indeed a very tight fit. Also, yeah those are silver WBT's, might as well use them for something...

That is a very nice way to do it. I'm struggling to fit 4 XLR connectors, a 4PDT switch and 4 RCA's to the back panel in the small space between the umbilical sockets. About 1mm of space to spare and then there is that little voice saying "better not fuck this up"...

Right now I'm just not sleeping so I can solder in all the transistors on the amp. Well that and add XLR loopouts and RCA inputs/outputs.

How's your Danish? It was shown on the TV here but I've seen it floating around with English subs...

It´s alive!!!! I had a minor scare when I forgot to tighten one of the 485VAC wires (so the PSU made no sense at all) but it was quickly fixed. No noises and no smoke and the same goes for the + side as well. Now I just need to finalize the wiring and turn my attention to the amp chassis...

Good to know. I'm rearranging the wires now so back with some news shortly

It appears I have good news on the T2 front. Today is my first day off in a month and a half so I'm running at approximately 50% which is way more than is the norm. The first thing I did was to go over the PSU and everything was as it should be, all resistors matched the schematic and everything was properly soldered. So that wasn't the issue I checked the transformers and lo and behold, I didn't get any resistance readings on the 485 and 285 windings... Turns out SumR fucked up the data sheet so violet*/gray were listed for the 485VAC winding but it is supposed to be gray/blue. Ditto for the 285VAC windings, they listed blue*/green but it really is violet/green. Here are some pics of the other transformer under test but the resistance on the offending transformer is the same: Needless to say I'm not happy but I'm more angry at myself for trusting the datasheet... Now I just have to fix the leads and hook everything up for testing.

Yup...

Wise words my friend. My set will be from the first batch so Stax will have one angry viking on their hands if it isn't up to snuff...

The SR-Lambda is something truly special. It goes up there with the SR-1 and SR-3 as some of my all time favorite headphones...

The stock T2 was set to "oven mode" so it is entirely possible. They were almost crazy enough to run the stock amp at full power too...

The Lambdas (any of them really) are very good but they have always been more about generating a speaker like soundstage rather than absolute transparency. There is also some mild bass boom (though the new ones are much better here) while the SR-X is pretty much at a Grado level for soundstage but don't sound like poo (bar the HP-1000 though)... The KGSSHV is still in prototype phase but you can get the board files to have some made. The amp does work just fine and it is a screaming bargain given how advanced it is. First you don't like the SR-202 (probably the only one) and now the 4070? You need moar booze...

Those of us outside of the EU are a bit more problematic (Iceland, Norway and Switzerland for western Europe) as these countries all have massive import tariffs.

I do hate it when that happens. I was having some random issues with the first Egmont clone I built and it was naturally due to unsoldered joints. I had looped and clamped the wires (all done P-P) but didn't realize the error until I had stripped the amp for a complete rebuild. Here I was thinking the cheap Pfhier pots were acting up...

The Stax monitor headphones do take ruthlessly revealing to the n-th degree. The SR-X Mk3 Pro is very rare but the normal bias version is in great supply and with some simple mods you can get a bit more bass out of them. Properly seal the baffle and install new earpads will do the trick. For amps, I'm sure you know which end of a soldering iron to hold so why not build a KGSSHV? It's cheaper than the 323 and far outstrips it in performance.

Great idea for a thread since I need the T2 thread to rant about my PSU... The dedication to Dr. Hayashi was the least we could do to show our admiration for all the work he's done. Same goes for his father as without his groundbreaking work we would still be using inferior dynamics...

I've never liked a single ML speaker besides the original CLS but these "new" ones just appear to be the same crap, rehashed once more.

I'm with Dusty here, I started out with speakers but they never could give me the precision I craved. They are fine for background listening or the TV but give me headphones for music...

The pre-order price is nice but I'd expect another 10% on top of it in fees etc. I already have a set ordered so no group buy for me unless I can wear Stuart down and force him to get a set as well.
