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.

Discussion on the design of the T2 & other circuitry
spritzer replied to kevin gilmore's topic in Do It Yourself
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...

Holy Crap! The New Stax Omega Looks fierce! (Stax SR-009)
spritzer replied to Jon L's topic in Headphones
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. -
That sounds like a plan. My transformers are the same SumR spec as most of the other T2's built to KG's spec. No megaohm tester I'm afraid but I'll wire up a bridge and a cap tomorrow. Edit: I'm with KG though, it's only the cap and the parts around it (the copper conducting the heat?) that get hot so this is bloody strange. If this was some stupid mistake on my end I'll be so pissed...
-
Turns out the cap wasn't mislabeled (unless the connectors were also mislabeled i.e. not likely) and after installing a new bridge as well the problem is still there. KG thinks the transformer is fubar and thus the AC is too high but I did test it before connecting anything and it was on spec. I'll test it again just to be sure but an internal short in the board or an incorrectly labeled resistor are all possibilities at this point. I'll probably fire up the +260V supply to see how it behaves since it uses most of the same parts. I can also swap the windings and see if it makes any difference.

Holy Crap! The New Stax Omega Looks fierce! (Stax SR-009)

Guess I was bang on the money WRT to the MSRP. I have already had a set reserved for me so I better get cracking on the T2. As for the MSRP, there is virtually no inflation in Japan so prices remain pretty much static for years. The SR-Omega was 180KYen back in 1993 and the same can be said about the SR-007. It wasn't until the A was released that the price increased a bit. Now street prices are a different matter and since the SR-009 is likely to be in short supply for a while at least so prices should be close to the MSRP for a while at least. -
If I have a spare bridge then I'll replace it as well but first I'll just replace the cap and see what happens. The rest of the PSU was just fine with no excessive heat generated. Now I really need some sleep before tackling the high voltage...
-
Thanks guys. Kevin took some time to think about it and he thinks it may just be a fubar cap or that it is incorrectly labeled. Makes sense since the PSU works except for the noises and excessive heat. It's a good thing I bought a box full of those caps so plenty of spares.
-
I've been turning on the T2 PSU in steps these last few days and it almost blew up in my face. The -260V supply went into meltdown mode and the 680uf/450V cap was burning hot after running for about a minute. Now comes the utter joy of figuring what went wrong...
-
What you haven't opened it up yet? Btw. I spy some of my handiwork sitting next to it...
-
Yeah, I've tried the HRT and it isn't bad but not terribly good either. Fine for that role but with access to far better DAC's I'll take a USB->SPDIF over it any day. I guess I've settled on getting an M2Tech Evo and building a new PSU for it. Now I just need to find someone who'll ship it here or call in some favors from my US friends.

Happy Birthday!!!

Any version of the Gilmore Dynalo (G-lite would fit the bill) or a M3.
-
The HD600 is far from a bad headphone and since you are a detail freak I would suggest something DC coupled and with enough power to breath some life into the phones.

STAX SRM323 schematic - balanced input
spritzer replied to purrin's topic in Headphone Amplification
Not necessarily, the male Rean mini-xlr's should fit in the current holes: You still need to add a switch if you want to use both types of inputs though... Edit: The stock pot is 50K -
Holy Crap! The New Stax Omega Looks fierce! (Stax SR-009)
spritzer replied to Jon L's topic in Headphones
LONG LIVE ENGRISH!!! Prices do appear to be all over the map but it's hard to pin it down without the price in Yen. Looks to be around 400K Yen once you factor in what the Mk2's cost in the EU. That would be the SR-007 Mk2. The SR-007 was the 7th TOTL round model Stax made, the SR-Omega the 6th etc. That's at least my understanding of how the system works... -

Pfft... real men custom order 4-gang pots just for the hell of it... -

Odds of finding a split section pot like the one Stax uses are zero so you have to get a new knob as well or do some drastic mods to the current one. -
I blink and my torrents are here. Hell, the ancient boot drive in my server is the real bottleneck, not the FiOS connection.

Jude thinks RSA makes quality gear so no...
