I didn't think any of these existed as there was the ATR version for studio use which had a stepped attenuator and balanced inputs but in almost 20 years of searching...none have turned up. Then I came across this one last year in Japan in pretty rough shape with tape all over it. I naturally over payed as usual but then again, how often does one find something like this: So years ago I did this and nice to see Stax did the exact same mod as me. Remove the 100R resistor to ground on the other side of the fet and put two resistors off the board in its place. The amp also arrived with one channel dead, shorted transistors and almost open resistors in the front end. Now for the money shot... This is clearly stock from Stax as all the screws match what they used at the time but one odd thing is that the markings are actually engraved into the back and not simply silk screened. Can the volume of the two channels be adjusted separately? Not 100% sure but I think this is the first machine made by stax which has a 4-way VR, not even for srm-monitor which also has a balanced input

Also second photo shows four sections to the volume control, which is what you would expect for a balanced amp.
spritzer Posted June 1, 2019 Report Posted June 1, 2019 Yes, dual concentric volume control on this one and I'm pretty sure this was the first balanced Stax amp.
Mach3 Posted June 5, 2019 Report Posted June 5, 2019 You have so much rare stuff spritzer, I'm surprised you haven't setup a museum already. ? 1

SONY ES Posted July 10, 2019 Report Posted July 10, 2019 Hello everyone From what I understand Srm-T8000 Does not justify the investment I have 009 + 006TS The source is SA 11S1 MOD NIAM DAC +TP SUPLAY+ROTEL 975 AS TR SO NOT TO BAY THE STAX -T8000. AND WAY IS SO BAD????? THANK YOU 1
Hotrod28 Posted July 11, 2019 Report Posted July 11, 2019 Stax noob here. I have an nb Lambda and have been using a srd7. I recently purchased an srd5 to pair with the lambda because I removed the fiber glass on my lambda for fun. Anyway, when I compare the two transformers the srd5 specifically gives me a channel imbalance. Left side is high volume and right very weak volume. I know for a fact that it is the srd5... Any suggestions? 1

jvlgato Posted July 18, 2019 Report Posted July 18, 2019 Geez ... I haven't been around much lately, but I don't want to come back and see the kind of post that Sony ES put up! Sony, take a break and look around for a bit before posting. PLEASE!

So this is claimed to be an "improved Carbon" but the only improvement I can see is an added chance to burn your house down or give you a nasty shock. Seriously, this is apex level shit and how anybody would ship something like this out...is just beyond me. Also, gotta love "thinker" who consistently shows any possibility to do just that.... 3 1
Mach3 Posted August 7, 2019 Report Posted August 7, 2019 I saw that and I was like. WTF was that fan doing there??
kevin gilmore Posted August 7, 2019 Report Posted August 7, 2019 (edited) ok, this scares the shit out of me. hennyo level of quality here. Second pic, the power supply in the upper right is an ebay high voltage switcher that's $7 I know its $7 because I bought some for the up and coming stax mafia portable, and its actually a pretty decent supply but can handle only about 5 watts of output power. You can see two more under the fan. Fan is required because those things get hot especially when you try to push them over 8 watts. And according to people at diyaudio that use them for tube preamps, the main diodes blow up at 10 watts. No way is this a kgsshv-carbon in terms of power. Barely 10% if that. Also limited to about 400v A pair of switchers on either side of the pot drive the HV supplies. So Switchers driving switchers. Not the most quiet of things. And the rest of it, yikes power supply pics here Edited August 7, 2019 by kevin gilmore 2 1
Pars Posted August 7, 2019 Report Posted August 7, 2019 Man, that's some quality shit there Nice solder blob on the left side. Thinker: Excellent built. Cue up some Talking Heads - Burning Down The House... 5

Scgorg Posted August 7, 2019 Report Posted August 7, 2019 (edited) I knew this clusterfuck would have to make its way here at some point. Impressed at how fast it happened. I'm starting to think this thinker guy is either: 1. A shill, he has shown a serious lack of restraint for praising products over the moon in the past, including Perun products. Hmmm... 2. An unrelenting fanboy who can't conceive that someone he likes would make a sub-par product, let alone garbage. Rest assured I'll have to agree with Birgir that thinker is not much of a thinker, nor tinkerer Also, for those who want another gem from head-fi, some guy is selling a KSE1500 with a kingsound portable amp that he claims is substantially better (just lol). If this wasn't bad enough he has reterminated it to pro-bias plugs and the cable is a fucking braided cable in the style of typical IEMs. I lack words for how dumb this is. https://www.head-fi.org/threads/wtt-wts-d10-dac-km03-electrostatic-amp-kse1500-bundle-last-price-drop.908902/ Edited August 7, 2019 by Scgorg Added in more stupidity 1
kevin gilmore Posted August 7, 2019 Report Posted August 7, 2019 (edited) Ok, the stax mafia has spent quite a bit of time with the kse1500 first the headphones are 200v bias. The kingsound must have been modified to lower bias voltage otherwise these headphones will eventually pop. yes the kse1500/kse1200 is an extremely low power classAB amplifier with significant distortion. But great battery life. The kingsound is a chip amp driving transformers. Might actually sound better, but definitely not stax mafia approved. A really good battery powered portable electrostatic amp is harder than you might think. The stax d10 is another example that has issues. Edited August 7, 2019 by kevin gilmore 3 1
