Truly what the SR-009's need, 8dB down at 20khz will take care of that nasty treble harshness and any HF performance altogether...

Wow thanks for the info as that puts this into a whole other light. So this is basically an Egmont or what Schiit deemed too bad an amp for 1k$... Here is the datasheet for the tube: http://www.nj7p.info/Tubes/PDFs/Frank/113-Soviet/6S3PE.pdf So we have only four triodes per side so it has to be this: About as simple as you can get and to charge people 5kUKP for this is just robbery. Funny enough, I made my own version of what I thought the amp was in the same form factor. Just sent the PCB's off to be made yesterday so I'll have something built soon... Only 39mm tall with a bone stock SRX input based on the 6N2P (though any compatible tube will plug in there) and 6N6Pi output with a simple 10M90 CCS. Only two coupling caps but with this novel idea of feedback...

True HC style then we'd be talking about an Accuphase E-600...

Welcome to the glorious world of high voltage.

It's funny with Tidal, they always recommend JayZ... for some reason... I thought the whole reason to pay for this shit was not to get ads for things one could not care less about?

There is certainly a lot of diodes on the center board but yeah, those heatsinks are tiny. They pretty much have to be 6N6pi's as nothing else would fit.

Well 50 years old but yeah... I kinda want to make a clone of this but better done and sell if for a lot less.

I agree, no HV regulation there and I found another pic taken at the same time: A few things spring to mind, see the red and black wires coming off the input board? Has to be the input wiring for the amplifier channels so they must just be on those small side boards. Also, they used the same twisted wire for the output wiring so the left channel has a bit more capacitance to drive. Pure engineering excellence here... I dug through the Russian tubes out there and the outputs sure look like 6N6pi and the inputs pretty much have to be 6N2pi which is the noval version of the 6SL7. Also the small PCB with seemingly few parts sure points to the SRX. This company also doesn't do SMD so that isn't an option to hide parts.

Now that this amp has been released and we finally have an internal pic, it is time for a dedicated thread. Here is some info about the launch event: http://hifilounge.tumblr.com/post/162193518708/trilogy-h1-energiser-for-stax-earspeakers-launch So 5000UKP... and nothing else which is relevant at all. The usual HF retards claiming this was the second coming and all that BS but here are the internals...enjoy: Not the best quality but good enough to know what is going on. In before Jim and yup...this looks a lot like an SRX. Some Russian dual triodes for the input and those look a lot like 6N6pi's to me. Two plate resistors as well. So over all, a pretty horrible way to spend 5000UKP...

Sorry for your loss Kerry

I went to the thrift store and there was nothing cool there until I saw this on a bottom shelf... They were asking 20$ with stickers that they were unsure if it worked so perfect for me. This is a PSU for Mackie mixing desks with a super long umbilical cable which I have removed. Heavy fucker too... at least 10kg. Healthy output current so the idea came into my head to use it as a bench supply should it work. After some cleaning it looked ok with no bad caps or any visible damage. Just look at that monster of a transformer. So I turned it on and well it worked so this was next: No current limiting here but hey, this one was cheap so who cares. Also I can test large class A amps with this beast.

Clearly superior to the T2...

They know about us and do care to some degree but are mostly annoyed by our comments...

Very good day...

Nope, that was the 007's and the SR-Omega. The SR-009 is the overpriced hype product...

Never seen that happen. Was it one of those cheapo hot air systems?

I don't doubt that will be the case. Just see the old SR-207 replaced with the L300 at a higher cost...

Eneloops are cheap...

With Stax, the price anywhere but in Japan will fluctuate for natural currency reasons so Stax prices never change. The SR-Omega was 180kYen in 1993 and only the 007Mk2 was increased to 192KYen in 2007. Hello zero inflation... As for the whole "flagship" business, it is just silly. I fully understand the whole issue of making something better can turn out to be really expensive but this stuff just isn't better.

There are a lot of misconceptions about batteries in audio so yeah, they have noise, power delivery issues etc. All of them really as the chemistry factor is so often overlooked in favor of the "free power" BS. Don't get me started on supercaps either...

Yup, very close to the 717 from memory, nothing like a stock 727.

So I've spent some time with the T8000 and my impressions haven't really changed. I've gone through a large portion of my collection with it and I sure as shit wouldn't use it with the modern Stax stuff. With 009's this is simply ear rape at any volume above a whisper. L700's as well though they are just generally sucky over all with any amp. The L300's just sound a bit brighter than usual and a bit dull which they normally do. With the 007 collection it's again a bit dull, lifeless and bright. Sounds have this annoying sheen to them which really shouldn't be there with the supremely neutral 007's. I also dug out the SR-Omega with the new leather earpads and same shit. Compared to even the cheap KGSSHV that is in development, it just lacks life. The soundstage isn't expansive enough and things are just cobbled together. The midrange lacks the presence it should have and the bass is just flat. There isn't enough texture and depth to it. I tried pretty much every Lambda ever made, SR-X Mk3 Pro, Sigma Pro and a pile of others but it's always the same. This amp is just lacking, no way around it. I would be annoyed with it if it cost 3k$ but for 6K$ I'm furious. Lastly, this thing sound awful cold. I normally just let my gear run 24/7 but with anything tube based I turn it off and I first though it was broken when I heard it cold.

Yes and no. There are solid dust covers on both sides of the drivers ever since the SR-Omega in 1993 (only on the front before that) so the drivers should be sealed but...the plastic is thin and tears easily so stuff can get in. Also something could be in there from when they were assembled as even though they have a clean room, shit happens. Phones such as the old HE Audio stuff, King Sound, Sennheiser HE60 and HE90 all have porous dust covers so crap will get in there over time.

I'm sure there are 4 coupling caps but this angle makes it hard to make out. Look at the rear 6SN7 and you see just a tiny bit of the other MKP10 cap behind it. I'm also sure they are using normal 6SN7's unless the current Russian ones are all A/B types?

The SRX uses 12 triodes so that's what they ended up with (or something like it) but this is the SRX: Quite an elegant circuit and the cross coupled stuff is something many modern engineers struggle with. This is what Schiit were doing: So, 6SL7 is just the highest mu (gain) octal dual triode there is so used for the front end to provide gain. The circuit above uses ECC83's which are more suitable for this role but 6SL7 would work. Then you have a single cap between the stages and the rest is all DC coupled. Probably the same as the Triology amp but supposed to sell for 1k$ and not 6k$.... Now see how this compares. 6SL7's on the right feeding through a cap (red Wima) to the 6SN7's on the left. Probably three 20K plate resistors or something like that and the servo on the cathode to control the offset. Then you have the PSU on the extreme left, two HV supplies with series 350V caps to handle surges (which 500V caps would have handled just fine) and the regulators on the small heatsinks. Small PSU beneath it to run the opamp, relays and stuff like that. Bias supply could be the small transistor and diodes to half wave rectify and regulate. Heaters probably AC as they float at -400VDC.
