wow, you take off 2 hours to watch a movie and then all of this. if that class B output section could actually deliver 1 amp or more that is required for just about every single planar or ribbon then maybe it might actually perform correctly. but the opamp cannot possibly supply enough current to drive the output stage. all the feedback in the world won't help. and for real world loads R2 actually makes it worse. multiple feedback loops and it looks just like the squarewave of the nfca module. more like a stair step. something the AP cannot possibly measure. hint: look at the quad current dumper. class B output section. performs well within its power limit. all this to reduce the current capabilities of the power supply. all this to reduce the heat generated because the heatsinks are way to small. yes its a piece of unreliable garbage.

Thank you for making my day less boring and answering my question. I will label you as a troll and a psychopath.

From your welcome message when you joined all of an hour ago "Don't mistake our familiarity with each other as familiarity with you" "Spend some time reading before you start to post. Get familiar with what is going on, and who the various people are. Don't just jump right into the fray." "This is your only warning"

Lol. Seriously, why are you still in a place filled with people you contempt? Your existance and behavior contradict with each other. Just shoo away and let everyone be happy.

Well, High Rollers. You can’t debate an angry person, waste of time.

And the balanced switched attenuators, and many more. And Sprizer is the forum expert on headhones - particularly Stax electrostatics. Which is precisely why a newbie is encouraged to spend time reading around, finding out about who people are, and what they know and contribute before leaping in.

Marta's debut album is a collaboration with Tricky, so of course it's good. Moody as shit, too. I'm in.

Do you truly believe, all other things being equal that class B will sound better than class A? In the world of amplification for speakers class AB, B or even class D is tolerated because its more efficient than class A and at high output powers pure class A is often impractical, and prohibitively expensive. For headphone amplification efficiency is not an issue given the tiny output power required - which makes pure class A very practical. Because of this there are few reasons to design anything other than class A headphones amps (portable headphones amps excluded because efficiency and power consumption matter here). Kevin Gilmore has designed and helped us build many fantastic Stax amps, for example the blue hawaii (which several companies sell), and of course the T2. He is incredibly experienced and is generous enough to open source his designs AND support those who build them. I would strongly think again about criticising his competence.

Horrible story indeed. Glad the perp will at least face trial.

I see we have a member of the audio religion in our midst, how fun to see the scientologist poke their head out of their echo chamber. Arguing whether Class A is better than Class B is fucking retarded so let's not but the question of measurements is a fun one. Are you measuring something that actually matters or is it voltage swing in an electrostatic amp, meaningless stat that is measured in the one spot that makes it even more meaningless? If you go from 0.01 THD to 000.1 THD... how does that change the sound? Do we have hearing good enough to spot that or are we picking up something different? If something measures badly but sounds good, which is correct? If you claim something terrible sounds good... do you have enough experience to know it sounds bad? Just because you have ears, doesn't mean you know how to use them. Same goes with a scope or a test suite, just because you have it, doesn't mean you know what to look for. If you take a cult leader, hand him a device he doesn't understand because he's as thick as brick, he measures it incorrectly and claims "I don't understand why anybody think this is good"... was the device at fault or was the cult leader being retarded? If you smother everything in feedback, can you hear that? What if you remove all the feedback and make an unstable circuit, can you hear that? There are so many good questions out there...

"So I will ask again, because no one has dared to answer it: Can a design with objectively flawless data be dismissed as 'crap' based on an outdated topological label?" <-------you unilaterally decide that the topological label is outdated have you considered that I (I almost put we but I don't want to put words into others mouths) do not accept this premise. Unless you wish to be flexible in a debate and have a little bit of an open mind (and a good helping of respect) debate is meaningless. no design is "objectively flawless" this highlights your black and white thinking with zero nuance. Surely objective flawless would be 0% THD infinite frequency response etc. this is obviously impossible. So again I reject you impossible premises. "Who started this by calling a product they hadn't measured 'crap'" < ---I DID NOT "Who, after failing to debate, issued a threat: 'This is your only warning'? " <--- I DID NOT and you decided you won the debate. I don't believe you have but you obviously have a strong desire to win at any cost under your imposed rules and premises and if they are not fully accepted you think you win by default. "Who just used the term 'cheap plonk' in a passive-aggressive insult against other people's choices?" <----- I DID NOT I did not mention the word cheap. I said PLONK - plonk can be expensive I used to it refer to something that the drinking find of low quality - in other words I acknowledge the drinkers choices and they get to decide what they consider to be plonk. threats?? what threats? when have I threatened you? (perhaps I might be threatening your ego) "It was you lot" <- again your black and white attitude that all the people other than you in the debate are the same. lack of nuance. "play the innocent victim" <- how have i attempted to play the innocent victim? I entered the debate with a rough idea of the direction it was heading and I was proven correct. You language and insults have progressively increased (I assume because we are not insulting you back and that's what you deeply want inside to fight physiologically injure us and for you to win. You proudly proclaim you have already won, I think the others in this "debate" may not quite see it your way - and maybe that's the entire problem here. Can you accept that others can have valid views different from your own?). At every step I have tried to debate and you insult rather than debate, or perhaps insulting is your debating style? I cant speak for others but I am not made angry by your words just saddened. I also question if you have a place in this forum, but its not my place to decide and I have not reported you to the moderators (this is NOT a threat its a fact). "We're obviously happy as we are," <--- I did not say this but bare in mind this forum makes no money from membership and (in my opinion) is a fairly close nit community of (mostly) like minded individuals. There are debates and arguments from time to time but usually this is amongst people who have been here a while and at least got to know each other a bit and have some respect for each other and some tolerance. tolerance is something you seem to lack along with reflectivity. I can't decide if you are a troll, deeply troubled or a psychopath. Ether way I wish you well and hope one day you discover the grey between the extremes and learn that you don't have to win every debate because sometimes the debate/journey is more important. regards James P.S. ultimately you might also want to ask your self why did you join this forum?

I like lost causes.

Let's wait until the US wakes up, eh? You don't have any information where on the planet you are.

Heh, I got you. https://www.discogs.com/release/7077621-Clipse-Lord-Willin See some for around 67, but have found used for around 50-55 without looking too hard. It's totally worth that, IMO.

Kinda interesting to compare size of the full frame Sony RX1R III f/2 and the $200 cheaper medium format Fuji GFX100 RF f/4.

Thanks. I guess nobody likes to receive fake parts. But if it’s a low-current, 1200V or better grade IGBT, its characteristics can come very close to the SiCFET we use in threshold voltage, transconductance and even input/output capacitance. It might actually work, at least in the GRHV. I’d be interested to try it out. Well, we should probably stop talking about SicFET or IGBTin this thread, as they are irrelevant to T2.

Ooof! A bit rich for my blood lol. My copy is below: https://www.discogs.com/release/11978254-Clipse-Lord-Willin (which I thought was quite fancy, apparently not enough haha)

Latest additions. GT4RS and BAC Mono I do fit the Mono, just can’t breath

Dear lord. Today's news is insane, and leaves me with more questions than answers. Sunny was a tough woman. Not superhuman, but definitely world wise and not easily intimidated. She grew up in a harsh environment and knew how to fend for and defend herself. There's some missing piece of this story we still don't know. Is this kid a physical giant? Did she know him? I suspect she did. Did he manage to sneak up on her? This would be an insane story in any location, but in a quiet town of ~2000, it boggles the mind.

(Edited for pronouns) RIP to poet (and more) Andrea Gibson. I hadn't really listened to them, only HEARD OF them. But with their death, I watched and listened. And....they were STUNNING! I watch several of their talks/poems and often times I cry, for their pain & beauty. Examples:
