Depends on how hot they get.

Horizontally mounted fins hinder proper natural convection so it's a bad idea for a Carbon.

I assume one of the design problems is the chip hasn't been made in like 20 years and his stock was running low. Any posts on SBAF should be taken with a massive grain of salt, but the DAC looks interesting. Will go through his diyaudio posts to find out more, thanks.

I haven't heard the HD800S but the HD800 sounds totally different from the HD650, to the point that if you like one you probably won't like the other. That treble spike is killer.
Sennheiser has subtly changed some of its parts over time, which they officially claim don't make a change in sound but really cause bigger changes than any aging. The pads flatten over time, which also changes the sound a lot, so they need to be replaced every 5 years or so (depending on usage).

The SR-007A usually goes for double that amount, which makes me doubt the validity of the seller but if it seems trustworthy then you should pounce on that! Stax headphones are electrostatic, so they are like Quad ESLs in headphone form, but without the transformer so you have to use a dedicated electrostatic amp. The entry level system is called the SRS-3100, which consists of the SR-L300 headphones with the SRM-252S amp. However, if you can really get the SR-007A for £695 then that would be the way to go, then get the cheapest standalone Stax amp you can find (another couple hundred quid).

Sadly, no amp or DAC will make a John Grado sound good so the best course of action is to buy better headphones. I think an entry level Stax setup is about $700 USD on this side of the pond so that is well within your budget, but I'm not sure how much they cost in the UK. Replacing all the pads on your HD650 will spruce it back up, and replacements aren't prohibitively expensive. Hope you enjoy whatever you end up deciding on!

RIP NBA, Hoodie Me7o all up in here

Uh... no. Given a sample size of 2 (Elear vs Utopia), the Elear has a mid treble suckout and the Utopia has a horrid upper mid/lower treble peak.

Happy birthday! How can you have any pudding if you don't eat your meat?

Obvious thing to do is check if the 20k resistor is shorting to something, particularly ground or something that is near ground. Why does it look like your input cap is about 5 meters long?

The Ether Flows are pretty crappy so that turned me off from having any interest in MrSpeakers stuff.

You own dynamic headphones??
And where are the sound impressions.
Also, what is the distance between input tubes on that amp?

and then

^ yup, and the resistors for the current sources still should be changed to 300 ohms from 250 given the 2V LEDs which run at ~1.9 in circuit. Everywhere in the circuit you see a current source like this, replace with 300 ohms:
Really it's more for the diamond buffer boards than anything else as IIRC I measured about 52 C on the PCB (also using 2V LEDs and 300 ohm resistors) and this was after I added heatsinks

seems like a badly done write-up of what Spritzer has stated about the Carbon for the past two years or so, blended with the usual Katz-magic: a touch of EQ ... wonder if Katz is aware of what ever is being written in his corner ...
There's definitely some touching going on, and apparently for both heads

Begs the question: How does he know what incestuous liquid sounds like?
Sadly, the article is littered with as much fake news as all the previous ones I read, and I only skimmed through like half of each. Where are all the real reviewers?
"thanks to the large circumaural Stax diaphragms."
"why manufacture an even brighter headphone when the 007 model already sounds too bright?"
"My measurements confirmed that unlike my older, custom AMB amplifier, the Pure Bipolar saturates much like tubes, it gently goes into clipping. In fact, it has such a high output capability that I would have to add an additional attenuator in my measurement setup in order to measure its limits."'
There's so much wrong with everything in this and everything else that I wonder how many times his mom dropped him on his head as a baby. Maybe she just had her way with him.

Opamp caps are 0603 package and use 300 ohm resistors for 2V LEDs (actual in circuit voltage will be more like 1.9). You need to at least somewhat match the LEDs before soldering them in so buy some extras
Edit: Y5V caps aren't good, if you are bothering with .1% resistors then get X8R/NP0 or at least X7R
