spritzer

I sent them an offer for one so we'll see. Expensive shipping given it's next door and less than 1kg...

The 2SA1486 is perfect for this role and so is the STN9360. If you have a KSA1156 that measures well above 600V then it will work too. Just remember the pinout difference.

Apparently pigs can fly....

Not a chance in hell that those are real. Bdent has the real deal but they are not cheap. On the new boards these will be swapped out for STN9360's.

I wouldn't use the KGSSHV psu as it just doesn't like that load. No mods possible with that PSU board which is why we are slowly working on a new one.

Try switching to the 3GS/4... it is just comically small in comparison.

The teflon male plug is certainly real even though they were not cheap. The first prototype is on my HE90: Neutrik XLR male pins are perfect for this role. Not sure if Kevin has any more as only a few of these were made.

Indeed, the CCS isn't active as the LED is missing. Also the soldering on the feedback selector is suspect and with the local resistors also in place that could short and cause problems.

That reminds me too much Single Power so don't do that... No caps on these but then again the PSU is 10mm from the amp boards.

Something is blown or shorted. Also the LV supply is kinda high, the 7x15 regulators should never be that much out of spec.

The Russian Blue Hawaii (FluxLab) uses a lot of adhesive which tends to get not so adhesive when it warms up. Top tip, glue and a 200W space heater doesn't mix. Funny enough that BH and it's sister amp run pretty cool for the breed. Much cooler than the BHSE for instance.

Adhesive would be very much in the vein of Single Power so I use screws.

Nope, busy building these... Finishing up the last of my old BH stuff. The black one is running in now.

Indeed... perhaps it's time to post some pics of the last flagship?

The ST is something special.

Looking at the picks on Moon Audio.... this is one fugly set of headphones. Seriously, did Ray design this pile of fail?

Board is always correct, the BOM probably isn't. I moved to smaller caps in the LV supply to save space when I did the KGSSHVk boards. A 500V 3900pf will work especially with the 270V zener in place.

There is the Momentum Bluetooth which is suppose would be huge for them and not us. We did discover a huge flaw with the pre production (or early production) wireless sets as they appear to be volume capped and it's not nearly loud enough. 10K for anything Hifiman is madness. I guess that's why they were so touchy on HF when people called it a fugly headphone. Also the amp is in a chassis that costs way less than 100$ for both boxes in China....

Be careful with those screws as... well Sennheiser uses the cheapest crap they can find so they strip easily.

I did confirm today that the HD800 is indeed not discontinued and it's just the slew of wireless units that they are coming out with. I could have tried them but couldn't be arsed...

Sennheiser are still selling the HD600 which they should have discontinued years ago so the HD800 going away isn't bloody likely. Still I can check on Monday from the belly of the beast. Also Changstar as source is just precious. Might as well believe that the new HE1000 is the best headphone ever made as they are saying on HF....

I really like that one. I have something very special on the backburner for the "ultimate" KGST and I need to move it ahead in the row of priorities. Today the first GES Mk2 is taking shape with the new PCB's. Roughly half the size of the Woo Mk1 unit and it's fully balanced, with a better PSU and far less distortion...

That's what Stax do

It says HD800 - Black, which were discontinued by Sennheiser or rather never made it to serial manufacture. They always planned on having a silver and a black one before launch.

You could also have left out about half of the holes.
