Yeah if I ever win a billion dollars I'm going to do all the measurements that actually matter with all the high end gear and figure all this stupid stuff out once and for all. Why nobody measures the important metrics, I'll never know. It sure would be nice to be able to just look at a spec...

I use a pair of Parasound A21+ to drive the HE6 and Susvara. They're rated at 1100wpc and measure in the real world at about 2000wpc. Yes, they like powerful amps but there's a fact in the way and that is that you can not feed them all of that power. It's not an opinion. I would put the pair of...

The power has zero to to l do with it. Zero. Nothing. If you put 1mw @ 60ohm into the Susvara, it will play at 83db. I've driven them with 1500wpc and the HE6 with worse results than a $250 headphone amp. High power amps do hold together better, but you can't put even a 5 watts into them and...

@sajunky is that one with the battery a constant charge isolated battery? like does it charge while being used and still maintain full isolation without a separate power input?

If it's in warranty, the supercharger is covered but I had a Funk die on me out of warranty and they sent me a replacement board for free and I just slapped it in and it was fixed. I think they'd much rather just replace the supercharger than refund the amp and either way they're still not...

I'd talk to Burson. They're really really helpful. I've had a couple issues with some of their stuff in the past and they just handled it no questions asked.

@awesomenatorrad it's probably the power supply. Were you using the regular non supercharger power supply? I've never heard of a supercharger dying, but I've heard of dozens of the standard power supplies giving out.

make sure all the silent power modules are PERFECTLY straight up and down when putting the lid on and put it PERFECTLY straight down and they should squeeze in place with the little foam on the underside of the top cover. had it happen and about crap my pants but everything was fine.

Yeah, sounds like a Supercharger 3A. I don't know that is necessarily the problem, but I do think it's relevant to the issue.

So there's a sensor inside the amp that tells it not to turn on if the lid is off and people have had issues (me included the first time I swapped opamps) with the amp not wanting to turn on afterwards after removing the lid and putting it back on. I'd make sure the screws are nice and tight and...

This sounds like it might be the problem, but the way it's happening sounds like the failsafe for the top cover not being engaged. Have you opened the unit up and changed opamps?

Basically brand new Sennheiser HD490 Pro Plus package with everything included and the DearVR software code still unclaimed. They're super nice headphones, really comfy, well built. Can include a balanced custom cable for a little extra (the one in the picture) that also works as an...

A dedicated DDC/streamer that does upsampling internally like an Mscaler, but price it reasonably. Give it an app to change filters. The market could really use a hardware upsampler and it really shouldn't have to cost what the Mscaler costs to achieve the exact same results.

great buyer. fast payment. easy to deal with.

Yeah the differences were fairly minor, BUT there's quite a bit more power handling capabilities with the 2023. I really didn't notice it on anything but the HE6 line (4, 6, and se v2) but it is definitely a pretty decent leap with those and another thing I noticed that isn't really a big deal...

The Burson V6 opamps have reverse voltage protection built into them so if you install them backwards it doesn't hurt anything but I don't think that's common with most other opamps so putting them in backwards can damage the amp I believe.

Functionally perfect. Comes with remote, updated V6 Vivid opamps (lower noise, pretty much dead silent with sensitive IEMs vs stock V6 Vivids that had a bit of a hum) installed with a Supercharger 3A. The screen does have the common burn in that they all get but it's honestly really not all that...

The balanced XLR 4 pin on the 2023 is silver around it and the older ones are black.

I was noticing the exact same thing with my HE6se v2s lol. The staging always feels drastically more open and natural when the bass is super tight and well controlled on the HE6 and it was just so noticeable on that headphone for some reason. The micro detail was a huge leap in my experience...

Well for starters it says if you try to start it without the lid you can void your warranty but it presses the silent power modules into place to make a good connection (tons of power going through them, you don't want a bad connection) and it has some kind of auto shutoff that enables when you...

The lid has to be put back on.

It's probably the silent power modules. Make sure they're perfectly straight up and down and when you put the lid back on, go perfectly straight down and once you're down don't let up and the foam on the inside of the lid should press them down harder and they'll make connection. It scared the...

Lol little bit of light ribbing is still allowed in this world, right?

Oh stop being pedantic. It works flawlessly. I know its ugly an people can cry all they want about imperceivable losses from the extra connections but just try it and you wont care the second you hear it. Nobody is sitting and watching you listen to music judging you because of an extra adapter...

Specifically the 4.4 IEMatch is absolute perfection for IEMs. Literally zero noise whatsoever with any IEM. The 4.4 one has extra impedance to calm the noise down. Also for what it's worth, I've never in my life heard so much detail out of some of my IEMs. Just plugging them into the 2023...
