If the power is halving with half the load I would assume the amp is current limited at both loads. Just like you would expect halving of power with doubling of load impedance when an amp is voltage limited. With just this basic info, personally i wouldn't make sweeping conclusions.

I mean it is? It's just ohm's law.

All amps will decrease output power with decreasing impedance at some point. They are not made of infinite current after all. Of course the important thing is to look at the power output at the impedance of the headphone at hand. At 32ohm the V281 already has about double the power compared an...

Never heard it. I didn't mean to imply it's bad or insufficient. To me personally it seems perfectly fine with a Diana.

Or one that is specifically recommend and sold by abyss for Diana headphones https://eu.abyss-headphones.com/collections/electronics/products/broadway-by-eleven-xi-audio-fully-balanced-battery-headphone-amplifier "Excellent with ABYSS Diana headphone models." But only has like half the power...

Bump

Sennheiser HD800 with low Serial number 2293, Has some minor paint chips around the "L", the earpads are in good condition but the headband is quite worn and flat. The cable is frayed and fragile above the split but does still work without cutting out or anything. All this can also be seen on...

All Jude's measurements indicate a leaky front volume, would you recommend regarding his measurements as not objective and experiments as well? If some headphones handle a lack of seal better or easier to get a seal with it's just better in that regard. Measurements showing that does not mean...

You realize you're looking at two significantly different Measurement systems here?

Their Measurements do align pretty well. As I explain/show here https://www.reddit.com/r/headphones/comments/kxw8qe/_/ Considering reports from users i don't believe the worse seal situation is unrealistic, in turn i would say it's definitely useful to have Measurements with that kinda...

Amir's Measurements seem fine, of course would have been nice if he had posted/done more Measurements to fully characterize the behavior with regards to seal and positioning but the FR he posted doesn't seem like an unrealistic result. It's more that his Measurements appear to be incomplete...

I bet it's S rank

.

Hmm ye good point about waiting a bit, I'll do that for now, thanks.

Do you want isolation/is sound leakage a problem?

Did they say what they changed?

Has anyone compared the hd660S to a hd580 yet?

Does anyone know how large/deep the earpad openings are?

Just got my hd800 and I'm really enjoying jt, the 6k stuff doesn't bother me, would it still be worth doing the SDR mod?

That's the thing the PS4 controller uses Bluetooth afaik maybe my TV sends out an IR signal that my nfb28 picks up.

Thanks for the information, looking forward to the more detailed info.

Sometimes when i turn on my ps4/tv with the ps4 controller my nfb28 rapidly changes volume (sometimes up sometimes down) does anyone else have this issue or know what causes it.

Got my X6 for some time now, i think it's a great unit for the price. Powers all my headphones fine (hd580/eikon/hd800). I wish it had a gain switch though instead of having to open it up and change the jumpers. I'm also not a fan of the stepped knob, i would much rather have a "smooth" knob...

Just started posting on headfi after lurking for some time now, so hi everyone.

How about leakage, also similar levels as e.g. the th900?
