For me, not even if you switch tab and come back to it, even without exiting and re-entering entirely. From testing with a low shelf filter very high up (at 8kHz), while it shows the shelf on the graph, it's not actually setting it at all. It's only ever a peak filter. This is again, part of the...

@FiiO shelf filter on the new firmware is not working for me. It at first seems like it has worked, and appears in the graph OK. But when I swap to another EQ or tab and go back (so it reloads them from the device) the shelf filters turn into peak filters. Any tips would be appreciated. As a...

Hifiman add phase distortion to their R2R, don't they, that would potentially give a 3D "effect". You could add this to a delta sigma DAC as well, but they tend to prioritise accuracy, just the sound without added colouration.

Fiio K7 is 6.35/4.4, no XLR. SMSL C200, M500 Mk3. Also plenty of stuff that has XLR but 4.4 as well. And more and more headphones come with 4.4 not XLR, like the Sennheiser HD800S changed to a 4.4 stock cable. Moondrop Venus stock 4.4. Sony's TOTL MDR-Z1R is 4.4 as well. I do think it's more the...

Thank you for this suggestion. I am using the Android Fiio Control app. I tried this on a secondary phone and it worked and I was able to set the EQ on the secondary phone. When I go back to my main phone, the EQ I set on the secondary phone is there, and now if I make any changes on my primary...

Mine have stopped taking any custom EQ whatsoever, one day they lost the custom EQ I had in there and changing anything custom no longer works. Doesn't matter if it's PEQ or just the straight GEQ, doesn't work at all any more. Now if I make changes they show on the graph but no change to sound...

I don't think it does, on a specific IEM (the XSL X-One) it has the same impulse response and phase behaviour as that IEM does with a regular analog 2 pin cable. The Quarks DSP does look a bit weird: XSL X-One analog cable: XSL X-One Free DSP: This is the change I'm making with the...

The FreeDSP is absolutely transparent, it's a good DAC. Up to 384/32, while the Quarks DSP only does 48/16. Not that that matters in and of itself but it's an indication it's a different DAC. Quarks DSP has a noise floor, this has none that I can hear. Moondrop posted AP measurements which were...

It's best with IEMs, as it's actually quite low power for a dongle. And despite Questyle's claims of "current mode amplification" it is particularly short of current and particularly weak into low impedances. It's absolutely fine for any IEM and many over ears, you don't need power for IEMs. But...

You need to order directly from KZ: https://www.kztws.com/products/kz-castor

No, impedance adapters do the opposite, they present a harder to drive load and reduce the volume. Whether they affect frequency response at all depends on the impedance curve of the headphones. Many IEMs have a totally flat impedance curve and in that case an impedance adapter will only make...

So I got the Red and the 10Ω impedance adapter, and it is between as expected, still lower than I'd prefer 4-8kHz but I think tonally this is better. If I could only find a 10Ω balanced impedance adapter that would be perfect.

This is interesting, unlike most planars which have a totally flat impedance curve, these are actually affected by impedance, and higher impedance will actually drop the treble. This also makes them even harder to drive of course, but if you have a powerful source should still be OK. I'm at...

@seanwee there is a difference with foam, I did also measure and listen to them with foam and it does dull them a little bit but it's far less than the difference between the high treble and low treble variant, that's what I mean. I get the same difference as you with foam vs spring tips, the...

I definitely saw a reply from him on Facebook, I think to Fahryst who posted these measurements in his Bad Guy Good Audio Reviews Group, that that unit was wrong and "not a PR2" and to contact Tyvan and that it would be sorted out, that he guaranteed it...

I think you should be good if you have the black rectangular mesh on the driver. All the reports I have heard of excess treble so far, they have been missing the mesh. This is Pregcog's PR1 Pro and my PR1 Pro, which is virtually identical to his, just to indicate it's not my coupler: And my...

This is the new vs the old KZ x HBB PR2. They sent the original HBB tuning around to all the reviewers, got the reviews, then radically changed the tuning because apparently it was too much effort to apply the black damping material consistently. The new one has WAY too much high treble, it's...

@emdeevee I think they should have replaced the cable without you sending it back, they have replaced cables for me and didn't require me to send it back. Sucks with the Z1R but I'm not sure this can be entirely blamed on the cable, Z1Rs are known to do exactly this and they do it with the...

That tool won't work for the Sony MMCX, they are recessed. That tool needs to get into the joint under the MMCX to push it up, and it can't do that with a Z1R, the joint is recessed down inside the IEM. It is actually possible to use most regular MMCX with the Z1R but you can't use that tool to...

I have this on the Aria, it's very well made, good connectors, doesn't kink like the stock Aria cable. Only negative is it's a very bulky cable, I wanted to use it with the Oxygen but it wouldn't fit into the Oxygen stock case.

Pin size is diameter of the pins, 0.78mm. 0.78mm would be very short if it was the length! Like Carpet says, that looks like it might be a TFZ/NX7 connector. You can use a regular 2 pin with them but you're better off using the proper connector which has a plastic shroud that goes over that...

It should fit. This isn't the same cable but it is XINHS, same ends, and these are the non-recessed type. The non-recessed still have a little bit, enough for the Simgot EA500 which is only very slightly recessed, it's not like the Moondrop Aria/Starfield/Kato which have a substantial recess...

That 9kHz peak is the insertion resonance, it depends how far you push it in. Most standardize it at 8kHz but you can measure it at 7kHz with a shallow insertion or 9kHz with a deeper insertion. What you actually get in your own ear depends on how deep you push them in, most people, it's lower...

Rescue, you are continually evading the question. What does "in the player itself" mean, does this mean you are doing EQ not on the FW5 at all, but in a "player"? It's specifically PEQ, not GEQ, and I think it specifically seems to be when you enter multiple bands with frequencies that are...
