That reminds my locking RCA connector experience last year. I mean, before knowing the rotation needed to the barrels in order to loosen/tighten them.

That bottom chart is really nice, @ProfFalkin. If we awarded brownie points, you’d get some for posting that.

You will have to let us know how you fare with the 2020 Hibby R6. It seems like a it might be a great Dap looking at the spec’s.

Unfortunately, I already canceled the order. It looks like daps struggle with the bluetooth media controllers I want to use. (At least my dx160 does).
I am trying to find out which Bluetooth protocol those devices need so I can be sure it works. I am not very confident because the dx160 is BT 5 and seems to have many of the common BT features. But it wouldn’t maintain the BT connection.
Also, the only place I can get the r6 has a 20% restocking fee. As a rule, I won’t do that.

Nope, I think the really high end B&W at bestbuy driven by Classe $8000+ Amp. Sounded good.
I was just trying to get at the shrill it causes. Makes you squirm that I don’t experience with the headphones I’m using now. I’m guessing that elevated treble is what makes you experience that.
I got a chance to use my meridian prime dac with the HE6SE last night and Nirvana wasn’t working with it. A little too sharp, so I see now that the AKM and Burr Brown are the only ones that pose no issue.
Not sure what you mean by shrill, in the case of higher end B&W speakers. The diamond tweeters have good extension - cymbals have a lot of air, but they don’t seem shrill to me. When I mentioned the 802, that is their 2nd from the top, list price about $21,500. The 800’s are big, go for $30K a pair, I’ve never heard the Nautilus They look way cool, but $60K is a bit steep.

Hacksaw, a bit tangential but I was wondering how you find the Ananda’s as a compliment to your P9? I have the P9 and am enamoured with them, but was eyeing the Ananda’s as another pair. Your feedback would be much appreciated

I’m going to search through this thread again but I wanted to throw this out there. Looking for thoughts on similar sound to the Hifiman Arya, I like the warmer sound of the Arya but the ear cups putting pressure below the ears tends to get my goat. I started this adventure with the MMX 300 with Dekoni pads and from what I remember, it was comfortable with good bass, that was my entry into this world of tossing money out the window like a mad hatter. The single cable was probably my only pet peeve with Beyerdynamic headphones. Along that adventure, I’ve tried the Sundara, Ananda but the Arya was a better sound and usually comfortable for around an hour, then I need to put them down and come back in a bit. I’ve tried the Focal Clear and Radiance. The Clear was a little bright for me and narrow ear cups, my next pet peeve. I think that is the list I’ve tried so far besides IEM’s and I think I’m staying away from IEM’s and sticking to desktop. I’m looking for warm sound, good bass response but natural, not overwhelming, comfortable that I can wear for a couple hour sitting, I don’t marathon for the day but an hour is a little shy. It has to play nice with Bifrost 2 and Jotunheim which soon will be Mjolnir, so I’ll see what the hybrid world is like. I might order some ZMF but that’s a three month journal that I’d have to fire and forget for now. Oh, budget, hmm… around 800 would be great but 1500 is okay.

He6se. From adorama when on sale for 700. Then add a90 or flux labs (or a speaker amp to power)
It doesn’t have the soundstage of the arya (basically nothing does?), but man, if you like the hifiman sound signature, the he6se is brilliant when powered sufficiently. It’s “meatier” than the arya.
Now, I am an IEM guy, but that is the one I would have kept.
My 2 cents.

I’m not talking about the high end units, more on the cheap and neglected sets 
I don’t know, I guess shrill is bright.
I got mine for 699, it was 1100 off back Friday.
@Dynamic @cpp @Roikyou
Yea, I think they do need sufficient power, I think the A90 would work but I went with the flux labs FA-10 cause that is a monster at 10.5 wpc @ 50 ohms
My suggestions are coming from what I have researched not sure how much of a role it plays or accuracy. First, I believe this applies to the HE6 and may also apply to the HE6SE, they are the same driver I guess. Tests show from what I read they actually have a sensitivity of 77dB, so it’s even more power hungry than what HiFiman says. This was from measurements on a website definitely can’t validate.
Second, a few people have suggested at least 7wpc.
Third, I guess I do not know, that having really high gain is beneficial for the sound. The one I was reading or watched said you want at least 25dB gain and also a dac that had gain settings is beneficial.
I use it with the JNOG and high gain everything and it sounds amazing.
It’s really detailed and ultra clean sound, I don’t know if it’s different with lower powered amps. Also that’s how I feel and that’s only my second pair of headphones I’ve owned so I can only compare to one other headphone.
It’s a pretty hefty investment about 1700 on my setup
Mine died or I would probably still have them.
I was testing them on the a90 and a 100 watt speaker amp (with speaker cables). I didn’t get to hear them for long (before they died) but I liked what I heard on that. The a90 trailed by a bit.
FA was on the try list, but I couldn’t get one for weeks or more due to covid. I am not convinced it would beat the speaker amp.
I liked them more than the arya by quite a bit. However, I have been told that the arya scales just as well on a speaker amp. (Didn’t get to try this)
The thing I didn’t like about the he6se is there was always this nagging feeling of “what if I gave it even more power?”

FYI: the speaker amp would have been 16 watts per channel available. (Unless my math sucks, which it might)
Crazy good sound. Might buy it again one day.
I think that’s possible true, but depending on the gain as mentioned.
Second I think thd goes down with higher ohms, maybe wrong with that but depends what amp you were using and also its specs.
For 850 you can get the FA-10 pro and it’s not more power but it’s cleaner. So it would probably beat out the receiver.
Second the XLR in option on the FA-10 would probably have a small benefit, which the receiver won’t have probably.
But I’m not here to debate about it as I have no expertise, I got a Marantz 7013 and I didn’t want to use that and it’s 125wpc 2 channels driven at 8 ohms

Explain how power is cleaner?
I ask because the yamaha a-s801 seems to measure pretty well. Not as well as an a90, but it still beat that in the real world. (Measurements for it are on audioholics)
For reference it’s 100 watts into 8 ohms, which, again is 16 watts into 50 ohms. (Unless I messed up the math).
I used it’s built in dac. Still felt it was better than the d90/a90 stack.
This experience was one that taught me not to worry too much about measurements. Literally the top measuring stack was being beaten by a receiver not designed to do the intended job. Go figure.
Try your marantz with the right cable. You may be surprised. You may want to get the speaker adapter if you can find it. I read over 100 wpc can be problematic without it. (Hence buying what I did)
First off, I’m not exactly sure how to calculate numbers like these. Though I’m pretty sure you can’t just do multiples of 8 to figure it out. As in, 8 goes into 50 = 6 times, therefore 100 divided by 6 =16.666 watts @ 48 ohms or roughly 16 watts @ 50 ohms. I may be wrong but I don’t believe it’s as straightforward as that. Maybe that’s not even how you came by your number ?
This is the output stats for my V280 amp from Violectric.
max. output level: 1800 mW (600 Ohm) | 5300 mW (100 Ohm) | 3100 mW (50 Ohm) | 2600 mW (32 Ohm) | 1500 mW (16 Ohm)
As you can see things aren’t even multiples. Not only aren’t they even but it has more power @ 100 ohms than @ 50… a lot more ??? Also,the difference between 600 ohms and 16 ohms is minimal. Again ???
Why ??? I have no idea, lol. But I’m sure someone much more knowledgeable than me can explain it.
In any case, I’d like to know how this works…have a feeling it’s complicated

I used ohm’s law. And while I believe it’s true that power production does not need to be linear (for example tube amps are nuts), but your generic transformer based digital decent quality amp should be relatively accurate.
I haven’t done electrical engineering in 25 years. And I sucked at the math side of it then. So, take nothing I have said as anything other than a raving lunatic on the internet.
But, I used an ohm’s law calculator to work it out. I can’t say I used it correctly. But the idea is you work out the voltage based on 100 watts into 8 ohms and then take that and work out the wattage into 50 ohms.
Anyway, someone with way more practical knowledge than me should respond sometime.
