We've seen confirmation from independent teardowns as well as directly from HiFiMan that the drivers themselves are identical to the HE560 v1/v1.5, so if anything any differences would be down to the cups or the (removed) backplate. Honestly, until we see measurements directly comparing the...

Seems like the Lyr 2 is a popular pairing with the HE560, which is cool to see. I'm really enjoying my v3 paired with 1970s Czech Roznov tubes in the Lyr 2, which are known for their bass impact. Like the others above, I have EQ'd them to add a bit of low-end bass, a small bump up at 500hz, and...

Ah, I see what you're saying. It's just that I don't see any evidence on the measurements of the HE-560 being any worse than the Sundara or the HE-500 (as mentioned previously) when it comes to high-frequency peaks. I have not heard these side-by-side, myself, so unable to comment on subjective...

I don't recall seeing this characteristic of the HE-560 referred to as a "treble spike" (as in something that shows up on an FR graph) so much as I see people describing the HE-560 as a "bright" headphone at the upper end, which is a little different. If there was a harsh high-frequency peak on...

Well if you don't like your Emu Teaks, then possibly. But the HE-560 v2 is selling for $250 right now on Adorama and the Emus cost twice that through a Massdrop, so you could probably sell them outright for more than that. If you like the 400i, then I'd say it's a near certainty that you'll...

Check out a few pages back in this thread (page 1349 starting about half way down) where we discuss this. My recommendation would be a Topping NX4

That is too bad! Yeah, I'm hoping someone gets around to measuring the newer models eventually. Would be really interesting to compare.

Not that I'm aware of. But if they're going back anyway, why would it matter? I would think the most recent purchase would be the one to worry about. Regardless, if the yoke breaks I've heard from several people who contacted HiFiMan support and were sent a Sundara headband to replace it. FWIW...

If your pair has the wood veneer on the cups and the old headband, that would be the v1 or the v1.5. FYI. As for whether or not they sound the same: I've seen some people say that the bass doesn't hit as hard on the new ones, and I've seen others say they sound the same. HiFiMan confirmed that...

I'll just say that I really like the newer headband from the Sundara. It's one of the most comfortable and one of the best fitting of any of my cans.

You'll find the full answer to this by reading earlier in the thread, but the short answer is that they had some issues with materials quality leading to broken yokes (fixed on the v2 and newer) and ill-fitting headbands (fixed on the v3), these models are a little bit cheaper to manufacture...

For use with your mobile devices, I had the Topping NX4 recommended to me for these exact purposes (portable amp/DAC suitable for driving planar magnetics). The reviews are excellent.

As long as you plan ahead you're careful and rig up something to hold the grill away from the driver once it's free (perhaps paper clips through the grill holes or something), I think you'll be fine. But as far as dismantling the cups: I have not done this so I'm not sure if that would be wiser...

If you're going to remove/replace the grill cover, just be EXTREMELY careful when you do, because as soon as you remove the plastic retention ring, the internal magnets will try to - very strongly - pull the edge of the metal grill straight into the thin foil driver material and you could wind...

I'm really enjoying the sound of these on my Lyr 2, as well. I'm currently rolling 1970s Czech NOS Tesla Rožnov E88CC tubes in mine. I've also got the LISST tubes, but those haven't been as exciting. Which Mullards are you using along with the HE560?
