While we discussed EQs and such for these headphones, I'd like to get some recommendations for amp pairings.
At first I thought that due to the size & weight of these, I would use them in home only, and my home amp (Corda Concerto) works very nicely with these. I have yet to find a headphone that doesn't sound great with the Concerto btw!
But in the last couple of weeks I started to use it on the go / in the office much more, and I actually find it quite good on the go, especially after pad change which makes these highly isolated/ isolating.
However, my mobile amp I think is not adequate for these. I have the Vamp Verza, which I think has a much too high impedance output to drive these. The VV's output impedance is a very high 10 ohms, while the JVC's impedance is a very low 16 ohms. When plugged in to the VV, the JVCs sound a bit harsh, and seem to be much more fatiguing. I recently started to plug the JVC directly to my ipod (classic, latest version), and I think it actually sounds better straight out of the ipod than it was with the Vamp Verza.
Directly out of the ipod, with the ipod's EQ set on "rock" (classic V-shaped curve), the sound is pretty fantastic, and not really veiled at all. I feel that without the EQ setting on the ipod it sounds much more distant and veiled. In fact, the audible difference between the different EQ settings is really substantial with this headphone - other headphones seem to not change quite so dramatically between different EQ settings.
So, in short, can anyone recommend a good mobile amp or dac/amp that will work great with the JVCs? (preferrably ones that are compatible with apple devices). I had my eyes on the M8 for a while now, but it's a bit on the pricey side. Given the very low impedance of the headphones, I'm also wondering if amps made for IEMs would be the way to go.
