i'm currently rocking some Infinity RS4s, love them for all kinds of music, but especially metal.

I have an L50 and it is quite flat and transparent, showing off your headphones abilities but also the charateristics of your source. I prefer a slightly warm and weighty sound, which is why I use a DAC with a Burr Brown chip.

I would not say that the HD6XX is an upgrade by any stretch.

I personally vastly prefer the sundara over the HD6XX, they sound almost boxy to me due to the lacking treble and sub bass.

AKG are now owned by Samsung, which could have gone either way. sometimes when a compnay is perchased by a larger one the increaased fund are great for product development. Unfortunately not the case here.

thanks for the advice everyone, sorry for the late reply my notifications were turned off for some reason. In a twist I have changed my plan, as I have bought a new DAC and Headphone amp secondhand since posting this thread, which just came up cheap at the same time. I've bought a Schiit Modi 3...

Has anyone used the FiiO K11 with either of these headphones? I'm looking to upgrade from a FiiO Hip-Dac, and I need a 4.4mm output aswell as unbalanced. This seems to be a perfect option for me, I'm just wondering if anyone can confirm that this is a good pairing with the Elegia and Sundara...

Tidal -> FiiO E10K -> Sennheiser IE80

if you look into second hand then Senheiser IE80 are insane for bass, and sound excellent otherise too.

I would not recommend the Red for a Basshead, not sure about the others.

I guess 0.05V is a negligable difference.

arguably it could drive them fine with the single ended output, depending on how loud you listen. I find the Sundaras to sound excellent out of my AK jr, which has slightly less power (1.95 vs 2.0 V RMS)
