you guys should try it with some nice vinyl rig with nice cartridge and pre, you might be shocked what it is capable of :D even with some budget amp like emo x-mini, bass is out of this world, no ear piercing, ultra saturated mids and endless depth, everything just has some 'balls' and impact but that's vinyl ...
you know what ? even realtek alc on my motherboard gave me really interesting results ;]
once you get proper synergy with he-4 there is no other HP
I had many amps to drive it and every one gave me completely different sonic signature so you all should check out at least a few HP amps like Lyr, EF-5, audio-gd and at least one speaker amp driving he-4 directly from the taps to know what kind of beast is he-4 on something really powerful to feel the differences and choose the best combo
I am not hypeing it ;] this is just truly amazing HP once you find best dac and amp for your preferences, definately it has many different faces
In my opinion comparing he-4 to lcd-2 is super silly in every aspect although on some recording it can be really 'hot' but try some quality recordings - pure heaven, it just shows how bad or great your recording is, actually in time I got used to it so now I absolutely don't care anymore if it is 'hot' on some recordings, there are too many more important aspects
Unfortunately it is not in production anymore, you can grab last pieces now which are still on the stock in some shops
