Yes, I'm hoping for exactly that!
Actually, it's about my last shot at finding a solid state amp that will justify keeping the HD800, without spending a lot of money.
Keeping this as brief as possible...
I bought the HD800 without having any particular amp in mind, but I knew that it has a reputation of being finicky.
Even after burn-in, I didn't like the HD800 with anything I own, nor anything I've borrowed - all solid state - except for finding it "tolerable" with my TBI Audio MG3 > TBI resistor network that imposes 15.8 dB attenuation to kill hiss from excessive gain in the MG3. For me, the problem has been not enough bass and too much treble, but I love the detail, imaging and sound stage of the HD800. It's like a girl with a beautiful face and crooked teeth. I want to take my HD800 to the orthodontist!
So, several people suggested I try the Schiit Vali hybrid amp > HD800 and as of this writing, the Vali is the best HD800 solution I've heard for handling any type of recording (without spending a ton of money on a proper tube amp and going OCD with rolling tubes) - but, I've come to realize that the Vali is intrinsically noisy and puts a bit of a sheen on everything, even though I really like the FR it yields with the HD800, and even the detail it preserves.
Then I got the Beresford Bushmaster MkII DAC/amp (which is known for being warm and having great bass), where I liked it not quite as much, so I tried feeding the Bushmaster MkII analog out to the TBI MG3 > resistor network > HD800, which was getting real close to being ideal, until I got some HD650 and realized just how little bass I was hearing in the HD800, even still, and... how much dynamics and even resolution were being lost with the attenuated TBI MG3.
Going back to using the Bushmaster MkII DAC + amp directly into the HD800, I've resorted to creating an HD800-specific playlist - with recordings that don't demand much bass performance, nor have anything shrill happening in the treble. These recordings, like solo guitar, or guitar + vocal, or pretty much anything acoustic - when played through the Bushmaster MkII - directly into the HD800 really show off both the Bushmaster and the HD800, with no ill effects.
My last hope, short of buying an Eddy Current or Cavalli tube amp (and I'm not even interested in something more affordable like the Woo WA6SE, as I've heard that they color the sound to "fix" the HD800 while also degrading some of the resolution), is to make my iBasso PB2 as warm as possible - it's the only amp I can tweak in this way. The goal is to "fix" what's wrong with the HD800, without degrading what's right.
I've found that I can pretty much emulate the sound of the Bushmaster MkII's amp section by equipping the PB2 with OPA1612s in I/V and dummy buffers, so that gives me more power than the Bushmaster MkII's amp section outputs, but I want treble warmth and more bottom-end energy, with as little impact as possible to the micro-details and separation that are rendered so nicely by the Bushmaster MkII > HD800.
Just from reading, I have a hunch that I will get closer to what I'm looking for, if not Audio Nirvanna, with this chain:
Resonessence Concero (as USB-to-SPDIF converter) > Bushmaster MkII analog out (bypassing its amp) > iBasso PB2 equipped with LME49990 in I/V and Muses 02 as buffers > balanced out to HD800.
Of course, I'll probably be rolling some other combinations, as well, including Muses 02 in I/V with dummy buffers and OPA1612 in I/V with Muses 02 as buffers...
I can't believe I'm about to start rolling opamps again after keeping a lid on the PB2 for so many months...
Which all begs the question... "What's your favorite rig for use with your HD800 (PB2 or otherwise)?"
