HD598 is too lush and soft for my taste.
HD-700 has that HD-800 magic without being gear picky. Try the new Daft Punk album on the HD700 and you will be wowed. Go back to any HD below it will be like stepping back in time to a darker past.
I find the HD-700 gear picky, although not as much as the HD-800
Did some testing with different amps and dacs. The following where used.
Amps:
Vioelectric V100
Leckerton UHA-6S.MKII (OPA209 OP AMP)
O2
DACs:
Meridian Explorer (Chipset: Texas Instruments PCM5102)
ODAC (Chipset: ESS Sabre ES9023)
iBasso D7 Sidewinder (Chipset: Wolfson WM8740)
O2 + ODAC:
Works OK. Somewhat sharp treble (imo), otherwise ok balance.
V100 + ODAC:
Same as with O2+ODAC, but as it is a more powerful amp there is more punch.
V100 + Meridian Explorer:
A little better than the O2/V100+ODAC combo as in less sharp treble.
Leckerton UHA-6S.MKII + Meridian Explorer:
Didn't like this combo, very sharp treble. Made the HD-700 seems very V-shaped in signature.
V100 + iBasso D7 Sidewinder
This is my favorite combo. The dac (Wolfson chipset) gives it a darker signature which tames the sharp treble and removes some of the coldness experienced with neutral dacs/amps. Of course the treble is still very forward but in a better way (imo), very detailed and smooth.
Conclusion:
I find the HD-700 perform its best out of a warmer dac and probably a warmer amp (imo). V100 is considered neutral perhaps just a slight hint of warmth. O2 / UHA-6S.MKII are very neutral and I didn't like them with the HD-700 in other words I have some problems with it's sound signature in its original form. The warmness of the Wolfson dac takes care of that problem for me. Haven't tried tubes but I'm sure those can also work well with the HD-700.
Those of you that like the HD-700 - what amps and dacs are you using with it?
