600's have a lot more bass on my OTL amp (BHC). More bass by a lot than on my Ragnarok 1 driving XLR cables.

Yes, it's not news to anyone that it leans slightly warm, so of course warm amps can further slow their bass decay. By "low end" I meant <30hz. You can try to EQ their subs somewhat, but you quickly run out of headroom, because you can hit a massive %THD+noise brick wall, which is amp-independent. That's not to knock them. They're only $200, afterall. When the HD650 was released it was around $500, which is like $1000 today. HAHAHA. I could've bought a DT 880 + a nice desktop amp instead, but I was young, and bought into the Senn hype. Well, my $40 Moondrop SSR iem today sounds x10 more accurate than mid-price Senns, even with the much smaller soundstage.

I find where the 600/BHOC pair extends the bass is from 35-70 Hz (vs every SS amp I've paired them with) - and pretty linear for an amp with bass decay/THD.
For a long term dipole fan/owner that's most of the battle (a functional bass from 35-70 Hz). It's nice to have 20-35 Hz (it's almost an octave after all), but 98.5% of what I listen too has the music above 35 Hz. You can buttress the 600 with EQ to get to 50 Hz range - but as you say it flattens the dynamics. But its the 35-50 range that gives me a sense of foundational bass, and justifies the side trip to an OTL amp.

I take it that you've heard them all

But this aside, is there anything specific you don't like about our stuff? Or is it a rather general feeling?

KPH30I since you can get Etymotic ER2SE for 20 dollars more

Personally I think your amps and DACs all suck if I use it as a can

Agreed. They don't seem to be playing any music at all! What a waste of money!
