I have been running a double amp combo since I think Craigster wrote about it a while back. I had been running it like this -
Source (iPhone 4 or 5) out via Fiio LOD into my E-11 on high gain, then out of that into the ZO, set on high gain (critical point) and on highest RED contour (highest bass output), and from there into the phones (in my case usually Q-40's. The E-11 is the volume control.
Now however, I just got a Schiit Magni and even though it is a great amp it needs the extra bass only a basshead can understand so THAT takes the place of the E-11. It sounds even better than the E-11, as it should.
What I found the double amping adds is better overall depth of sound, bass at low volume levels (almost like a loudness switch has been set), and obviously max bass at all volumes.
The purists have criticized me/us for this, but really, it's about individual preference and what works for YOU. I could care less what they say. I love the sound.
Ok I'll definitely try it then Thanks for the advice (and nice Schiit you got there, you must have a so deep rumble).
Gopanthersgo I need to wait a bit before doing anymore buying, but thank you for the info, I keep you in mind
Talking about warm phones, does wood brings that much difference with headphones? In a hollow body / acoustic I can understand, but I've more imagined that these would compare to, well, Stratocaster?
What kind of wood is the best then? Heavy, light, dense, fine? "Wet", "dry"?
