Could you explain more? Thanks!
The mainline does everything the Crack does and does it better. Tighter bass, maybe a bit deeper bass, but given the music I listened to not too sure about that part. The main thing was the incredibly natural attack and decay of instruments and a total lack of anything even remotely resembling noise or distortion. I really liked the Crack, now I know what all the excitement is about, but the mainline is on the next level for sure. Not to mention that the mainline can be used on a wide variety of phones, where the Crack is designed for high impedance only. I will say that the Crack is a lot of bang for the buck, as the Mainline is more than twice as much money. But if money is no huge deal then the choice is pretty obvious to me. I will be getting the Crack myself. I need to see what the wait time is, I know they were way back ordered just before Christmas.
I feel that I am now officially drinking the Kool Aid.
I have an ALO Audio MKlllB+ (after my MKll died ALO offered me a discount off their new HP portable amp).
I'm using the HD650 as my office HP.
The balanced mini out on the MKlll B+ was just too tempting not to try, since I can replace the cable myself on the HD650, for simplicity I bought the Green Line balanced cable from ALO and am blown away at the difference.
The audio clarity is kicked up a notch and the tone is smoother and silkier
Sound stage is wider, and as much as I love the HD650, the balanced cable seems to take the audio to a new level.
You can spend a lot more and a bit less on cable upgrades, but until now I remained completely unconvinced that changing out the HP cable would make any difference at all.
Even unbalanced the MKlllB+ is a nice match with the HD650.
I tell people this maybe the ultimate pairing for HD650, including the Crack. They don't believe me.
dxanex : this exquisite piece of art is undoubtably a masterpiece
IMO, the Lyr pairs better with the HD650 than the Pan Am, but the Crack is a different story.
Has anyone compare the Crack to the S.E.X. or Smack with the HD650?
Curious if the magic is limited to the OTL design.
I use transformer coupled SEP with my 600s and enjoy it as much as any pairing including the Crack.
