Too true! I tend to go on and on about hd800's, but 650's with the mainline really are sublime! Congrats on getting your new baby up and running.

Interesting.. so the Bifrost 4490 is worthy of the Mainline? Good stuff!

Dude 4490 is the real deal!

@dubiousmike, did you ever hear a difference while playing with the output impedance switch for the HD650/800?

@Pyruvate sorry for the much delayed reply on this! It is easiest to hear the difference in the bass, particularly with hd800's, although the effect is somewhat subtle. With impedance switched to low, deep bass is tighter and more detailed. Switch it to high and it gets a little more rounded off, but mid-bass gets slightly fuller.
