Pass Labs XA 60.5 to drive Dynaduio C4

frankly, the modwright pre w/ outboard PS is excellent, should be a nice match. but if you have any ?s re: if the 60wpc is enough, get the 100wpc unit. ---i'lll cover this in a review i have coming on PFO in a week on the 60.5s. but short answer, there's so little distortion on the signal its easy to crank the volume, resulting in needing more headroom.

i do like to listen loud, but not that loud, and not that big a room.

you'll regret spending the money one time. you'll regret owning an underpowered amp the entire time.

I was able to ask personally with Dan Wright during the recent HIFI show here in Manila that the Modwright KWA 150 amp is 150 watts in Class AB and 20-30 watts in pure Class A mode.

Does this mean that the Pass Labs XA60.5 with 60 watts of pure Class A is 2 times the power of Modwright KWA 150 and can drive better my Dynaudio C4 ?

I also have C4s driven by Halo JC1s in a large room and current/power is never lacking.

I believe rhyno used to have the Halos also, as well as knowing the late great Bob Crump personally. Maybe he could comment on how the Halos contrast with the XA.5s.

I've listened to XA and XA.5s extensively but not on my C4s. My pre is the Pass XP20 and the XA.5s are a tempting upgrade but how much class A power is enough for the C4s I'm not sure.
