There was an old comparison in Stereophile of the 5B to the SCM19 V1; kind of came out in a tie. I have the SCM20 pro passives (virtually same as the SCM19 V1). I love them, and find the low end remarkable for a sealed enclosure. It’s accurate and very well defined, but also goes deep. I’d think the SCM19 V2 would take all the good things from the bass and mids and have even better treble. They’re also very easy to place in room. You have to go listen to speakers for yourself cause it’s going to be a question of taste.
I use the P1 but others have reported the AHB2 drives the SCM19s really well (think the thread is still on this page). ATC just came out with a new SIA2-100 integrated which should be cheaper than the P1. The power amp section of the SIA2-150 integrated (which sounds really great) is the same as the P1. I believe the SIA2-100 uses the same topology but just a lower rated transformer.
Actually the AHB2 seems to in fact cost a little more than the P1. It wasn't available when I got my stuff; I find the P1 pretty perfect for the SCM19s/20s. The P1s don't really have a sound as such.
