Okay, I'm starting to build a picture of what the new amp needs: Parasound, Sugden, Krell, Lavardin and NAD I've no experience of any of these brands other than older NADs, such as the 352, 370 which, although powerful, lacked openness and transparency. They weren't to my taste.
Leema Pulse. Sounds great with PMCs, Monitor Audio Silvers and Golds, Totems (Arros I've demoed), Harbeths; and someone I recommended the Pulse to years ago ran it with Dynaudio Exite (IIRC)
Tucana. Great with PMCs, Monitor Audio RS6s (someone from another forum ran his Tucana with Monitor Audio PL100), Totems. Include Harbeth and no doubt Dynaudio
Arcam SA30: Older Arcs were great with PMCs, Monitor Audio Silver or Gold, Totems; I think @hifinutt mentioned a few days ago he heard the A85 with Harbeth P3 and was impressed.
There's a pattern slowly emerging which is good and bad. It's good because I know what I like and don't, but bad because I need to be wafted from the comfort zone into another sonic dimension. Most important, though, whatever amp I go for needs to be flexible with sources and speakers.
This is why it takes me years (sometimes) to make a serious upgrade. I tend to dot all the Is and cross the Ts more than once. I know it may seems like I'm faffing, but every system I've had has been great and lasted me years.
