From tiny Silverline's to slightly bigger PSB's

I have heard the Minuets and other PSB speakers, but not the Syncrony line. FWIW, I always find PSB speakers too forward in the upper-mids/lower treble. Also, I would not describe them as "smooth." Of course, the Syncrony might be better, and Jolida makes a nice smooth-sounding amp, so YMMV. What don't you like about the Minuet that you think the PSBs will improve?

My take is exactly in line with Bondmanp's. I have not heard the Synchrony line, but I've never been too crazy about the PSBs I have heard. In contrast, I think the Minuet is a remarkable little speaker.

All of that is to suggest that you listen before you buy. And the Minuets are so small, you can just drag them along for an A/B.

the synchrony line is as balanced as anything i've heaed in the last ten years.

PSBs are incredibly linear at all their price points, with a nice, natural room-filling dispersion. In general PSB and Paradigm sound better than their asking prices would indicate, as they use Canada's National Research Foundation's sophisticated psychoacoustics studies and R&D facilities, dramatically reducing the R&D costs in the selling price.

"What don't you like about the Minuet that you think the PSBs will improve?"

The Minuet is an over achiever, but it can't fill my large listening room. This is not the fault of the Minuet, it is user error in not matching a speaker to listening space. I'm guilty of this. For desktop, small to medium room, near field listening - the Minuet is an absolute joy to behold, a reference/recording monitor selling for a song. My search for a used speaker system for my large listening room that matches well with my Jolida JD 302 continues on..
