From tiny Silverline's to slightly bigger PSB's

If you are considering Johnnyb53's suggestion of a small floorstander, and since you like the Minuet's sound, the prelude would be the natural step up. Very small footprint, twice the mid/woofers, and a larger cabinet. IMHO, the Prelude offers more of what's good about the Minuet. In any case, you should focus on high-efficiancy speakers, whether monitors or floorstanders.

Johnnyb53:

"If you really like the sound of the Minuet you might be able to fix this with a powered sub to offload the LF duties, increase overall radiating area and open up the Minuet's dynamic range."

Johnnyb53: Already doing this with my old PSB Subsonic 5i (powered). My listening space is b-i-g. I mean big as in 34 x 15 with elevated sloping ceiling and right side open to other rooms. Problem is my other rooms are too small to move my system into - it's either the cavern or the closet for me here.

I have wanted to sell for a year and a half and leave this redneck burg (but not possible until housing market recovers w/o giving my house away), and buy a home with a more appropriate listening area of say 20 x 15 or so. So, I either buy another speaker system that is more appropriate for my big listening area now (and also works well in a smaller listening area I move to in the future), or hold off and try to tweak what I have now until I can move. Speaker systems I have had my eye on are used: Devore Nines, Zu Essence, and PSB Synchrony's. It's probably best to wait until the reseller market matures anyway for these speakers, as few are going to be put up for sale by their original owners for a year or two at least. The speakers are still relatively new to the audio market.

Adding a good sub is certainly an option if you like the speaks but they just are too small to pressurize the room.

"Why not consider something like a used pair of Klipsch Forte II? "

I have and still may some day.
