Thanks to everyone for the help!
I did order the Vandersteen 1ci's today. My plan is to stay-home and set-them-up Wednesday. The size, look, and (assumed) value were the drivers. I'm not certain about investing in NOS tubes for the PL because it does not have a remote control. But...I do know those tubes would make a difference. I still have the stock tubes, Audience power cables and inter-connects, and I have no idea why I did not insist on a remote when I got the Prologue!
If I'm pleased with the tone, the PL will probably stay. I read some nice things about the Rega Brio, but as-soon as you dig further you hit a vein of dissatisfaction with hum.
I thought maybe for less-than-budget I could get something that blew me away. The speaker eval will be interesting...
