Thanks Audiophiles, especially Bill, Stuart and Rob,
I am curious and call it my ignorance but can I use the Powered Sub
with a V2.0 Integrated Amp or does it need to be a 2.1?

This depends on the sub - most powered subs will accept L/R speaker
inputs, in which case you can use a 2 channel Amp with them. To
effectively integrate the sub it must allow you to set the crossover and
volume level. Again, most modern subs will permit this, but I'm not
familiar with the PSB sub in question.

Typically, you want to set the sub's crossover so there's a slight
overlap with the low end extension of the speakers, but what actually
sounds the best can take a fair bit of trial and error.

Ideally, you don't want to notice the sub at all - it should just seem
as though your speakers have great low end extension. Probably with the
floorstanders in question we're talking about a crossover set at
something like 40 to 50 Hz or so, but it could be quite different
depending on your room and where the sub is placed. Sub placement has a
profound effect on how it sounds.

Bottom line: provided this sub has the ability to set the crossover and
volume level and has L/R speaker binding posts you can use it with any 2
channel amp.

And, as I said in my previous post, it's entirely possible that the bass
extension of the floorstanders in question will be more than adequate
for you without the sub.
