Vienna Beethoven, Spendor 8SE, Adagio or VS VR4jr

Hello Audiophile friends,

I am looking for advice on how the following speakers
compare for when playing only Classic Rock at medium
sound levels. I don't play loud but do enjoy a medium
volume level. I am looking for refined sound, that is
not "cold" but maybe warmer and a little rounded. (but
still very refined in the bass and mids) The music I
listen to is the likes of The Doors, Eagles, Journey,
Tom Petty, Rolling Stones, you get the idea.

I am looking to buy used and would like to hear opinions
of how the following differ in sound or whether they match
the characteristics I described above:

Vienna Beethoven Baby Grand
Spendor 8SE
Acoustic Zen Adagios
Von Schweikert VR-4jr

From what I have read these are all refined sounding
speakers that go for about $2000 used on Audiogon.

My room is 12.5' x 25' with 10 foot ceilings. Hardwood
floors. The Speakers are on the 12.5' wall and I sit
9 feet back from the speakers. My Equipment includes
Krell DVD Standard, Krell 400xi Int amp, and a Unico Int
amp. I haven't made up my mind which Int amp I like
better so I use them both depending on my mood.

Who has heard all these and can compare them for me?
Thanks so much in advance my audio friends..
