Advice on a Used speaker, Budget $4500


I just sold some of my speakers to thin the heard and try to step up to a better speaker.  I sold Kappa 9s, Dunlavy SCIVs, and Infinity QLS1s.  All of these were very good but I did not use them much.  In my mind I want to get either a Dunlavy IVa or V.  I am looking for a good all around speaker that does it all well, I know some speakers can do certain things better, but lack in other areas.  That is why I want the V's,  it is well known to do it all well.  It is supposed to have a nice balance.  The only thing that worries about the V, is some people say it takes allot of power and I may not have the amp for it.  I sold the IV's due to the lack of bass.  I know my room was part of the bass issue and I am in the process of having a professional help me get my room dialed in.  I listen to all music, but if I had to choose a preference it would be classic rock and blues rock.  I do love crisp vocals and if I had to pick a favorite instrument to listen to it would be the piano.  I know I like classic rock but then list the piano,  go figure.  By the way my room is very big around 500 sqft and has 8ft ceilings.  It is a basement man cave that my wife lets me do what I want with.

Here is some of the equipment I can use to power my speakers.
two Mcshaned Citation IIs
Two Mcintosh MC30s
A sumo nine
a Pass labs X250
Citation I preamp
Juicy Music Blueberry
The Dude pramp
Pass Labs X one

As you can see I have a variety of choices to work with because each speakers likes something different and it is fun to experiment with.
I would love to hear some opinions on what to look at.

Erik, seriously? You mean hundreds (not dozens or even scores, but hundreds) of dealers, professional reviewers, GET customers, potential GET customers and another category I' sure I'm forgetting are "wrong" in their assessment of the Triton line? PUUUUHHHHLEEEEEEZZZZZZZ

I won't debate this with you as you're certainly entitled to your opinion. As am I :)
So many great choices with that budget,  patience always pays off when buying used.  When I have a decent sum of money to spend on something I always look at it without cash on me, a pocket full of money can cloud my judgement .  If it was meant to be I will return with cash.....
Yep, Triangle and older Thiels got the same reception.  I certainly could not understand it.

Most importantly, I would not put these speakers as one's I would recommend without a long listening period.  Of course, it's your money, spend int to make yourself happy, and I'll do he same. :-)

Best,

Erik
FYI, a nice pair of SC IVas recently came up for sale in the Houston area $800 under your price target. 
Rock?  Something from the JBL synthesis line-up and a nice subwoofer for a big room.
