Vandersteen 5a, 15 years old vs. new Vandersteen Quatro Wood (upgrade or downgrade)


I currently have a Vandersteen 5A purchased about 15 years ago in great condition. My  equipment  is Thor 150 watt  tube EL-34 monoblocks with a Thor linestage, Sony SACD player and a middle of the road VPI turntable. Was reading about the Vandersteen Quatro Wood CT which I believe retails for $15,000.00. The wood has the carbon tweeter, my 5A's do not. The Quatro also has a 250 watt amplifier for the built in sub while my 5A's have a 400 watt amp.  If I purchased a new Quatro Wood and sold my 5a's would the resulting sound be better overall in my 8 1/2 by 15 foot room?
 My rationale for considering this upgrade, is that I would be getting a speaker with all new parts and would obtain a new warranty.  Any thoughts would be helpful.  In short is todays' Quatro Wood CT a better sounding speaker than my old 5A?  Would this change be an upgrade and would it yield an improvement in sound to justify the cost?

Thank you.

I spoke to OP and we scheduled a dial-in. There are always folks that know a lot about what they don’t know a lot about. When Vandy’s are tuned 4 inches from the wall ""couldn’t believe it myself "  taught over 20 years ago by RV can then spread speaks wide apart adjust 22 pots, analog room compensation pull-down excessive bass bloat at room’s resonance, perform correct tilt-back address first reflections they are truly awesome.

I really have to get those Sub 3's for my Treo's. I think the equalized bass is going to be a game changer.

Hi Johnny R

i am so so glad the OP called you for a tune up ! I woke up in the middle of the night running his room node calculations in my head - I know you know this, but for others, max cut on the bottom 2 potentiometers can be a great trick also !!!!

wishing you well brother 
Also send me or post up the post EQ results, which will shock even the rational :-) big fun
