Paradigm Monitor 5v2 - Studio 40 v3 - worth it?


I'm planning to upgrade my Monitor 5 V2 with premiere S-series stands & NAD c320BEE int. amp within the coming weeks, I am thinking of just making a step up the ladder to the studio 40s with a higher end NAD int amp also (c352/372).

Anyways, I am wondering what you guys think about the studio 40 v3s vs the monitor 5 v2s? Is the price difference worth it? And what do you recommend for amplification for a room about 15x20 in size.

the pma 2000ivr ($1200) is based on the s10 ($5200) which is based on the s1 power amp ($20,000)i think it is a monoblock that would make it $40,000.
the 2000ivr is a powerfull yet musical amp on the warm side of neutral. the weak link is it's preamp section thus the reason i use the dodd audio preamp. you can check out what danny richie ( gr research) and gary dodd ( dodd audio) had to say on this combo at audio circle under north texas audio jam, dodd audio jam session.
