Vandersteen Moel 2Ce better than Model 1B used in midsize room

As far as sound 'getting  muddled'.
I would look upstream. Your NAD is a decent amp.
What is your preamp and source and cables?
Audionoobie's Belles Aria is a great combo with Vandy's. I run a pair of Aria monoblocks with my VLR's. They really put my old McCormack Micro amps to shame. 
Also, preamp and cabling will make a significant difference in what you are hearing.
Please, don't think I want you to buy more equipment, but my opinion is that if you aren't hearing complex passages, then there must be something wrong upstream, because I know the Vandy 1's can perform as well as the 2's with regard to complex music. The only other factor would be if the speakers are in need of repair.

looking at your attic photo...cool room - some challenges and opportunities... love it by the way...

your NAD has enough grunt for either, obviously you could change it to some benefit. with your space, i would high pass the 1’s and add a Vandersteen sub. IF you put the 2’s where the 1’s are currently you will get the benefit of the midrange for sure BUT the acoustic coupler is too far out from the wall to have much effect....hence my recommendation.

have fun, enjoy the music !!!!!

I bought a pair of Vandy 2ci with sound anchor stands.How far do you tilt the speakers.Mine are playing vertical now.

Follow the manual instructions to the ‘T’. If you don’t have the original, download a copy off the Vandersteen web site.

@audionoobie

Don’t find you contrarily because this is exactly why i have a bit of doubt.

Let i put it like this. The 1B is performing whit let say 70% of my music which is Jazz small ensembles but also jazz rock like Steely Dan as a dream. Basically hearing Chet baker (most of his albums) they create an intimacy (staging, detail, clearity) that is unbelievable. Till now i did not have this experience with any other speaker brand that i listen to in my room an i had some.

Only when i play lets say Year of the Cat from Al Stewart it sound more or less flat. When i hear that i think would a 2Ce does that better or is the recording such that the information that I’m looking for is just not there/in (I do use room correction software that does an excellent job in balancing the sound) . Basically i think it is a trade of an you think the bigger the better specially when it is the same brand.

@gnrdbob

The NAD C370 is an integrated amp using 6mm ofc speaker cable an JK acoustics type 2 an van der hul interlinks.

Some years ago i did a measuring as you could see in one my pictures. As you can see there are peak difference from sometime almost 15 db thats a lot. I can assure you no cable, amplifier or change in CD, DAC can overcome this. So i start first with some wall an ceiling treatment for my monitors that helped for about 15%. Than i used room correction software (Mathaudio Room EQ) that changed the sound more than 70% for the better it is completely balanced using the flat target curve.

I’m now 61 did spend quite a lot of money in decent gear but i never had this experience with Room Correction software the best money i spent was 80,- Euro buying a measuring mic. I don’t think the B1 is broken however it is difficult too reach the drivers but i know that the drivers have rubber surrounds not foam an they sound very tight when needed.

Yes i was also thinking about adding a sub woofer however i don’t have a problem with the tight bass that is now present in the B1
