Not Thrilled with Vandersteen 2CE Sigs - where is the first place to work on?


Trying to build up the system this year, bought some Vandy 2CE Sigs.  Have the anchors, following instructions for placement, built bass traps and a couple of acoustic panels in my medium-sized but odd-shaped basement listening area - still not thrilled.  Using laptop with Tidal and Dragonfly Red - and some stuff sounds GREAT (Steely Dan, SRV, Beck, Dire Straits, Wilco) - but disappointed in a lot of other stuff.  Some objective opinions on where my issues might lie?  Expectations too high? Hearing the truth of production variations?  Running an NAD C272 at 150WPC and an original 1979 APT Holman Pre Amp.  Not MAC, Bryston, etc - but was expecting more.  Thoughts? Rebuild/recap the APT?  Amp upgrade?  Where might the low-hanging fruit be?

I would eliminate the laptop and the dragonfly first. 

Steely Dan, Dire Straits, ect recordings will always sound better than a lot of other recordings.
Although probably not the main culprit, the Dragonfly Red is a singularly uninspiring DAC.  It's missing low and high frequency extension as well as dynamics and punch.  I replaced it with a very old PeachTree DAC-IT (the original version) and heard an immediate improvement. 
Had a pair of 2CEs that worked well in a medium-sized room but not so good in a small room. As others have said, they need room to breathe. The listening position also needs to be 9-10 feet away (min.) for a proper blend of the drivers.
I had 2ce with McCormack 0.5 amp and tube preamp. Did the setup according to the Vandersteen manual and talked with John Rutan (thanks John!). Ultimately, to me they were more veiled on the top end than I cared for. Sold them extremely cheaply to help out a young audiophile friend just out of college and he loves them to this day.

I would recommend you take tomic601 up on his offer and pm him. He seems very knowledgeable and a great guy also. 

 I think we could be dealing with two different potential situations here 1) It is not possible to have significant problems in a system and have some recordings sound great especially when they are known great recordings. You could change some of the components in the system and improve the sound but the fact that some great recordings sound great is meaningful. 2) you could be chasing recording quality and the only way to deal with that is to use tone controls on the recordings that need them or dumb the whole system down to the point that everything sound OK by trying a speaker with many drivers that smear themselves, a dip in the mid range, plenty tweeter(s) and up in the bass that play loud as for some audio enthusiasts enough volume cures all. I would sort this out before spending any more money because even though several hundred thousand of these speakers have been sold they are not for everybody. If you decide to keep the 2Ce Sig’s I can help you get the most out of them cost effectively.
