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?

Vandersteen speakers are not woolly or veiled, nor are they hard to drive. I once heard a pair of the model 2(something) in a small room driven by Quicksilver monos which used, if I remember correctly, EL34 PP producing 30/40 watts. The resulting sound was extremely pleasant for an affordable partnership. They are not detail monsters but do entertain for extended listening.

I have heard Vandies many times, one occasion with a pair of huge class A Sugden Masterclass mono amps belting out lovely sound at high level from the model 2 in a large hotel room at the closing of last day at a show. They filled that room beautifully and without any sign of strain.

Take cognisance of the suggestions to improve the source. A computer with Dragonfly output is going to disappoint. Replacing your speakers as some have advised will merely give you a different perspective on the inadequacies of your existing source. The most expensive speakers introduced to your existing kit will simply more accurately reveal your problems.

The Vandies may not be for you but right now IMO you are not in a position to make that call. It's the well known garbage-in-garbage-out story.
@ OP,  just noticed this from Absolute Sound, where your speakers feature :

Wow - thanks to all for the feedback/input. John Rutan was very kind in reaching out to me - we've burned a couple of hours of his personal time on placement changes based on my not-so-perfect space with SIGNIFICANT improvement.  Kudos to John - super helpful, super nice.  We've talked through many details and following through with a needed repair/upgrade on the Apt, cabling improvements, etc. - going to knock off variables and stay the course for a while.  I highly recommend John - he's really helped me in re-learning this hobby after being away from it for many years.  Thanks to John and everyone that has chimed in - hope you all continue to enjoy the journey.
So happy for you. Glad you talked to a pro who uses the. Daily as well as other lines. Set up is so key to any speaker. 
Nothing was done in repositioning that can't be done with any other speaker. It's not the long term solution if you are not liking a speaker. Within a week you will adjust to it and you'll be back at the same place again with criticism.

 There are many thin slice ways to affect speakers. That doesn't resolve the larger issues with them. Just because there was a change doesn't mean a particular speaker is anywhere near the potential ideal. This is one of the biggest mistakes that is made continuously. It does set up a sale for the dealer, and if he has put in the time and effort, he deserves that consideration. You would get superior sound moving up the line, so that is another alternative. But, until you get other speakers in there to compare head to head, you have no idea what you're doing. The dealer will push his line, no surprise. 

So, you will be throwing money at it, with an upgrade, new cables, etc. That is an expensive way to learn, but there are not too many other options when one does not have experience. Try to keep it as fun, not frustration. Vandersteen, especially lower end, is a polite speaker that will not offend. Whether it is involving enough over timer you remains to be seen.   :)
