Considering Vandersteen 3a Signatures


I have Spatial Audio M3 Turbo S which I enjoy but was recently considering trying the Vandersteen 3a Signatures.  I love the soundstage and the holographic feel of the Spatial's but I'm seeking greater clarity in the treble and more detail in the mids.  I am driving these speakers with a Rogue Audio Cronus Magnum with KT120 tubes.  The source is mostly analog via VPI Prime, Dynavector Karat and Parasound Halo JC3+.  Also digital via Auirender N100 and Schiit Gumby.  I listen to a wide spectrum of music, but mostly in the rock and jazz genre.

Should I expect a major difference in sound?  Any other ideas for speakers that would fit the bill?

I have Vandy 3A Sigs.  Would never think to call the tweeter sibilant, but I suppose there's plenty of room for subjectivity in that call.
I just noted a bit of grain and spit with some recordings that I don't hear in some other speakers. It's plenty detailed but not the most refined metal dome I've encountered. It reminded me of Monitor Audio's aluminum dome tweeters in that regard. Anyhow, the Spatial compression tweeter/mid is more refined - sounds similar to beryllium tweeters.
Thanks, everyone.  I truly appreciate the advice.  I was considering both focusing on room treatments as this is something I have yet to explore and considered some tube rolling with the Cronus Magnum.  As tomic601 noted, "enjoy the music"
I have the 2CE Signature II and love it the details and clarity is superb and if it’s set up and place properly, the sound stage is overwhelming. The 3A Signature has everything the 2CE Sig II has, and one step above as it has a better bass than my 2CE Sig II, I highly recommend the 3A Signature.
The 3A Sig should have the better mid range driver (that is being used in the quatro and Treo) than the 2ce sig 2, as well
Do room treatments. I'm using Primacoustic panels from Sweetwater Sound in a moderately small room with Vandy 2Cs and the difference between untreated and treated was jaw-dropping. Bigger improvement than ANY gear change will do. Remember, the room gives half of what you will hear, (maybe more). And yes, I LOVE my Vandys. Also, agree 100% with tomic601 to get Jim Smith's book Get Better Sound. Indispensable tool to get the best setup to play the room. Finally, I also think you should get the 3As, but that's just because I like Vandys.
