Add a Subwoofer to my Vandersteen 1ce s or replace with Revel Concerta2 F36

@voodooman13

Upgrading speakers will likely be the most immediate path to getting significantly better sound. The F36 is a nice speaker, but you have other options. You owe it to yourself to visit Destination Hi Fi in Los Angeles and listen to a set of Legacy Audio Expression. The Expression offers a ribbon tweeter and 38Hz bass extension, and weighs in at 70 pounds, while the F36 weighs 50 pounds. The Expression has 8" woofers vs 6.5" woofers on the F36. The Expression will give you the low frequency dynamics you mention, in spades.

For a real tweet, while you're there, have them connect the Expression to a Raven Audio Osprey tube integrated amp!

BTW, I'm pretty pleased for now with the audio quality I'm getting via my Denon X5200 receiver, paired with a Krell FPB-400cx power amp for the front L/R channels, and my Legacy Audio Signature II speakers, which are from the 1990s. I think you can get some pretty good sound from a package of your current receiver, separate power amp, and a significantly upgraded speaker such as the Expression.  You can always add a higher quality pre-amp later.

Thanks again to all who have replied. Sounds like I will be listening to some Vandy 2's as well. After all it was Brooks Berdan himself who told me about the 2's back when I was just 19 and purchasing my first Rega Plannar 3 with Sumiko Blue Point set up by Brooks. I did like the sound of the Revel F36 with the Rogue Cronus Magnum II, but also heard shrill highs that seemed like eventually could be fatiguing, I also discounted that to possibly "still breaking in." Anyhow, really solid advice guys thank you.

voodooman13-

The Vandy and Revel are (2) different speaker designs. Spend time w/ both to determine the model that is right for you.

Agree with jafant.  Listen to the subtle dynamics. Listen to the sibilance (John Mellencamp stuff is good here).  Listen not just to amount of bass, but also the quality of each note.  Which gives you a real sound stage.  Does the sound stage stay big all the time or does it change per recording?  I'd listen to well recorded music to see which one is better and then to other stuff you just love. 

It will be very hard to make a decision without have them in your own house side by side and all but make some notes and listen to the same recordings.  Get to know the cymbals and piano and then male and female voice etc...  Where are you sitting in the hall....I never understood components that put you IN with the band or orchestra, lol.  

Have fun with it all and listen as a system to make sure it's what you can get out of your own.  Also listen with top of the line components to see how much better your speakers can sound as you upgrade in the future.  Keep us posted.  Two speakers you list are a good start for sure.

Well, I hate to be a stick in the mud, but if you are considering the Vandy 2's, I suggest also looking at the Treo's. I bought ctsooner's pair after owning the 3a sigs. It was a good move. I like the more stylish design as well as the improved performance.
Since you feel you need added bass, perhaps the Quatro's would be a good move. You wouldn't need to add the 2w/2wq subs and their footprint is identical to the Treo's. 
Though I know you have a budget, and spending $4-5K might seem ridiculous, just remember that if you are buying a pair of 2sigs and a pair of subs, you really aren't spending that much less and you will be ahead in terms of upgrading.
