Vandersteen Treo vs 3A Sig as upgrade

Great thread everyone....have read it all. I was just introduced to Vandersteen speakers.  Fantastic in my opinion. Unfortunately it was the Sevens and Quatros, which I can't afford!  But, I could afford the Treos or Treo CT, but haven't as yet heard those. I have a store nearby where I can and will audition in the near future (San Diego). 

Question:  I have a Line Magnetic 518ia...22Wpc. Would my integrated amp be adequate to drive the Treos?  I'm not interested in changing out my amp at this time but loved the sound of the Vandersteens I did hear and I'm sure I would like the Treos after reading this discussion (not a big bass head).  Would the Treos even be viable option given my current amp (current speakers are PSB Imagine T2)?  I listen mostly to vinyl (Prime and Lyra Delos through Manley Chinook) -- soft to classic rock, jazz mostly. 

Thanks for any feedback. 

ekimg The Treos are only 85 db efficiency. I have no knowledge about your particular tube amp but even 22 TUBE watts sound a bit lean for the Treos. Perhaps you could take your amp to the dealer to find out?

Agree with @hifiman5 ; just for s&g, try out those 22 tube watts with a pair of Vandersteen 1s.  You'll be surprised by what you get for ~$1250.

Anyone in San Diego looking for 3A Sigs please check my ad on USaudiomart. No shipping (no boxes) but will make you a killer deal.

hifiman5 -- yes I will have to take my amp in and see how the Treos respond since he does not carry LM gear.  Thanks for the suggestion. 

cedargrove -- if he has the 1s I'll try those too...thanks.
