At the show were the Arros paired with a tube amp? If they were, you should enjoy them with your amp.
I have Arros paired with a similar amp and it works fantastically. Not only do I get all the volume I need (somewhere in 90 db's peak in a room similar to yours), but the sound is rich and smooth. My amp is a Sonic Frontiers with 50 wpc from PP 6550s. Based on this, your amp should make a beautiful match with the Arro.
Fwiw, I am perplexed as to why the dealer would tell you such a thing. Is he trying to sell you something else? Does he not like tubes? Maybe it's best to ask him why he's negative about the idea--that is, if it matters to you!
I say, give it a try; I think you'll like it.
