I just visited Audioconnection yesterday.
Johnny was playing the VLR’s with the Belles Integrated and a Sub 3 subwoofer.
It sounded mighty fine, to me.
I owned the 3a sigs before moving to the Treo’s. Though not necessary, adding the 2wq subs really fleshed them out-seamlessly.
Though the Belles is only 75wpc, I think it should work- though you may not get earth shattering volumes.
If you do go for the Belles, I would try to add some subs at a later date.
Using the Vandy subs will help your amp perform by removing all the power consuming lower frequency demands.
