The best thing to do is call up Verity. I have a sneaking suspicion the Rienzi's will be too small for your room. I had the Fidelios in a 17 x 20 room and while they sounded good, they did sound small. If you are buying new and can afford good speakers, then take your time. I've spoken to Verity before and they're straightforward and helpful. Since you mentioned the Leonore, I'd investigate them. The 509u doesn't doesn't have a remote, in case you need one.
Other speakers you may want to investigate: Devore Silverback Reference or something from Audio Physic. If you can handle the heat of the Luxman, then go for it. I thought it was stellar.
