Art, how would you describe the sound of a Rega floorstander? I know you said the sound is on the thin side, but do they have enough guts to play significantly louder before reaching their limits than the typical standmount speaker can? One would think with the extra woofer the speaker shouldn't be too thin sounding and could crank a bit.
I have my eye on the RS5 (or RX3/RX5). Ever since I tried the PSB T55 in my system, I realize I am missing the ability to turn up the volume to levels that really pressurize the room. But I'd like something a little nicer than the T55 in my stereo setup.
At the end of the day, I will likely stick with my 118's. While I'd like that extra oomph, they fill the room fine and they do everything else amazingly well. Plus, augmenting with a sub will do the job. But Rega floorstanders have me intrigued. I may try to get a demo at a local dealer.
