The Reynaud's I am familiar with are more line tunnels than transmission line, but I gather you have all been over these differences.
I haven't read the entire thread, but I heard the VSA 4 Juniors in the same room on the same day as the rest of PAAG. It was a small room, about 13 by 17, totally untreated, without a lot of speakers on display. The Ushers were close to the side walls. Both pairs were within about four feet of the wall behind them. I listened via the 30 wpc Granite Audio tube integrated and one of the Granite Audio CD source units.
The tonal balance and sound stage seemed way off to me. There may have been a hint of that snap others have alluded to. I cannot believe the 4 Juniors were sounding their best in this situation, but only based on hearing other VSA products in show settings.
Just for reference, the DB's in their larger room sounded better to me than the 4Jr, but not nearly good enough for 8k or whatever, imo. No deep bass in particular. (Others disagreed with this last judgement....)
