"Are you sure there are no tubes in the chain?" I asked On a Higher Note's Philip O'Hanlon, North American distributor of the BBC-inspired Graham Audio speaker line, in Montreal retailer Art et Son's room. Philip was sitting with me listening to an LP of Belgian singer Mélanie De Biasio.

MartinLogan's Motion F200XT in the Planète Haute-Fidélité room wasn't the only speaker in town to employ a Heil Air Motion Transformer tweeter. So did Monitor Audio's 3-Way Platinum 300 3G (for 3rd generation) floorstander ($22,000).

Remember in my first post when I said "How cool it would be if I'd turned into Alternate Rob with a half-million dollar system waiting for him at home?" Well, the system I encountered in one of Filtronique's rooms would fit the bill nicely.
