Many of these seem not to be widely available in the US...is this a Cdn or Brit magazine of website nominating these?
I own the little Quad 11L and it's good for $700...but I think the various Brit mags overrated it a bit (the finish is scintillating, tho). I don't think that much of their lesser priced stablemates, the Diamond 8-series from Wharfedale, either (tho the entry price of under $300 on the first couple models seems to be a better value proposition than the Quad 11L).
I heard the Quad 21L (floorstander) at the recent CES Show....and again came away mostly unimpressed for the money (I can't remember exactly, but it was north of $1000). The electrostatic 988...ah, now that is another story entirely; but for $9000 it darn well should be.
Different likes and dislikes this side of the pond I guess.
