I am also from Ontario Canada,and used to own two pair of 57's which I stacked, so you can see where this is going.
Buy both pair, compare them and then if the modded pair sound better get the other pair modded from the same fellow.
Believe me, the small cost of a DIY frame(check the Quad esl sites)and the cost to mod the second pair(if needed)to give you a balanced stack will be worth every dollar and then some.
Stacked Quad 57's are a real treat and if more people could hear them, no one would settle for just a single pair.
I've been an esl fan for years, owned the 63, the stacked 57,several CLS, and now on my second Acoustat 3,this time the right way with the tube servo amps.
There's something very special about stacked 57's that set them apart from all the other speakers I've owned, and mine weren't matched.
If you can swing it, buy both pair.
I should note that I have no affiliation or knowledge of the Quads you are speaking about.I regretably sold my stacked pair about 7 years ago.
