I agree that the Harbeth will have a different mid-range sound. You can probably find a used pair of Vandy 5As for close to $6500 or less at this time so that may be a great option.
Since the Quattros have built-in amps in each speaker for the subwoofers, your amps will only be driving the mids and tweeters (using the hi-pass filters) - completely false statement. Increasing the power supply capacitors in the amplifier we build also added to the bass improvement in my 5As.
The Vandersteens do so much right and can be adjusted for your room now and in the future. I do miss the mid-range of my Alon V MKII speakers though in direct comparison.
I also built a pair of the HP filters for my 5s, the original ones to me use basic parts which I upgraded and now they sound much better to my ears.
Happy Listening.
