The Monacor unit linked to only goes out to 40Khz which does not really qualify as 'super'. Try to find a tweeter that goes another octave higher to realise the full benefit of the extra information.

If possible try and borrow a pair for a taste of what they can do. Townshend makes excellent ones but very scarce on the second hand market. Seems people don't let them go easily.
Why don't you try them out on your pet cat? Cats can hear up to 64kHz.
