That's right,
It is the dream speaker for some of us, but your questions can be answered only from someone who has the Latour in his system. So far it seems no one purchase the Latour or even the Shindo 604 (another marvel !) and I think it's a real shame people who can afford these mind & soul saviours, to prefer the usual hi-fi(ish) suspects.
My experience (for about 5 times of 4 hours) with them, is that they need plenty of room to breath their magic & in case of the 604, I think that a DHT SET mated with passive pre it brings the apparent delicacy. Also, I would prefer a lighter-airier source than the Shindo arm/table.
All that said, they are the best ever made speakers that I have the pleasure to audition.
I wish you with all of my heart to put them in your life.
