 Although I like the sound very much and general quality in the Petrof I have 
noticed significant compression ridging in all the one I've seen on dealer 
floors and homes. I'd venture it had the ridges before it hit the clients floor.
    I've used the same spruce panels as Petrof  and found it to be a very 
brittle wood. Or at least it was the spruce Geneva international sold as Petrof 
European stock. Of all the spruces I've worked with I least liked this variety. 
It would split and crack along the glue joints with out much encouragement. 
Or elsewhere.
    Obviously the panels are being dried to much for many parts of the USA 
(all Parts) The dealer needs to get his head out of the sand as to the 
damp-chaser isssue. I mean get real Dude.
