@coop_301 , Just to clarify; that with the Thiel’s sonically I’d much prefer the ML to the Crown or Eagle, and many others too. Which is not to say those amps might not be preferable with other speakers. The Eagle would be a great match with more reticent speakers (Vandersteen’s come to mind), or if one needed very high volume levels in a large space; the Crown could be just the ticket.
i can’t speak to the BAT amps I will say that at one of my preferred dealers who had the then entire lineup on display; when just approaching the volume controls on each and every pre, a rush of static ran through the speakers connected to their respective specific set ups. I immediately lost interest in the brand.
