You don't need the extra wattage. Typical listening levels for most systems are just a few watts. The rule of thumb is 10X the average power to handle dynamic peaks.
Yamaha NS 5000 w/ NAD M33
Currently driving my brand new Yamaha NS 5000's with my new NAD M33. (and they sound relatively well paired!)
I am considering adding an NAD M23 (200w) and bridging it with the M33 (200w)
*but concerned it may be destructive to my new LS 5000's, (nominal 200w; max 600w)
Curious as to other more experienced users/dealers thoughts. Thank you.
