Anyone using Levinson 27.5, 23.5 in bridged mode??

They can be purchased relatively cheap and will give you a great deal of power, but what happens to the sound?
I asked the same question last week but got no answers.
I currently use a 27.5 and it is an outstanding amp. Some
feel it's even better in sound than the 23.5, no slouch
by itself. However I'm looking to increase power for my
Magnepans. According to the owners manual, a 27.5 bridged
will output 400 W/Chan @ 8 ohms. If the sound quality did
not suffer, it would be more cost effective than selling
the 27.5 and moving to a 336.
just want to hear from someone on this ?? chuck
