Mark Levinson 27 Clipping

Do NOT play loud. At best, you'll blow the fuses on the ML. HOWEVER, if you hit upon a very fast transient, more damage can occur -- as stated above -- to the ribbons on the Duetta (not easy to fix nowadays)... the fuse might not cut the signal off in time!
The Duettas are not as bad a load as other Apogees (i.e. they're less "bumpy") -- but I still used to send a Krell 80 into shut-down on orchestral pieces and no, the volume was not all the way up-- far from it :)! Happy holidays!

I don't know what the specs of the Apogee's are, but I ran my ML 27 with Thiel 3.6's, which are 4 ohm speakers rated at 86db and never had a problem. It played them loud and clean.

Thanks for responding (this site is #$@*&+ great). A rep from Audio Consultants in Evanston IL emailed me w/ the following,"The 27 has a soft clipping circuit and other protection circuitry, so there is no danger here". I suppose the speakers might be on thinner ice than the amp during a clipping episode. My experience w/ Scintillas and Duettas (tho' brief) seems to parallel Greg's. I've heard things start to choke even w/ some pretty testicular amps at way lower than a live performance volume.

Duane, the Duettas are a MUCH kinder load than the Scintilla... Duetta is a load; Scintilla is a short-circuit :).
Merry Xmas everyone!

Ditto: I also ran a 27 into Thiel CS 3.6's without any problems. The No. 27 has extensive protective circuitry bult in. If you have any further qustions, email Madrigal.
