B 1000f or 2X M-900u

What do you think are the advantages of an monophonic, for a very low sensitive(81) and very low impedance loudspeaker, minimum around 1,5 Ohmn.
Best regards

2 x Lux M 900u

I own the Luxman M-900u, but notice that when run in mono mode it's only rated down to 2 ohms. Since the B-1000f is designed as a mono amp and rated down to 1 ohm, I suspect it might be better suited to your 1.5 ohm load.

The M-900 sound impressively musical,but i have heard lose all that magic in mono, I never listened the B-1000f.

The M-900u is a bridged design when operated in mono mode, so 1 ohm -> 2 ohms BUT ALSO 150W -> 600W. Most users that I've seen on forums seem to think that upgrading from stereo to monos yields a big improvement in SQ. Germanchu, what is the nominal impedance of the referenced speakers?

My loudspeaker are a pair of Dynaudio Consequence, and the nominal Impedance is 4 Ohmn.
I have read and listened at Audiolab that M900 is a perfect match for Dynaudio C4, perhaps the sinergy will be possible with the very difficult consequence.
In the public presentation Dynaudio drive it with a very very powerfull and expensive Arbbiter Amplifier.

At home my actual amplification is a pair of Cello Encore,with no enought power to drive it.
With the Cello the sound is bright and have not enough bass.

I would think the Luxman monos would be fine for normal use. If you can't find a reference for this configuration, you might consider contacting Dynaudio.
