Mono Block tube amp or Stereo Tube amplifier?

Need to know more about your loudspeaker.

I am using Legacy Audio Focus 20/20 speakers, and I have McIntosh C2200 Preamp, McIntosh MC402 amp, McIntosh CD player, and VPI Scout turntable. I am considering Bi-Amping, with tubes driving the Mid/High, and the MC402 driving the woofers. So that is where I am hang up between getting a mono block tube or stereo tube amp. I do realize that I have to use an active crossover in the Bi-amp configuration since the amps are different. Any thoughts on Mono blocks tubes versus stereo tubes amps for this application?

Larry,

I already have a preamp and a solid state amp (McIntosh C2200 and MC402 respectively), and I see the the Onix SP3 is an integrated amp, therefore I would not need it. Can you recommend another Tube amplifier in the Onix price range?

My experience has been that the big game animals of audio usually recommend mono blocks.

Start with why you want tubes. Then think about how much you can spend. Personally I believe that tubes are for acoustic music. I see no reason why anyone would benefit from reproducing heavy metal at 95 db with tubes. That is SS territory. Tubes are for sensual, subtle sounds.

If you still think you want tubes, or if you now see bi-amping with SS works better for you, the rules are the same. Two chassis cost more than one. Monos enable you to shorten speaker runs. Monos, even if they share a chassis will have separate power supplies allowing for better separated channels. Then there are layout implications, bragging rights and forum topics.

Remember, though, that bi-amping is not a goal but a means to reaching one's goal. Unless you need to do it, don't bother.
