I have an acquaintance that is a touring guitarist in Nashville. He runs two "Cleans" on his pedal board at 1/10th power each into an 8ohm 1x12 cab. That equals 5 watts per cabinet. He says the sound is huge without being loud. He's been a die hard Marshall user since the 80's and made the switch about 6 months ago. I just asked him about the setup recently and he is still really excited about it. He didn't start by running it in 1/10th mode... he said he tried it for fun at a sound check and was surprised at how great it sounded and never looked back.
