To JP1208 which version where you comparing the Klouts to?
The older Ref 9 were good but hardly the world class amplifiers they are now.
I would also agree with you that the A21 vs the Nuforce is silly. We have compared the Ref 9SE V2 to a $21,000.00 state of the art solid state amplifier that is rated as one of the best sounding solid state amplifiers in the world, and many of my customers prefer the Nuforce, yes they are that good!
I am quite familiar with the Klout as I used to work for one of the biggest Linn dealers in the country, and I liked the Klout so I am interested in the particulars of your comparison.
