Shindo?

Simao,
Shindo offers amplifiers of various power ratings, I would think there would be an amplifier in their lineup that would be suitable for your speakers. I would look more deeply into this situation, you may be glad you did.

Rcprince,
No one could argue with your sound advice, home auditioning if possible is always the ideal way to proceed, problem it's often easier said than done. I am somewhat surprised that their 40 W amplifier would struggle with a 90 db speaker, it raises the issue concerning power supply stiffness and output transformer quality (I would expect top quality from Shindo). I have used a 40 W push pull el34 amplifier with 91 db sensitive speakers(12 ohm) in the past with no problems, it was a very good match.
