Amplifier pairing for Altec Flamencos

Thanks for your input.  Do you think your new class D mono blocks would be a good fit for the 16 ohm Altecs? Or should I stick with a tube amplifier for this speaker? I think my current tube amp falls within the parameters you outlined, but it is the only tube amp i have ever owned so i have no reference for judging its performance.  

@jplunkettj My speakers are also 16 Ohms and they work fine with the class Ds. A good tube amp will work fine too.

I have also been utilizing an SVS SB 1000 with them. I am not positive that my current amp is affording the old Altecs the level of dynamics and resolution that they are capable of achieving.

@jplunkettj FWIW, the dynamics should come from the signal source, not the amplifier. Resolution is a different matter; that comes from low distortion. You're not going to get that from an SET; while they can be quite musical, they lack the resolution that you can get from a good push-pull amplifier (note the use of the word 'good').

Your Altecs are about 97dB; unless you are in a small room you'll find that 6 Watts isn't enough. My speakers are the same efficiency and my room is on the small side. I like to have at least 50 Watts available. You don't want to push any amplifier hard as the result is more distortion (and harsher sound due to increased higher ordered harmonics generated). If the amplifier is loafing (and you're using tubes) the tubes will last longer and the result will be more musical.
