@vinnydabully This is what Franco Serblin has wrote about the amplification for Acccordo's (in case you have not read it somewhere already)
"Let me clarify some issues related to amplification for the Accordo. These speakers have been designed to be as transparent and dynamic as possible. In order to successfully achieve this objective I have used a unique woofer with a long-stroke diaphragm and low resistance bass-reflex loading designed to offer the best impulse response. Although the Accordo can be driven by any amplifier, we recommend amplifiers with low output impedance and medium output power (40-70wpc into 8Ω and 80-150wpc into 4Ω). Too much power may result in excessive cone excursion and deterioration of signal quality. If we use the Accordo with a tube or Mosfet amplifier with high output impedance we may end up with not fully optimal bass control and again encounter uncontrolled cone travel. Needless to say that tube amps are generally not too good in this regard. I personally use the Einstein integrated amplifier which is nice sounding but without bass as good as transistor amps." - Sincerely, Franco Serblin
I can only add that I have heard Accordo's sounding great with 80w tube amp as well and obviously you know what you are doing when using your 'artillery'...
