Not sure what your amps are capable of in terms of power or current, since you did not specify a make or model, nor can I figure from the website what specs the Spendors have. I can say that ATC speakers are among the two or three best speakers I have heard with respect to reproducing realistic dynamics, though I was listening to their powered versions of the SCM 40s. I can't speak to the Spendors, having not listened to them, though they have a reputation for being very natural, musical speakers. Hopefully others who own them can help. What do you value most in a system--musicality, dynamics? That may help you in making a decision.
