Mccormack DNA-1 deluxe or gold 225 immediately comes to Mind...give one or both an audition. Steve McCormack's idea of utilizing his Distributed Node concept placed the power capacitors near each discrete transistor. Instead of two massively large capacitors, the smaller caps were thought to give better pace and lighting quick response. Admittedly, this was circa 2000, but hard to argue against after hearing this transient response. I think you'd all agree amplifiers in general represent a mature technology and some of the best ideas are time tested. Give one of these a listen....and thank me later:)
