How about an amp that covers the basic fundamentals like the ability to maintain linearity, accuracy (to the extent possible), speed/rhythmic drive, low noise, continuity and flow, dynamics of the micro as well as MACRO variety, high efficiency/reliability PLUS the ability to:
1) Scale between analytical to neutral to musical/tubish warmth on the fly per the listener's preference and/or source material dictates
2) Choose power level (wattage)
3) Modular and upgradable
4) On the external side: choose your own armor that better fits one's style (more choices beyond the typical color options) and preference. The better the build, the higher the cost, vice versa.
A more unique, customized solution instead of the typical cookie cutter approach. Is this possible? Oh, still be real world, reasonably priced.
