First question ,most important,
what speakers are you using,, and their efficiency. Then you can say here are choices for most wpc is not the best
audio Flight ,great hand built Amplifiers from Italy Solid State very high current
$4k integrated ,on Audio gone you can get for maybe $2200. This refined detailed sound . I owned a audio store
for years synergy counts ,you start by listing your whole system , just amplifier
or maybe a integrated amp,vacuum tube, solid state, class D ?
