I'd be careful about power. I home demoed a Prima Luna Prologue integrated amp with my Synchrony Ones and it was a complete disaster due to a lack of power. It distorted piano notes at what is a moderate level for me and couldn't even begin to play electronica. I use a Rotel RB-1090 ss amp rated at 380 WPC into 8 ohms and the Synchrony Ones are closer to four where my amp puts out around 700WPC and it doesn't seem like overkill to me at all.
