I use to own and have heard many Energy speakers, and have used numerous amps with them. My favorite match has been the Odyssey Stratos with the 120,000 cap upgrade. Amazing amp. Smooth, dynamic, extended, superior imaging and depth that doesn't get conjested in complex passages as most all amps in this price range do, it is detailed, fast, very well build with a 20 year warranty and did I mention smooth. Vocals can be erie they sound so real, full, fleshed out, instruments can be in your room right next to you, you can reach out as if to touch them on good recordings. Not sure how it will mate with your preamp, which will also have a dramatic effect on the sound, as will your DAC, but if your system is lacking you'll find it will not be a fault of this amp. New they can be had for about $1300 to your door, used they are usually around $900, they have fabulous resale value.
