I have two setups. For most music I use a straight Odyssey Audio system. Khartago SS monos, Candela tube pre, and Kismet Reference floor standers. The SS + tube pre is everything I want. I’ll spare you the colorful adjectives to describe the sound. I thought I had experienced good system synergy in the past. And then I listened to the Odyssey system. I listened before learning the price. I almost didn’t believe it. My other setup is Emotiva Stealth 8 active monitors for super accurate, fast and crisp listening (electronic/heavily engineered music). They’re so good. Sometimes I add the tube pre for some sparkle to the sound. I like the way AMTs sound with tube gear.
Edit: forgot to mention that I’ll pull out the Willsenton R8 from time to time. I like it best with the Klipsch. I lose a little something when I use it with low efficiency speakers.
