I have owned an audi0o refinement complete. But recently sold it to buy an audiomat arpege tube integrated. The complete is ok but was completely outclassed in all respects for less money there is a passion audio integrated tube for $1100 that destroys the complete . I think there are some reviews at www.mutine.com and a reviewers choice review of the audiomat at www.soundstage.com I know That www.fidelisav.com sells both products. also www.theabsolutesound.com has a four way review including the ECI-3. Do yourself a favor and get the audiomat. Chel
