⭕ This is my pair of Theta Citadel 1.5 mono block amplifiers purchased new in July 2014. Less than 30 hours and used them to drive my Egglestonworks Andra II. They look and operate like new and sound fantastic. They surpassed my currents amps by a wide margin sonically. Soundstage is wide and deep, Imaging is spot on with amazing detail, air and space. Very clean, transparent sound. The amps is guaranteed to be like new. They are still under warrantee from Theta. Can help to ship and I have the original shipping boxes.
