Having had a lot of Gemini amps in the past i thought this would be a good fit for my home vinyl dedicated room. Oh How wrong I was, turned it on, the fans are unacceptably noisy, so much so they overshadow any low volume you may want to use. the output power was less than My old GeminiGPA 3000. As a pro audio guy for over 40 years the manufacturers have lost their way. The only time this amp could be used is in a dedicated amp room away from the main music source, not sure if the one i had was faulty but the output power was extremely low. Save yourself time and trouble avoid this.
