I believe that is the name of the company. The owners manual will give you the info you need.
I had a couple Carver amps back in the day. Pretty good for 35 yrs ago and decent prices. The A 21+ is on the warm side sound wise like the Carver.
Will there be a dramatic difference?
I currently am running my Thiel CS 7 speakers on a 25 year old Carver amp I have an amazing Audible Illusions modulus phono preamp. It all sounds pretty incredible. I am considering Parasound a 21 and I’m wondering if that upgrade will make a dramatic difference in the way my system sounds overall? Would it definitely be worth the investment?
