At that price I wouldn’t buy it without an in-home demo. My experience is really good room correction can be more than worth the additional A-D-A conversion, but it can obviously vary depending on system, room, level of treatment, etc. The other option is to buy used and hopefully sell at minimal loss if it doesn’t work out. Best of luck.
