Sorry i stand corrected, the specs are the same except for the tuner on the RX-Z1.Hope your A1 pulls through ok, it's still a great amp:emoji_thumbsup:
There are newer models out now than the DSP-AZ1 like the RX-Z9, but in New Zealand it's like $9500 which is about $6800 in US dollars.The reason i can get the DSP-AZ1 cheap is it's a floor demo model and just wanted to know if i should upgrade or not.
I currently own a DSP-A1 and i've got the opportunity to upgrade to a DSP-AZ1 really cheap, what i wanted to know has anyone done this and was it worth the upgrade? The reason i ask is because i'm also looking at a Velodyne chtr15 sub, but i'll have to put this off a little while if i buy the amp.
