Hi all- I'm new to separates. I had to return my Onkyo Tx RZ3100 because of dreaded SP wire issue that kept shutting off the system. I also had the 4k video issues everyone talks about online. These are common problem thus I decided to avoid another Onkyo, although I will add it sounded very good.\n\nI was only able to get in-store credit thus I had to decide which route to go. I went in looking to buy the Marantz SR 8012 receiver but the salesman got me thinking about upgrading to separates.\nI decided on the AV7705 but then then needed to make a decision on an amp. I was looking to buy Dali Opticon speakers at some point but I now realize they are 4 ohm speakers and the Marantz 8077 does not power 4 ohm. I was able to get each Marantz at $1800. Admittedly, above my budget. (you only live once).\n\nI was told this amp will sound better than other more powerful amps. I mentioned to him Monoprice and Emotiva as possible alternatives. \nI'm now not sure what to do with the amp and thought I'd ask here. Do i return it? Replace it with what? IS there a better cost option I should consider? And, will I notice a difference?\nI only have a 5.1 system right now but will eventually move to a 7 speaker system once I've purchased new fronts\/center. \n\nI'm interested in everyone's opinion on this system. I suppose I could look into different speakers but thought I'd ask the group.
