I had a very good deal recently with this Marantz amp and i m very happy with it, specially with music, which was my original goal. Now i need to upgrade my front speakers aswell. These speakers were fine with my old NAD, but now i feel that the sound needs a little more power and detail, specially with music. The movies are fine. Which speakers would go best with this Marantz? I m ver happy with BWs so im considering, maybe, the CM8. My retailer has advised me to go for the MA RX8 and the REL T7 or T9 sub, but as i was checking the monitor audio website for specs, it came to my attention that those speakers are 4ohms and maybe that's not a very smart way to go, even with the retailer saying to me that they partner the marantz and the RX8 everyday.
