It has been ages since I last shopped for home theater equipment and my receiver in particular is very long in the tooth (but still sounds great).
I have a 5.1 system that I purchased going on (gulp!) 18 years ago comprised of: (1) a pair of B&W CDM 1NT bookshelf speakers being used as front channels, (2) a B&W CC6 S2 center channel, (3) two B&W LS1s (small satellite type speakers) mounted on the rear side walls for surrounds and (4) a Rel Strata III subwoofer. My receiver is a Rotel RSX-965.
The system is in a small Den probably about 10' x 11' but there is a hall about 3-4 feet wide leading into it and that side of the room is almost completely open going into the living room. Front speakers are, by necessity on a wall that is about 7' long, so separation is not great. I have a Samsung plasma TV that I may upgrade to 4K at some point, but no plans to do so immediately. Anyway, I just give you all this info as general background.
My biggest issue is that due to its age, the receiver has no HDMI inputs or switching. Additionally, I have some problems getting clear dialogue at times (not sure if it is the speaker, receiver or the mixes) and the subwoofer is probably overkill size-wise for the room, although it is tucked away in the corner, so not really a problem. Honestly, everything still functions well, so despite the age and inconveniences, I could probably continue to use everything.
That said, I am thinking it is probably long overdue to replace the receiver at a minimum. I was wondering if you have suggestions for what will go well with the rest of the system and/or if you think it might make sense to upgrade anything else (I could, for example, repurpose the front speakers in another room and use it for stereo only) and buy a new speaker system.
The receivers I have been looking at, or which have been suggested to me are the Marantz Sr 6012 (which I can get at a very good price-- about the same as the new 5013 - because it is being replaced - but it seems really intended for a much larger system), the Anthem MRX 520 (downside is a lack of Dolby Atmos and DTS:X ability, should I ever decide to go that route), Cambridge Audio CXR 120 and the NAD T 758 V3. The Anthem at about $1400 is really at the top of the range price wise and I wonder whether I have to spend anywhere close to that to get a good receiver. On the other hand, I don't want to have to take a step backwards from the Rotel in sound quality.
Any thoughts, suggestions or other input on the above, and particularly with respect to receiver possibilities (including those I mentioned above) would be greatly appreciated.
Many thanks in advance.
