Denon AVR X3700 vs Marantz SR5015

Even if those units are new , It won’t take much time , that there will
be other receivers with newer audio formats ( Auro 3D v2 , DTS X pro )  , etc .
You may be  tempted to change for the new flaver of the month.
If it is your style, buy a brand that is easy to sell .

But why buying those receivers if you do not go the ´´ height speakers ´´ game : Dolby Atmos , DTS X , Auro 3D .
You pay for things you will not use.

If you only go the 5.1 speakers layout ,  think about  Denon AVR-S650H  or a  Yamaha RX-V385  etc .

I see your point. And i did start to think about the “height“ speakers. I’ll look into those you mentioned. Thanks

Worked for Magnolia for a bit and got to compare all their AVRs using B&W 804 D3s. If you’re looking for neutral and the most transparent sound I’d recommend Yamaha, and if you find your speakers a little bright or would like to add some tonal richness go with Marantz. Either way, by all means find your way to Accessories4less.com and save a bundle — both the Yammy RX-A880 and Marantz 5014 are available for $799 with free shipping. IME Yamaha has proven to be the most reliable of all the mid-fi brands if that’s a concern. The Anthem MRX520 would be a significant step up from both (if you only need 5.1) but costs $1399, which may not be worth it given your application. Hope this helps, and best of luck in your search.

I second the Anthem
