Personally I don’t trust Onkyo or Pioneer now that they are associated with Onkyo, especially for Refurbished AVR.
As I’ve said before, I don’t buy refurbished. But if I were to, I would buy a brand that I feel has the best reliability history.
Like if I were to buy a used car, it would be a Lexus since Lexus has the best reliability history.
I am confident the Yamaha A2070 series will be great with any speakers.
I think it’s ridiculous to think that B&W would pair better with Pioneer AVR than any other brands.
I used to own the B&W 802D2 and Revel Salon2.
