Yamaha RX-V4..any experience?

Thanks. I will be using the B&W 686's for the front channels, so i guess they should be ok with the Yammy power of 80watts/ch.

@auxinput   I currently own a receiver like you describe. The main power supply is certainly quite beefy, BUT the problem is that the various caps are placed without concern as to their heat propagation, which is what I find common on a lot of this gear. As such, the failure rate is pretty high. In the old days, weight used to be a factor as to the ability, and sometimes quality, of the unit, i don't think this necessarily applies today. 
My current receiver cannot pass through 4K, which when I bought it was no issue, now it is...I like the idea of a little bit of future proofing, hence the appeal of 8k pass through.
