Question Yamaha RXV685 vs RXA680

I'm looking to replace my Yamaha RXV681 which has developed a fault and is out of warranty. I want to stick with Yamaha as I also have some MusicCast speakers that I use in another room.

I have been looking at the current equivalent AV receiver model which is the RXV685 (£399 from Richer Sounds) but also considering the entry level model in the Aventage range which is the RXA680 (£499 from Richer Sounds).

Any thoughts as to how the two models compare?

I am aware that the RXA680 has a lower power output (80 watts per channel as opposed to 90 for the RXV685), but the assistant I spoke to in Richer Sounds yesterday seemed to think the RXA680 would be better for playing music. I use the AV receiver for playing music as well as for watching TV/movies. I'm not bothered that the RXA680 has only 4 HDMI inputs and only 1 HDMI output as that's all I use. I'm also not bothered that the RXA680 has lesser Zone2/Zone B functionality for outputting to wired speakers in another room as that's not a feature I've ever used.

My main concern is how the two models will sound, including when used for music playback. My speakers are a set of KEF KHT2005.3's which are still going strong after a number of years of use.

Buy the RXV685. You'd only really be getting the Adventage build if opting for the A680.

So you don’t think the A680 would sound better? Would I need to go for an Aventage model higher up the range to get an advantage?

I think it would sound much the same as the V685. The lower tier Adventage models don't use a different DAC and their components are basically no different to those used in the RXV models. The only main difference is their casing/chassis and the addition of the "wedge" fifth foot which is supposed to reduce resonance. It isn't until you get to at least the RXA1080 that you'd be gaining anything by opting for an Adventage model over the RXV models. The only other reason to go for an Adventage model is if wanting pre outs and the lowest model Yamaha do with pre outs is the RXA880. This is in effect what would have been the RXV785 if you'd have left the fifth foot off it.

What about if the price is same at the moment for both?
At Richer Sounds both priced at £439 should i take RXA680?
Dante what you recon?

You'd be gaining in terms of build quality if opting for one of the Adventage models. They have a better chassis design than the RXV models. What you'd not get are the 2 HDMI outputs, the phono stage or the front left and right pre out associated with the RXV685.

@dante01 please i have read most of your comments but still note sure about the following:

- is there a really clear sound difference between the V685 and the A1080 ? they don't use the same DAC i know but on the field and using mainly low volumes and small speaker packages....

what do you think ?

You;d ideally want good quality speakers to reap the benefits of the differences. The power supply is better and gives cleaner power and the DACs onboard the A1080 also impart less noise than the Burr Brown DACs employed onboard the models below the the top three Yamaha models. There are improvements and you will perceive them, but do not expect night vs day like differences.
