Yamaha A-S801 for Dynaudio Evoke 20

Thank you Fred. Very informative! 

You’re welcome. Just a couple more observations. Minor issues. The knobs are plastic. I’d have preferred metal. On the good side it has two music modes like "pure settings" that you can kick in with the remote. Handy for fine tuning what’s playing.
I think they could have invested more money in the speaker outlets but with a light weight cable like the Ohono and banana plugs, its not an issue. One subwoofer out set at about 80hz. I just added an RCA splitter to fire the two subwoofers.
The Outlaw M8 woofs are good for $329. but you might also look at Emotivea’s 8 inch sub that is supposed to be good bang for the buck at about $300. You only really need one.
Good Luck.

Thank you! Love the info about Ohno cables. I was thinking about Nordost flat cables, which are hifi and all but expensive. 
Question about  subwoofer — why 80hz? Is there some science behind why it’s set that high? I’d expect the woofer to take over the frequencies below, say, 40hz.. or an I misunderstanding how the woofer kicks in? 

Be aware that the A-S801 speaker binding posts do not accept spade lugs.

Unfortunately, the Yamaha sub output is set at around 80 at the factory with no adjustability. The 801 doesn't have preouts so you can't use the variable crossovers in the self powered Subs. Seems to work fine for me.
I change speakers and cables fairly often so I am liking the new hollow bananas like Audience uses. Good tight contact but may not be quite as solid as spades. I don’t seem to notice degradation. Unfortunately, some manufacturers like Cambridge are forgoing spade connections.
The DAC in my Oppo 93 is going on fifteen years old in spite of sounding good. The 801 has a Coax directly in from your transport using Yamahas own DAC. Right now Im looking into whether the 801 has a better Dac than the 93. I have a Coax from the 93 digital out into the Yamaha and also the audio out on the 93 hooked into the CD input via RCA cables. Kind of cool to be able to choose sources from COAX to Analog with the remote for instant comparisons.
So I’m using a cheap Blue Jeans Digital Coax and so far the Oppo sounds better, That could be break-in, the cable or the quality of the 801 Dac vs the 93. I’m going to get some other coax cables and play with that. Yes, I’m bored.
