Marantz SA-KI Ruby vs Denon DCS-A110 Anniversary Edition

Thanks for the replies everyone. While I am not unhappy with the sound coming from my Marantz CD 6007 I can't help but to admire the build quality of the KI Ruby and the Denon. I would think there would be a big improvement in sound as well. I am a cost conscious shopper and have been looking at the used market as well as b-stock/refurbished.

I would seriously consider the Marantz 30n sacd as well but seeing the Ruby may still be had around the same price it's  great options to have . I ended up with the 30n sacd when choosing at this price point  and couldn't be happier!

I haven't compared the 2, but will say, you can't go wrong with the Ruby, I love mine.  I kind of wish it had xlr outputs like it's big brother the Marantz SA10, but it wasn't a deal breaker, especially at the cost. 

Marantz SA-10 replaced my Esoteric K-01. Never looked back. SA-10 is that good sonically, well worth the money. I use XLR outs. settings, Dither 1, Noiseshaping 3-1, headphone amp off, Gain set to low (does make a difference for some reason, mid is OK, but low is more details). Sound s best ofter being on and in use for a few hours. 

Can’t offer anything about the Denon, but FWIW very happy with the Ruby. Tremendous improvement over the Oppo 105, and functions as a very good DAC for me.
