Moving up from an Oppo 205

Yes I would agree, I have experienced noticeable improvement with cables. Current a Shunyata Venom USB cable which was an upgrade from a previous Audioquest wich was an upgrade from a basic USB cable.  Also I have realized noticeable improvements with power cable upgrades.  I have all Shunyata  Alpha NR and Sigma NR on everything.  Ironically my power cable on my Oppo cost more than the Oppo cost when bought new!  But I was not a subtle improvement !

Adameos. What DAC is your 205 feeding? I have a 105D and am considering a similar move.

Before you do anything, I would recommend trying some Vibrapods under the 205's feet.  Frankly, I was never much for footers or cones, but I had some Vibrapods lying around I just thought I would try it.  IMO, the sound became much more harmonically complete and less "digital" for lack of a better word.  Just try it and you might be surprised.  Or not. 

Does anyone like the Aurender A10?
streaming , storage, and DAC all in one ?  I do like my Aurender N100. And my Oppo but my goal is again one box that does all for 2ch file playing and streaming . And gain a noticeable SQ improvement.  The Oppo will move to the TV room.....
And Yes I have Vibrapods on all components .  They do help 
thanks

Aurender A10 is a very nice all in one box solution. I am not 100% certain that you hear improvements in the DAC section over Oppo. The only way to know is to compare them in your own system.

If you already like N100, then I think you will be pleased with A10 functionality and ease of use.
