Mixing and matching components has been a great source of enjoyment for audiophiles since the early days of Hi-Fi.
With the advent of really well designed digital audio receivers, I2S bus implementations, DSP and great DACs, products have emerged that provide amazing performance with remarkable simplicity.
For this we suggest you take a look at the miniDSP SHD. The SHD provides all of the above plus opens the world of proper subwoofer integration and Dirac live to the mix
My SACD Transport feeds so much better signal to my DAC compared with streaming end...
I mostly use Roon to stream my 2000+ album digital collection with Bluesound Node + Ideon 3R Master Time reclocker + Ideon Ayazi MKII DAC. Recently I got a used PS Audio PerfectWave SACD Transport to rediscover my CD collection from years ago that my parents brought back to me from their home, which I have not touched for a very long time. I thought the 3R reclocker would clean up much of the signal from the Bluesound to the extent that streaming will not sound much worse than CD -- Indeed, I have been satisfied with its performance. I was wrong. The CD playback experience totally blew me away. Much darker background, much better soundstage and depth, lots of details, and better dynamics with great authority... I guess you really need a good streamer to catch disc playback! At any rate, I plan to upgrade my front end to one that works with the SACD Transport's I2S output so that I can enjoy my SACDs as well...
