I'm confused on HR 24bit VS A Parasound C2 Processor at 16 bit

I have been having a struggle trying to find something better than my Parasound C2 Processor. I bought the newest Node and received it tonight. Worked great but my Parasound C2 just running with a digital Toslink out of my Sony TV smokes it in every way. I know the TV is supposed to add noise in the signal and this is a old processor and only 16/48khz . Well I hooked the Node to it totally bypassing the Parasound DSP through it's 7.1 input RCA. This bypasses DSP.  So just using Parasound volume control.  Compared to the Parasound there is no comparison and that's even with the node playing Ultra HD. My amp is a Plinius SA102 and speakers are Klipsch RF-7II. This is my third attempt in trying to better my system. I bought a Plinius CD Lad and had it upgraded with auricaps that sucked and then a Parasound P7 just to try. This sounded better than the CD Lad. But sent it back C2 smoked it too. I can't believe after trying Hi rez through a streamer the C2 keeps coming out on top by alot. I'm sending back my Node now and just going to use my TV as a streamer with my Toslink digital out into my Parasound C2. My system sounds really good but I keep reading every day about HD music and streamers and preamplifiers  that I want to believe will be a huge jump from what I have. Why does this old Parasound C2 keep coming out ahead. I know this has dual dac chips in it but really surprised that it sounded better than 24 bit. Going to Chicago to the audio show soon and hope will hear something I want to buy
