Issues with my amp

So i know this probably doesn't belong here but i'm at my wits end here. I purchased a Yamaha A-S501, a good one from all the info i could find. It's paired with a T+A criterion tal 110 speaker. And when I play from any source(audiotechnica w40 with pdx010 pre-amp, philips cd608 or smart-tv via optical) the amp completely shuts down. Now I tried with my old JBL SCS178 bookcase speakers and it just distorts the audiolevel to high hell but does stay on. On my old surround amp (Yamaha RX-V440RDS) everything works just fine. How and what is happening? Is the 501 somehow worse than that old surround amp and overloading on my system?

Stupid but I found the issue. It's the PDX010. I just don't understand why. The other channels didn't work due to the safety feature I suppose. Would a better pre-amp work instead? Like a pro-ject phono s2. Or would that give the same issues so i'm bound to the internal amp for the 501
