Just tell them my story. I had a home theater based system with an S300 power amp supplying JBL 590 speakers. Streaming from Apple Music from Apple TV. Great for convenience and flexibility. I thought it sounded okay.
Then I got Revel Performa3 speakers for L/R. So much better.
But then, my dealer loaned me a NAD 368 because it has potential to add Blu streamer module and HDMI for 2 Chanel TV. Well holy holy holy Mary and Joseph. Listening to MQA on Tidel is a revelation. I had a friend check me. He heard two songs and said the NAD playing Tidel way better than the AVR playing Apple Music. And he told me has bad hearing.
Once you know, you know!
Good luck and have fun.
