Sirius radio quality vs redbook cd player


Have an Arcam FMJ 27T cd player and am also streaming my cd collection saved to HD using iTunes (lossless format) to a Zardoz (modified Airport Express). I'm considering subscribing to Sirius internet radio and streaming that to my stereo system; so I'm curious about the sound quality of Sirius internet radio vs redbook cd. Anyone have an opinion?

Sat radio had such promise but its just as repetitive as the worst Iheart or Clear Channel offering and its EVERY station. Too many channels also are sucking the life out of the audio quality. Had it for a couple yrs in very start of its roll out but its not good enough to justify.
I just got a trial SiriusXM in my new Subaru Forester. Obviously not like top line Mercedes or BMW quality system-I’ve had them :) However, I’m finding the sound quality very good for car radio in this vehicle. Very happy to have the variety that’s just otherwise available in the Vancouver area of BC. I think it a no brainer for country folks : ) and May keep it if sweetie like it ; )

Man!!!! I Thought i was the only one who had issues with XM Radio.
i use it for talk radio, but then i was sent a notice saying that my monthly 
fee would go up to i think $235.00 because of artist royalty fees's and that is when i got TIDAL streaming, then i found out that not all the good music was MQA  ( JAZZ FOR ME) then i lost interest in TIDAL because i was lied to, then i found out that LG made a Cell phone with a built in DAC chip that plays MQA Model V30 AND G7 has a 32bit quad dac. i fell back in step with my music.
