Blue Tooth tube amps/integrated amps/home theater receivers

I have been an audiophile since 1970 (I'm 75), while overseas serving my military obligations, There I was introduced the local Military audio club.  Place where GI's could audition and purchase the likes of McIntosh, Marantz, Sansui, Dual and other components.  I built up to McIntosh and Marantz tube components.  But, I find that now adays I am listening to music on my iphone or ipod, via Bose Quiet Comfort headphones.  I don't listen to music like I used to, more of background music now.   I still have my tube mono blocks and tube preamp in their original boxes since my last move 6 years ago.  Question is:  Just how good are these hybrid blue tooth tube amps, integrated amps and HT receivers?  I googled top 10 best and this is what popped up.  Rockville blu tube 70w  amp/HT receiver.
 
Second was a Nobsound MS-100 MKII HiFi Blue tooth Hybrid amp.  Now, these are fairly inexpensive, case in point, get what you pay for?

Any other recommendations?  Thank you.
