minix with iptv

I have the dreamlink T1 and I find it too handcuffed for putting apps on. If I have too many apptoid market apps on they seem to lag and run terribly.
I like the IPTV in the dreamlink setup but I also run another one with a regular android app.
I had the x8 plus but returned because I was told it was not best for IPTV.
I was also told that the neo has horrible sound. Is this true. If it's not true I think this box will be the one I buy and trade in the dreamlink.
Please anyone help.
