Qobuz or Tidal?

Looked into the Best Buy savings.
Must be a My Best Buy member, which I already am.
Appears to be half off Tidal HiFi Music ($10/mo), but it appears the reduced price is only for the first year, so it might not be worth reestablishing a new Tidal account for only one year of savings.  Certainly sounds like it would be worth it for someone just starting out with Tidal.

@mitch2 Its $99 for the first year and then $119 for renewals, which is lower than direct Tidal pricing. And you don't need to create a new account. I was already a Tidal subscriber and when it was time for renewal, I bought through BB. They send you a digital code. With this code email Tidal support and they convert your Tidal subscription to BB pricing. 

Thank you @rajivhifi
I must be paying by the month since I don’t ever remember them asking for a renewal anytime over the past  several years.
I will look into it more closely.

Thanks for the replies. Does anyone know the technical reason why one sounds different than the other? It’s a bit weird to me, are the streaming services altering the original files in any way?

@arthur1260 -- Not that I know anything, but I'd bet the honchos at Tidal, Qobuz and the other streaming companies have slightly different tastes as to what sounds good.  Putting it another way, I bet they do futz with the files. It could also be simply because they employ different streaming software/hardware. In any case, it's pretty plain the two streaming companies have different musical tastes. Viva la difference!
