This is a good start. Here’s Tidal trying to explain simply why MP3 sounds worse than CD quality. They want $20/month the stream CD-quality to you, so they will strongly market against lossy compression.
But it is also a bit misleading because so much music is recorded in 24bit and then down sampled to CD quality. I do believe that 16/44 is officially the start of “high-resolution” these days, because MP3 lowered the bar so much.
16/44 is just the start of high-definition (it is high definition from 1980) and if people are willing to pay $20/month to stream it, I’m all for it. If they ever add a radio to the PonoPlayer I would stream 16/44.
The Tidal proposition – $120/year for random-generated CD-quality music. That’s what you’d pay for 7-10 HD album downloads, not a bad deal.
