HD Radio vs Analog FM

I recently discovered an amazing NPR radio station (music) out of Santa Monica, CA called KCRW. I listen to a relay of their signal in Santa Barbara at 88.7 using my analog Magnum Dynalab 102 tuner. It sounds pretty good but the signal is not the strongest, I have heard this tuner sound like CD quality with other more powerful stations. I also use a Magnum Dynalab indoor antenna.

I noticed that the station I am interested in also broadcasts in HD radio. Can anyone tell me if the signal on the HD frequency will be of equal broadcast quality to that of the analog FM signal. I do not know much about HD radio. It seems that most people listen to internet radio. I prefer to listen to radio the old fashion way, over the airwaves (nostalgic I guess).

I found out that DaySequerra is one of the few HD radio tuner manufacturers around. They have a new unit coming out in Q4 called M4-HD. I may look at once I find out more about HD radio.

With this radio station and my TIDAL streaming account I am very excited by these new sources of music for me.
