I have my first HD tuner built into my AV8003. I hate to comment much because I haven't sat down to figure out how to go back and forth between the analog and digital version if possible, I'd think it would be. I haven't listened a great deal either. I put it on sometimes in the background while on the computer. My initial impression is the HD is better due to the lack of noise. Sometimes though I wonder if it wasn't for the noise if it would actually be better. It's like getting a remastered CD, it almost always is quieter but sometimes it just has an artificial or not as natural sound. I often wonder if my impression is such because I've grown accustom to the original sound or if the "artificial" character is really there.

Believe it or not some of Kenwood's tuners are excellent and real giant killers. The trick is finding out which models are like that and which were just made for rack systems or entry level. I had a KT-3300 that was one of their best, if not the best they built. It was an FM only. I compared it to an Arcam tuner one time, the Arcam was not better on sound quality, they were actually pretty close, but the Kenwood killed the Arcam in reception. Just using the same antenna connection from one to the other the Kenwood pulled in at least twice as many stations. The KT-3300 was built in the late 80's, it was a digital tuner that featured an analog knob in addition to the seek/scan. It was a cool tuner. I sold it though to make room in my rack and i don't listen to FM if I get a chance to sit between the speakers.
