I encourage you to go tape something you don't really care about, and run:
- 1 song at XY
- 1 song at DIN
- 1 song at ORTF
etc, etc.
Then go home, and listen to those songs in the car, in the living room, on your iRiver, whatever. I expect you will walk away with opinions on what YOU find pleasing to your ears.
I spend a lot of time listening with earbuds and an H120 so I generally choose the pattern that I like in that setting. As long as it doesn't sound terrible in the house and car, I'm happy. Other people have an audiophile grade system in the living room and want to optimize the taping for that playback. There are no right or wrong answers, just opinions.
