After several searches in specialist forums I found out among other things that the 2M Blue could be a significant improvement, because the needle has a higher quality diamond, the "naked" and not just "typed" as in the Red.
In addition, it also turned out that you can, as long as you the 2M Red cartridge already has, the Red Needle can easily replace it with a 2M Blue needle without having to buy the entire pickup / exchange, not only 50, - Euro more than the needle costs, but especially the effort would involve a complete readjustment to be!
Said, ordered :) .. after the new needle was recorded (approximately 40 - 50 hours), verily a clearer sound improvement unfolded against the Red with a friend I conducted some blind tests with different types of music that the clearly confirmed repeatedly. , This auditory comparison is precisely why good and fast feasible, since you always have to replace only the needle briefly.
Advantages of the Blue against the Red in the Summary
- Wider frequency response
- Better spatial resolution
- Higher quality diamond, the treble, mid and bass finer and more accurate maps
Conclusion: the upgrade is definitely worth! Especially since you no longer have to spend the long term, because although the needle of 2M Blue costs twice, but also lasts twice longer than the 2M Red (according to the homepage Ortofon: Red 1000 hours / 2000 hours Blue)
Addendum: only the needles of the Ortofon 2M Red / Blue are loud Ortofon interference interchangeable; The same is true for the needles of the bronze / Black. So if anyone think about it in a Red Sox / Blue or pickup a Bronze / Black needle stuck: mechanically possible but technically not recommended. If you have questions simply use the comment function.
