Maybe looking at the following to replace my Magico S-5 MK 1

I have heard 3 or 4 different Magico speakers and do not care for them at all.

Thanks, but was not looking for opinions on my Magicos.  I was asking about the three speakers posted above.  I know what my Magicos can do, well and not so well.

Stereo5 what speaker do you have???

Of the three you have listed, I have heard all three although NOT nearly within an acceptable time period. Different audio shows. Among them, I prefer the Martens. I value reasonably full range without brightness. It all depends though on your preferences and existing equipment. The Martens can sound pretty magical and are not a tough load for an amplifier. With that being said, its your money. If it were my money, and it was recently, none of those were (or would have been) on my short list including the Magicos. Horses for courses though. Good luck in the search.
