Help needed! (Magico S3 or TAD Evolution One?)

[Floyd67]

I've been looking for new speakers and have been in contact with two sellers lately. The first seller is offering me to buy a pair of Magicos S3s, and the second a pair of TAD Evolution Ones. They are both great speakers, sold second hand in great condition and similarly priced when sold as new. However, the TADs are about one third cheaper than the S3s but my current speakers are the Magico S1s and I have been super happy with them. Both speakers are also SAM:ed.

The main reason for my upgrade would be to of course gain more bass, a more physical sound with greater air pressure and an even greater sense of presence in the music.

Which one of these great speakers would you choose and why? Please help me, I can't make up my mind... 

Have you thought about adding two sub-woofers to give you the extra bass extension? It could be worth doing a comparison first, save you plenty and give you even more enjoyment.
