Why Merlins sound better then Sonus Faber

Unistar, music is so subjective so its always impossible to say anyone component is better than another, regardless of price. Some people like the Sonus Faber sound (I being one of them). Some people love the resolution and speed of Magico, others think its too sterile. As rockadanny said, go have some fun with the money you saved!

Unistar99, that is twice now that you have asked if you are wrong. How can you be wrong when judging subjective items? Who can tell you what flavor you like best? As Rockadanny and Tboooe have noted, this hobby is very subjective, what sounds best to one rarely sounds best to another.
If you happen to enjoy the sound of the less expensive product, you are not right or wrong, you are lucky. Enjoy your good fortune.

more transparent, closer to the original recording without adding anything else

Unless you were there when the material was recorded, mixed, and mastered, and had a far better than average audio memory, or immediate access to both pairs of speakers, how would you know which is closest to the truth? Way too uncontrolled of a test to make accurate conclusions.

I don't think so at all, but may other think different as well.

Unistar99, are you a Merlin dealer?
