Finally, I managed to get a pair of TSM-MM over Audiogon!
Well, I must say I love the workmanship and the sound.
They are extremely transparent, revealing, seamless, tonally right and, most importantly of all, musical.
What a pleasure when you can breathe every detail of the music and feel it to your bone!
They are also very sensitive for recording, equipment and positioning, and I will have to do many experiments to dig out every potential of them.
Thanks so much for all your opinions, suggestions and helps! Also special thanks to Bobby of Merlin for his pro-willingness to answer all my quetions and give a hand!
I have yet to get a chance to listen to GMA Callisto however I am so much hooked by Merlin TSM now.
