Dear Dr. Poon,
The M150 is the most significant new product I've had in my system in the past five years.
After only a couple of days, I can say it is markedly better than the Audio Prism line purifier in every way.

Hi
About the M150, it is a great product. My friend asked me to buy one for him from you.
After we received it, we tried to connect it to my rig.
No doubt it improves performance obviously.
A more powerful sound, a larger sound field, a more concrete singer and instruments...
Although just about 10 minutes listening, M150 shows its performance.
It is outstanding indeed.
Thank you.
Sincerely
Liu
