Advice:
               1，本机音质相当忠实还原CD片或前端器材的音质，喜欢有音染及初烧爱好者慎购。
               2，请勿搭配低档信号源（如电脑声卡或低档CD机转盘）或低档的前级使用以免无法体现本机效果。
               3，请勿将机器重叠摆放，以免音质打折扣。
               4，合理匹配电源线及信号线。
               5，本机使用全铝机脚，请勿与其他器材的金属外壳直接叠放，以免产生地环路而影响音质。

My friend Don McIntosh wanted me to relay this message to you and I quote "Congratulations on the monoblocks and stereo amp, they are SENSATIONAL! The chain of Audio-gd gear in my system never sounded so great through my McIntosh XRT2K speakers! Keep up the good work. Your friend (signed) Don McIntosh."

Combo: Master 7 + Master 1 + Master 2
　

13th Aug. , Jan from Sweden:

           I have now almost completed the building of my/our "Music-room". I have waited until now to test the Master2 and -3 to drive the Quad ESL63's with the Finnish-made Sub-woofers Sw-63's.

         The reason for writing this is the fact that the Quad speakers are an easy load on amplifyers but doesn't sound good with them all.

         I can assure You that the Quad ESL-63 sounds fantastic with the Master-gear. I have allways been driven them with vacuum tube-amplifiers because of this... But with Your M-2 and -3 I cannot see any reason to return to Vacuumtubes.

Combo: Master 7 + Master 1 + Master 2 + Master 3
