for the Baby Promethean Mini Isolators

I am a long time user of MD products, but haven't ordered anything in years. Recently had to send my preamp for repair and moved my Oppo 105 to my TV/video system. 105 was resting on a 3" thick John Boos cutting board. I tried several different iso devices, but none did what the springs do, not by a long shot.

I commented on another tread where someone was looking for a $1000 dac, and I recommended the 105 which is way more than a dac. One person commented that he didn't like the 105. I replied it could be his iso devices, interconnects, speaker cables...

The 105 is a heavy player. I played a wide variety of red book CDs, and was quite pleased using 4 springs near the corners, but looking for max benefit I began to move them around.

My music choice is a well recorded/ transferred red book CD: Lyle Lovett and his Large Band; cut 4- Good Intentions. Using 4 springs it has great open sound stage retrieving delicate information deep in the mix

Next, I moved 2 springs near the center of the laser spindle, then one centered. Each of the latter moves makes for a smoother sound, but a loss of slam, and sound stage depth

I then returned to 4 springs and the speed slam and sound stage depth returned

I haven't yet tried SACD, DVD-A, etc, but it can only raise the bar on how good these springs are

Product Weakness: None
Product Strengths: Adds weight, improves bass to the music. @ $13 pr a true audio bargain
