Critical Mass Maxxum Install

And has there been any comparison between plugging them directly into wall and into P20?

Not exactly. I used to have each amp on its own separate 25 amp circuit with a smaller PS Audio regenerator. For some unfathomable reason, when I added the MSB, that configuration caused a very bad ground loop / hum. Once I plugged everything into the P20 and gave them a common ground, the hum disappeared. By the way with two REL subs, two mono blocks and the MSB, the P20 is only at 60% capacity. It works very well.

Over the years I've spent a lot of time and money on equipment in the search for audio bliss. I have spent little of either on racks. That all changed today. Mike and Rick from Suncoast Audio stopped by to help me set up Critical Mass's Maxxum rack and amp stands with my electronics. The first thing you notice is the build quality and finish on these items are off the charts (See pics below). When they said the color was Ferrari black they weren't kidding. Even if there wasn't any audible improvement in my system I would have been totally satisfied with the purchase because they hold their own with some very well built gear.

I warmed everything up for a half hour and sat down with my favorite Chesky and Mapleshade tracks to have a listen. First track, first minute - the difference was very much like a major power conditioning upgrade. When the background noise decreases every image becomes more defined and three dimensional. This was not a subtle improvement with Maxxum - it was immediately noticeable and very satisfying. True, the Select 2 and my D'Ag's did the heavy lifting but this rack by some inexplicable physics was making the presentation even more lifelike. In orchestral pieces each voice in the hall was more noticeable. Piano and percussion instruments had more percussive leading edges. Drums farther back in the soundstage popped more than with my older plebeian rack.

it's been my experience that the effect of any upgrade be it cable, speaker or front end is more pronounced as the caliber of your supporting equipment improves. This must have been the case here. I was gobsmacked by the MSB DAC when I added it. This Rackimus Maxummus has taken the whole experience to an even higher level. Thanks to Mike and Rick at Suncoast for the usual excellent customer service. My wallet is a lot lighter but it was definitely worth it.
