Power Supplies & Performance


Howdy, folks. I’ve read in some posts here-and-there that a power supply can affect the performance of a system, and I was hoping to get some feedback from those of you ’in-the-know’.

My system equipment is below. Can any of you comment about how much, and what sort of, improvement (if any), I might have by removing the Panamax conditioner? My worry is that we have a fair number of power outages in my area, so I don’t want to place the equipment at risk. But if it’s going to make a dramatic improvement, it might be worth considering.

  • Bryston 4B-ST
  • Krell KRC-3
  • HiFiBerry DAC+ Pro
  • Panamax M4300PM
  • Martin Logan ReQuest (2nd Gen)
  • Polk PSW650 Sub
  • Cables: Acoustic Zen all around - Satori to speakers, Matrix Reference to Subwoofer, Matrix Reference XLR to amp, Matrix Reference 2 from DAC to Krell. Experimenting also with Silver Reference 1 and 2 between DAC and Krell to see what I like.
Thanks in advance!

I'm not familiar with panamax but have tried PS audio's quad running from a PS auidio wall receptacle. That was a nice improvement (increased space between instruments mostly) to the adcom (really dating myself here) conditioner. The only thing I have running through the PS audio quad right now is my sub.The rest of the system is running through an "ExactPower" transformer. You may want to research that to see if it would work for you as they come up occasionally on audiogon. The biggest improvement the exactpower made was with the digital portion of my system. Didn't hear much of a difference with vinyl. Again those improvements were mostly within the soundstage by haze reduction.  
Parabolic, try the Panamax with only your Krell and dac, while placing your Bryston and sub into wall outlets--system should sound better.

Same wall outlet, or do they have to be different?
A Bryston 4B warrants its own dedicated line of 15A or better.

I have a Panamax MR4300.  Not sure how that differs from a M4300PM. 

I know first hand the Panamax is very accurate in that it will shut down if over/under voltage is detected. Offhand I think the threshold is 130/100 respectively. 

In my case all equipment I have connected to it does not draw more than its rated capacity. But as others have pointed out, if your Bryston alone needs better than 15 amps, you may want to consider a separate solution just for that.
