I hope some of you will help me understand Phase Tuning. From first impressions, it appears it could be nice fine-tuning tool, but I have no idea why, or if this is specific to my power.
Even after 600 hours burnin, I had difficulty getting the spaciousness, texture and micro detail I wanted from the P5. I did finally get to a really good place, but with so many people finding power plants more plug and play, I kept wondering about wildcards like Phase Tuning. Compared to minimal conditioning before (an Uberbuss and modded Brickwall), the P5 was a breakthrough for voltage regulation, but had for me (all slight) a darkish density, hardish edges, and related micro detail limitations. I craved subtle qualities more complex micro detail can offer.
Having heard phase is a rare issue, and if all the meters display logical info…don’t mess with it, I looked more at cables, feet, room circuit noise cleaners etc. The biggest breakthrough toward more micro information was a DIY 8 gauge cable with many twisted silver on copper teflon wires of various gauges and rhodium ends. The thought again…had this done something good to the Phase.
Another breakthrough was using a Shunyata Defender for a filter in my modded Brickwall and running the tweaked Mac Mini, Tranquility DAC, and linear USB power supply through it, the Brickwall plugged into the same Furutech receptacle as the P5. Through the P5 at this point, the Tranquility is really good, but comparatively, it loses a little too much space reference, harmonics, complexity… Added up, for me, this can make the difference between very, very good sound, and a natural sense of real players in space.
Finally, with the most lively feet I have under the P5 (Synergistic Research MIGs), it was sounding really amazing with my Decware Amp and pre into the P5 and the front end into the Brickwall with Defender.
From this happy zone, with excellent stable power and sound, I have been playing a little with Phase Tuning. In this system/room, set at minus 3-4, I get a more spacious sound that is articulate, but also smooth, complex and textured, and with a nice musical warmth. One of things I work toward is resolving clear differentiation between notes and ambient trails near and far…smooth and natural transitions, the edges made sweet by complexity and spacial ambience that just goes and goes.
At the moment, the P5 meter reads 122.1V in and with it set at 119V, with the Phase at zero, the output voltage says 119.8. With the phase set at minus 4, the output voltage says 119.6V. THD in is 2.5-2.6 and out is .1 both ways.
Can anyone help me to understand this phase thing? Is there a good reason for what I am hearing? Is Phase perhaps an important tool for subtle adjustment? Is the Phase here in my house a reason for some of the difficulty I had getting the sound I needed from the P5? Or any other thoughts?
