New to this, please apologize if this was asked, but I could’t find any more information on this.
I have recently acquired an ex-demo P3 for few reasons, one was to have programmed socket control and, obviously, some mains filtration. I actually have question on both…
My setup is nothing extraordinary, built and modified over years, but is quite reveiling. CEC TL51 CD player -> Unison Research Mystery One valve preamp -> Marantz MA5 monoblocks -> KEF reference 201/1 speakers. Components are DC coupled.
Due to DC coupling, I always had to power up the preamp first and give it a minute or so to settle down before powering up monoblocks to avoid a loud thump through speakers. The P3 gives an option to have a programmed / delayed power on/off of each power outlet, configurable via web interface. So I did that.
I’ve set power on to delay certain sockets by 60 seconds. All good.
Powering off requires me to power off monoblocks first, then the preamp and the rest. So I’ve set to delay preamp turn off by 10 seconds. Which works, kinda. What happens is, when I power off the P3, all sockets go off immediately and a second later they all power on again and then 10 second delay kicks in. What a mess! Any advice is highly appreciated.
Now on power regeneration. I feed everything through the P3, which takes about 130W all in. I do notice, that the system has a good deal of reduction in dynamic range, yet it sounds ok. So I tried reversing power sockets, which did make the sound top end more extended and what seems more impactful (can’t say brighter), but way too sterile or analytical somehow fatiguing ears after a while. I have a choice of other 2 passive preamps, TVC and LDR controlled, but they only slightly tweaked this and that of the spectrum, but the listening is still intense… I wonder if this is more of burn-in question or this sound signature will remain? What’s your experience?
Apologies for a rather long post, thanks in advance!
