Yes, you can run out with only 10 outlets, by my count I would need at least 14. With one of these you could control the frequency of current going to your TD-124 and keep it nice and steady at 33.4 rpm. I wonder if my 40 year old outlets would suffice for one or would I need a complete re-wire to make something like this financially viable. Great products.

Another reason late-night listening sounds better than daytime listening is that our hearing is sharper at night--we hear more texture, color, and detail. Evolution (or a higher power, depending on your point of view) has equipped us with hearing that that becomes more sensitive during hours of darkness, peaking at about 3:00 in the morning.

I used to have a PS Audio Power Plant ('Premier,' I think). I loved what it did for my DAC, but it broke down constantly and I got tired of taking it in to be fixed, so one day I left it out with the trash.

It may also be due to something to do with the different kinds of 'electromagnetic' radiation the Sun emits during the day light hours ........ Some are invisible and can penetrate everything .......... During the night time they are markedly reduced and/or not there ..........

Wonder how audio systems would sound inside NORAD mountain complex? :-) ............

May be a 'higher power' is affecting our hearing :-) ..............

I don't agree with the 'level playing field' argument. An important quality in an audio component is it's rejection of mains noise. A really good amp should not be affected by mains quality at all, or at least as little as possible. By ignoring this important property your reviews will be less relevant for real world audiophiles, not more.
Anyway, for most of us the question is not how much difference it makes, but how much difference compared to investing the same amount of money in your system.

It seems each company with the release of each new product tries to out due their competitors previous obscene price for a similar product. I fear there will be no end!

Anyway, I've yet to find any power conditioner, no matter how big/fancy, that did nothing but damage to the sound of any amp that it was feeding. Less demanding source gear, well that's a different ball of wax and there are plenty of gains to be discovered there by using power cleansing devices.

There is obviously a trade-off involved with these products. One must choose having protection or unrestrained dynamics/power. You cant have both! Spending $10K on a product that touts the ability to run one's whole system without compromise seems damn silly to me. Its like shooting yourself in the foot

Amps Goto Wall Directly
Source Components Goto Power Conditioners
