Removing power conditioner...

The power cable feeding the power conditioner is absolutely critical and often the weak link of any conditioning system. Many cables just can't keep-up. I've experienced this multiple times.

On the other hand, an excellent power cable on a great conditioner or well-constructed power strip can benefit the entire system.

I use a Furutech e-TP80 with good results.

Or as suggested make your own using better outlets. However use an IEC so you can use your own high quality PC.

For Roscoeiii: the Furman REF20i has all the video, and the amp, a Bryston 4B-SST2
The PS Audio P600 has the digital stuff, A Behringer DEQ24966, Adcom AD700, Sony SCD777ES, Sony SCD555ES Sony SCD333ES and set to 90hz output frequency instead of the usual 60hz.
The PS Audio PPP set to 'Multiwave' has the Tube Buffer, A VAC Standard tube preamp (sort of big for a buffer to ameliorate the digital grunge, but it works well) the Bryston BP-26 preamp, An Audio Research Sp-15 I use just for it's tube phono section on my second TT. The SinglePower MPX3 tube headphone amp a Lil'Dot III headphone amp
(I just tried the Adcom DAC on the Furman, as it did not sound as good running at the 90hz.. So i do try different stuff here andd there..)
I like keeping the load on the two PS Audio low, then they do not get too hot while running. Both PS Audio regenerators run very cool as it is now.

At the level of involvement you have in your system, adding more dedicated circuits would likely be a relatively minor cost, comparatively, even if you had to change panels. John
