power conditioning question gentlemen

Can you measure the voltage and THD of incoming current that you are getting? And the turntable speed.
Power conditioning can be a complicated thing, you might have to experiment a lot. My case was simple - I had fluctuating voltage and dirty current in the apartment. Until very recently I was using inexpensive Furman voltage stabilizer/conditioner. It didn't stabilize well, cleaned up the current a little but not well. Now I have PS Audio Power Plant Premier regenerator and the difference is huge. But your situation is different, and those two subs require an additional thought.
I would probably first try something with the turntable and phono only and then go from there. You could start with PS Audio Dectet conditioner from Music Direct for $400 that can be easily returned.

My PS Audio unit shows me that in most cases incoming current has over 2 % THD and outcoming 0.4 %, that's a big difference that I can hear. 117volts should be alright for most equipment but some will sound better with 120V-121V. You could get the same unit, it shows up on Audiogon from time to time, the going price is $750-$800, and plug in your turntable, phono, cd transport and dac. Not certain about your amp and subs, that could be too much for the regenerator especially for subs, I guess. Just an idea.

Oleschool, this is wild hypothesis of mine. What if in fact you want better amps and better subs, something that would give you all the reserves and peaks of power and then some? 'Unlimited' power taking any shape and form you want it to. No power conditioner in the world can be a substitute for a great amp. And great woofers, subwoofers.

I meant nothing disrespectful, I only tried to guess what you really might want, that's all. And I in fact stopped posting here because it appears that there is nothing more that I could add.
In the beginning I did say that wrestling with electricity could be complicated, few of us get it right quickly, just like cables it often takes time and effort and often is not inexpensive.
