I researched some, chose this one

from ProAudioStarMessage Seller

Furman P-1800 PF R

$399.00; Tax (NJ)$26.43; Shipping FREE Total $425.43USD

 I have the  Equi=Core 1800 MK2. Typical on sale @ $1395. However they make a 1200 & 600. It depends on system size and power needs.

I've been using Shunyata Hydra 8 V2 conditioner with Shunyata Venom Power cords (non high-current). Sounds good to me. Amp goes straight to wall via Venom HC cord.

n suck cheap garbage dont make anything sound betterlook for used isotek

My 2 cents -
I think your power cord budget is good for a solid performing Shunyata Venom HC v1 or v2. Great bargains used.

On the power conditioner if you can go up a little $-wise, try an Isotek EVO3 Polaris. See listing at the Music Direct link below. MD is great to deal with and have a very helpful return policy.

I would live with the Polaris and stock Isotek cord for a while, then try a Venom HC.

I purchased an open box Isotek Aquarius from MD and was surprised by the difference it made in my system (despite 3 dedicated lines). Truly like a component upgrade. Later, replacing the stock Premier power cord with a Venom HC made a significant difference for the better.

Be aware the Isotek conditioners take a C19 plug.

Good luck.
