Power Conditioner recommendations?


I presently have a very old power conditioner. I would like to upgrade and would appreciate any recommendations. My knowledge is limited so I prefer to purchase electronics new and I'd like to spend less than $300.00 if possible. My system is pretty basic: Yamaha N803 receiver, Yamaha CD, Vandersteen speakers, I stream Spotify.  I'm still trying to tweak without getting too expensive. Thanks for any help.  Doug

Another recommendation of Furman products. I have a PST-6 in my office and an Elite 15i 7-outlet unit in my living room. The 15i has a readout of the voltage it's supplying and I've never seen it more than two volts off 120.

This product caught me eye a few days ago:

And coming soon is a review of their power strip at about half the cost but coming in at around 90% of the effectiveness. 

All the best,
