MY FIRST POWER CONDITIONER PC

My first RMAF was this year. It was great! Everyone should go and experience it. I'll be back next year. One thing that stood out is the EVERYONE was using a power conditioner. I know the hotel's electric was polluted but it got me thinking that I might benefit.

I'm running a Peachtree decco 65 watt class D amp to Zu Essence speakers. Source is my Mac running through Amarra software. A friend suggested Shunyata. I've also read the marketing literature on the PS Audio "regenerator" power supplies which sounds interesting. I'm open to any brand and I prefer to buy used. I'm prepared to spend $1,000 or so if necessary but I'd like to get by on less. I have a dedicated circuit from the fuse panel which happens to be less than 12 below me and only runs two hifi pieces, both very light draws: the Peachtree integrated and a DAC. My questions are:

1. Is an old PC is a good start or have they have made big strides recently so that a new one - even if a lesser model - is better. There are some older models at much lower prices. How old is too old to be a good value? Should I look for something within X number of years old?

2. For my initial purchase, how should I split my budget between the PC and the power cord? I have a "HSR-1 by TG" power cord that was recommended for a previous amp, a Parasound JC1. I also have a ZU Birth power cord. Should I start over or use one of those for now?

Thanks in advance for ideas, suggestions and comments.
