Mating power cords with APL 3910

While waiting for my (Denon) APL 3910 to arrive, I need some help in coming up with a short list of power cords to audition with it. In addition to listing the PCs you liked best with this unit, it would be most helpful if you could provide some specificity. In particular, what sonic and musical virtues are the offspring when the particular PC is mated with the APL 3910? Sonically speaking, which PCs didn't do as well with it? Are there any PCs that mate well (or don't mate well) with digital sources in general?

Kana813: Parallel line filters, when properly designed, can offer a pretty amazing amount of noise suppression / absorption. As such, i'm not discounting that they can provide a measurable amount of crosstalk rejection. Having said that, i'm just not sure of the quantity or consistency across the frequency range that this design can achieve. That's why i'm looking forward to seeing some real spec's from Shunyata.

Dear Sean:

Can I implement a parallel line filter at the duplex receptacle before the power conditioner? If so, how would you do this?

Dear Yada : )

If you've got an open outlet with enough room to plug in a "wall wart" sized device, simply pick up an Audioprism Quiet Line and do that. If you have an open outlet but don't have the space for the "wall wart" sized device, try using an Enacomm AC line filter. This is a two pronged power plug with a very short length of power cord wired inside of a small metal can that houses a parallel line filter. I've not compared the efficiency / absorption ratios of these two devices, but i do know that they definitely lower the noise floor of the AC branch that they are plugged into. I suggested the Audioprism first over the Enacomm as they are both easier to find and far less costly. Sean

I will buy both and see what works best. I am also checking with my electrician for an isolation transformer setup like the one you mentioned in another important post.

Thank you Sean!

Yada: Your electrician is probably going to be clueless in this regards. It will be up to you and the amount of research that you do on the subject as to who well your electrical system works. Most electricians only understand voltage & current demands, suitable gauges of wire, safety factors / legalities and getting the circuit from point A to point B. Unless you are lucky enough to have an electrician that is both an avid audiophile and reader of forums like these, you'll need to do your own looking, checking and designing. As such, look at some of the pic's and info available in the archives here and start taking notes. Sean
