Mating power cords with APL 3910

Puremusic- a cost effective way to isolate your 3910 is the ISO-21 from ESP. For "value-per-dollar" power cords check out the Supra LoRad.

I agree with Sean, that there doesn't appear to be much in the way of outlet to outlet or AC line isolation on the Hydras.

A former Hydra user with a full digital system recently upgraded to the new Audience AdaptResponse power conditioner which has 12 full isolated outlets, and says it's a hugh improvement.

Ajahu, Thanks for your input on the UO and your suggested correction for its tipped frequency spectrum.

Kana813, Thank you for your two suggestions. I'll check them out.

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
