Different sort of noise

[Pharos]

I am amazed at some of the noises I get from things, particularly my PC; as I turn my head I get odd harmonics from what can only be its fan or HD.

I have a very low tolerance for extraneous noise, when I am trying to listen to music. Transformer hum, mechanism noise, fans, all ruin it. I have got rid of equipment because of it: Esoteric P3 ridiculous amount of noise while spinning a CD/SACD, T&A V10 fan noise, and all my computers are as far away from the listening chair as I can get them, including HDs behind racks etc. I suspect the Sony HAP Z1 will also go soon, as its a noisy sod at times.

I do have two Dacs that suffer from transformer hum sometimes and I am hoping a DC blocker will solve that.
