HiDiamond Power cords...

I too think the key to these cables is how quiet they are. It allows you to hear deeper into the music with more information. I haven't been this enthusiastic on a cable since replacing my SR Apex SC with ASI Livelines at 4x less $$.

From the P4 description, I think the big improvement is the new plugs that will probably add several degrees of quietness.

My system has never sounded so good so will enjoy and listen for a while. I'll probably try a P4 on my DAC and maybe some ICs and SCs down the road.

I agree with the comments above.

This afternoon I added 4 HiDiamond P-4 power cords to my system, replacing a P-3 from wall to 1 amp, as well as 3 SR Hologram-As. The SR's were going from both PS Audio P-10s to my amps, which are now replaced by P-4s. The Cd player now has a P-4 from the P-10, replacing a P-3 which is now on my preamp, having replaced another Hologram-A. The 4th P-4 is from the wall to the other P-10, replacing a P-3 that was there.

Immediate results, cold, with no hours on these new p-4s: wider and deeper soundstage, lower noise level(so sounded a bit louder and more detailed) as well as deeper bass(so had to dial the sub down). We heard things on a CD that we had not heard before, literally. My system sounds better than it ever has. Its as though we went from feeding power to the system through garden hoses, to now using fire hoses with silencers. The SRs were good in my system, but the Hi Diamonds, especially the P-4s, take things up a few notches, COLD. I can only imagine when these break in... :-)

Correction- 1st p-4 replaced p-3 from wall to P-10, NOT wall to amp.

Well, I went ahead and ordered a P4. I plan on using it to power my Audience Power Conditioner.
