HiDiamond Power cords...

Kzhtoo,
I use a 3XLR interconnect and the D8 speaker cables along with a P3 and P4 power cords. I have not heard what the XLR2 or D5 speaker cables or D9 interconnects sounds like so I have no real idea what upgrade would be best?
I'm guessing either the D8 speaker cables or another P4 power cord. You could try the P4 on different equipment to determine the best location for it.
Just a thought, it's all good :-)

My thoughts - upgrade to P4 wherever you can. This provides the foundation for the HiDiamond sound. I realized that the full potential of all their other cables was only really revealed with that P4 foundation. I now have 7 P4's, one to each component, and 2 20A IEC P4's for my 2 Running Springs conditioners. On the Running Springs conditioners, the P4's blew away the vaunted HiZoot Running Springs cords.

Kzhtoo, while I totally agree that power (cords) makes the biggest impact - always put the best one between the wall and the power conditioner - I would advice in your case to upgrade the HD dig ref to, e.g. High Fidelity Cable CT1E or CT1U digital (note HFC only has RCA jacks) as you can amplify only what comes from the source. I have had the HD dig ref but the HFC is in a different league for digital signal transmission.
The HD D8 SC is wonderful and as you can see in my system, displaced the HFC CT1E SC.

Can someone inform me if the 3m HD P4 sounds better than the 2m version?

Thank you guys for the reply. Another P4 is on the way, I'm thinking it'd go to the pre-amp. I will also try it on the DAC or amp as well. But my system is 2-channel/HT and pre-amp is where everything meet, including the sub (I use RCA output for sub and XLR to the amp).

If it is on the DAC, it might only improve 2-channel. I'm also intrigued with the kind of improvement I'd see if it is on the amp. Any thoughts? Could be a good learning experience trying P4 on each equipment.

I now agree with you guys that P4 is at whole another level than P3. With all the effort and money spent for the last 2 years putting together this system, it seems P4 is the door to the real high fidelity sound. All the equipment seemed to be hindered previously and P4 is that last missing piece. My first P4 is now from the wall to the power regenerator. Without me mentioning anything, my gf asked if I bought new equipment because it sounds so much better now. (BTW, even my TV brings out the pictures better. This is the comment from family and friends).

Kzhtoo, I would start with the P4 on the amp as it's gauge should be better for your amplification. I am awaiting my P4 20 amp to have the 15 amp connector put back on as I had sold my EAD Powermaster 2000(20amp) and now use a Hybrid tube Integrated(15amp). The P3 that was on it will move to my CEC belt drive player. As to the P4, it is a different league than a P3 for sure. I have 3 in my system and I've said in recent posts, my merry-go-round has stopped here......unless HD finds another realm that we aren't aware of.......Happy Listening....
