HiDiamond Power cords...

Sabai..thanks...i was just wondering if you did know the reason..

Calloway,

The material of the prongs are different which can give different sound characteristics. The M1/F1 is copper with a layer of platinum and palladium, and I believe the stock P3 is some sort of copper or bronze with a layer of silver. The M1/F1 housing is also made of aluminum and has additional damping which can also affect the sound.

With that said, changing to a better termination will likely result in a different sound...but not always for the better! I've always found that YMMV with your particular system. What would be interesting to see (hear) is if using plug that matches the outlet that its plugged into would lead to even better sound (i.e. using Oyaide F1/M1 or 004 with an R1 outlet, or using a gold Furutech plug with a gold Furutech outlet, etc).

@Yo2tup, I had the same thought about using the same matching string along the way...I have several power 3's going into an S.R QLS9 then into a Teslaplex SE outlet. Wondering if changing the HD connectors to Oyaides then into a R1 or better outlet would have a same characteristic improvement in the end.

Calloway,
You're welcome.

Yo2tup,
You are right -- YMMV. I have found that the best for my system are the M1 and F1. But they do not improve all cords. I tried them on a Bybee Ultra that is terminated with the 046 series and the M1/F1 did not improve the sound. Which tells me just how well-engineered the Ultra is. I have seen photos of a different Bybee PC that is in fact terminated with the M1/F1.

Yo2tup...thanks for the reply..that does make sense but, as you say, 'different sound...but not always for the better'..
