The best digital IC, period.

I too am interested in more information on these HD cables.

Here are my initial thoughts:

I like what xyz says has been his method for comparing;
I am concerned however that there is no mention of this brand anywhere else on any audiophile forum or review I can find;
The cable is relatively inexpensive so might be worth a tryout if a little more info were forthcoming;
I too am interested in knowing what is the list of cables against which xyz's group compared

I'm currently using a Marigo Apparition unbalanced. I am about to swap in a kubala sosna emotin balanced, to compare.

I have tried blue jeans, Kimber, audioquest and a couple others I can't presently remember. The Marigo is better in my rig, to my ears, for my preference than all previous by a wide margin. Better imaging, more clarity, sweeter top end, tighter bass, fuller soudning, etc etc.

If these HD proves better than the likes of Marigo and kubala sosna, they should be able to sell a lot of cables here. But I'm unready to lay out $400 without more information.

Ps68,
I will be glad to report my experience with HiDiamond cables once I have had a chance to listen to them in my system.

I believe there are two reasons why HiDiamond has such a low profile in North America. The first is that they do not advertise. The second is that they are an Italian maker. There are many excellent foreign makers who have been unknown until they became famous. AMR from the UK was completely unknown until they recently started producing world-class components. Hegel from Norway make products that are at the top of their price-point class. Perhaps HiDiamond will become well-known as a maker of high quality cables. This remains to be seen -- and heard.

I am not associated with the group Musicxyz is involved with. I have only had a handful of cables in my system over the years, in comparison with the hundreds of cables they have auditioned. My experience will have to be taken in this context. But I did train as a concert pianist and my hearing is excellent. So this should be helpful.

Over the past 6 years I have used cables from the following companies: Mogami, Goertz, Supra, Gabriel Gold, Cardas, ASI Liveline, Bybee and Synergistic Research.

Sabai,
have you ever tried Acoustic Zen cables? I am currently trying the power cords from them and I am truly hearing a noticeable difference. These are not too "crazy" in their pricing and I am pleasantly surprised at what I am hearing.
I am buying the Liquid Cables from Teo Cables tomorrow but I think I will be picking these up as well.
I value your input as I have noticed your posts are quite thorough and informative.

Ghostinmachine,
Thank you for your kind remarks. I have not tried Acoustic Zen cables -- yet. I note your positive observations about them in your system.

I am using ASI Liveline power cords in series with Bybee Ultra and ASI Liveline power cords in series with Synergistic Research. I have found that using these cables in series is superior to using the cords individually. When the configuration is right the results are stunning. When the configuration is reversed the results are awful. Which goes to show me that cabling is a very tricky business.

Sabai, how do you connect them in series? with a special power cord adapter? Thanks.
