Hidiamond vs Hifidelity interconnects

I don't understand your question.

Cables are very subjective. If you read through the 2 latest threads on these 2 brands, both mention the other and there is a lot of comparing and contrasting.

For my system, I found the High Fidelity speaker cables and rca's work the best (highest level) whereas the balanced Hi Diamond and power cords work the best (also highest level). I get better sound out of the High Fidelity rca's than the Hi Diamond 3 XLRs. The difference is greatest at the highest level in my system - its not even close. Characteristics such as speed, openness, clarity, micro and macro details and a "you are there" palpability are important to me and that is where the High Fidelity's excel. Just my opinion.

Any perceived thinness in bass for the HF cables is due to not enough breakin of the cables. the musicality is there in spades, as is the bass, once the cables are properly broken in. It DOES TAKE PATIENCE.

I am inpatient as the next guy, but stuck with it for several hundred hours. My HF cables have really opened up and far surpass what the HD ics and speaker cables were able to bring to my system. The cables are much better than I expected them to be.

One cautionary note - the HF cables are not "tuning devices" - they will very organically reflect your components and bring out their capability better than any other cables I have tried, including HD.

As far as I know, nothing has changed. Rick has added 3 models of further refinement and performance beyond the original CT-1(Enhanced, Ultimate and Ultimate Reference). In addition, as people are finally starting to listen to Rick and break them in for the duration he recommends, they are achieving much higher performance levels than when they originally put the cables into their systems.

There may or may not have been small running changes over the past several years as production evolved with the highest performance cables, but those would have been barely noticeable, if at all.

If you are talking about his earlier beta test cables, then yes, they have changed considerably for the better since then. That is the purpose of beta testing. Hope this helps.
