Running Coherent's 6D speaker cables and BD jumpers, I can second Paul's findings. They comfortably trumped The TQ Ultra Blacks I was using before, which themselves beat the super-expensive Kimber Select KS-3035 I was using before that. Speaker cables have come a long way.

You've made some serious changes to your system recently Paul!

Anything on the horizon?

Are you staying 'low key' with the vinyl side of things or will that get looked at too?

Will be interesting to know your thoughts.

How many hours have you had on your new cables now Paul?

I’ve left them burning in over the last couple of days and nights and they’re opening up nicely (most of the loom is second hand, so probably doesn’t need much, if any) but the speaker cables are brand new.

What I’ve noticed is unusual. There are some recordings where I know the artist used a mobile microphone to record and it used to leave a nasty ‘cupped hand’ signature on their voice. I thought putting this loom in would make it worse (better cables show more flaws).

In fact that odd colouration has completely vanished. There are other instances where small oddities have gone; what I assumed were flaws in the recording I now think were colourations I’d grown used to.

Everything sounds cleaner and more natural, a tension to the sound has gone. Another oddity is that despite the added quietness and ease to the sound, there’s also more drive and energy to everything, bass is tighter and has more drive and the whole spectrum is more coherent.

What I’m excited about is the main plug (wall to mains) is yet to be fitted, I’m sure as this is such an important lead, it’ll have a large impact to the overall sound quality..

Nothing wrong with enthusiasm. My interconnects were new, whereas the speaker cables were used.

I certainly found the interconnect took a long time to get ‘right’, I fact, I was starting to panic when I first plugged it in, because it was harsher and less detailed than my previous cable, but within about 5 days of active use, it was a transformation. Everything opened up and became clearer and more defined, but like you found, the details there, but a lot more palatable and easier on the ear.

I plugged in my previous cable for reference, and let’s just say it lasted for less than a few beats of a song before I wanted the Coherent cable back in the system.

The speaker cable was faster, which I guess was due to it being used, but it took a bit of time.

With all my recent changes, my system has gone from being something I rarely listen to and always turned it off after a short period, to being on a lot more and me wanting to turn the volume up, rather than down.

Mirrors my experiences. I found the power cables took longer to burn-in than the speaker cables.

I have thousands of hours on them all now. Guess they're burned-in all right!

I’d say the bass weight has reduced marginally, but I believe that’s because it’s tightened up significantly and there’s less boom.

Interestingly, I always used to have to use the bungs to tune the bass but with these cables I can remove them, which increases weight, and have no ill effects like boom etc.

This is more a power cable question but I’ve just realised my power amp and of psu no longer have transformer him either - can this really be because of a cable change?

I would suggest only if the cable contained a dc blocker possibly, which our does not.

Another reason for this occurrence is probably a coincidence or another possible underlying issue has been rectified

Martin the plug was sent yesterday.

So currently are you using your original mains lead to power your isotek?
