These are only my initial impressions as I have had only two days to listen to these cables:
You are quite safe with the HE-560. Unlike the HE-500 and the HE-6, the HE-560 does not seem to be too fussy when it comes to cables.
I covered the full range of the spectrum, from the Copper Venom (OCC Copper) to the Silver Poison (OCC Silver) and Silver Widow (OCC litz silver) and there are much smaller differences between these wires on the HE-560 than on the HE-6.
The main differences are: the OCC copper is a little warmer with more depth and bigger (slightly ripe) bass impact; the OCC silver is slightly lighter with more details, with wider sound-stage and tighter bass with slightly less impact. The Voicing of the HE-560 does not change much. No problems with sibilance in all cases. One issue: I was not able to completely remove a slight hardness or stridency (especially in the top range of female voice) with all cables, though I have tried only three amps so far (Vioelectric V181, Bakoon HPA-21 and HeadAmp GS-X Mk2 with Oppo 105 SACD/DAC) none of them tubes. I think this is the family sound-issue that the HE-560 share with the HR-500 and HE-6. But it is a small issue that will not bother most people--I just happen to be super sensitive to that frequency range (overtones for female voices and violins)
For this quick listening session, I would say that you are quite safe to try most of Frank's cables from OCC copper to silver-clad copper to OCC standed silver and OCC litz silver. And the sound would be between the Copper Venom (warmer with more depth, slight bass bloom with more impact) on one end and the Silver Widow (more details, with wider SS and tigther bass with reduced impact) on the other. Now, these differences are small in the case of the HE-560 so I think, once again, your are quite safe no matter what you decide.
my friend..the hardness and stridency i am also very sensitive to..until now the only remedy for that i thought was a good tube amp..but i now found out also ss amps can do the trick without the mishaps most tubeamps have in their soundsignature and the things we so love in ss amps... I dont know whats ur budget..but a bakoon amp is rather expensive for most of us..so i could advice u to contact the maker of my amp (see my review) ... As the he500 and my code-x (a heavily modded he-5) dont even have a hint to harsch treble extension, the violins and especially harps or triangles sound without any ringing... As those 'vibrations' give me a headache if i listen to long to those kind of things....as my hearing is a bit to sensitive..
So..am not trying to sell u stuff..if ur in the market for a new amp..contact them..and they attend lots of audio exposes..so maybe u could attend one on which they are also..u have nothing to loose and everything to win if u want a balanced sound without that thingie...but be prepared to wait around 8months and to have at least 200hrs burn in time
Now i go back to lurking mode
Have fun guys!
