Please take the following as the results in my system only and to my ears , and as with any equipment the only guaranteed way of testing it is in your system.
Without going into too much detail , i had the Couple2 on sale or return basis to compare with my Couple.
I suppose i would describe the Couple2 is a very good cable , but suprisingly the Couple is slightly but significantly [to me] better in all ares .
Why this should be i dont know , especially as i run a full Rega system. The main possibility surrgested is that the Couple2 has been developed in conjunction with the new range , whereas most of my equipment is from previous ranges.
So maybe the result could be reversed in a system comprised of the current range.
Thats why it would be interesting to get some feedback from others .
