So, the saga continues. I got back home today and unpacked the amp to find that it has been quite badly damaged - badly enough for me not to want to even try plugging it in to see if it actually works.
Because of the huge amount of faffing about which it has taken me to get to this stage, I have written to all three parties, Audio Affair, Henley designs and Roksan, to ask that they sort this out either by replacing the amp with a new one, or by giving me a full refund for both amp and the matching CD player - they were sold as one item as the double pack.
I've asked that this is sorted by the end of the week, since I'm sick and tired of the whole thing. I'll let you know how it ends.
