Guido, the reason I asked is because, as I thought, you are switching more than one cord at a time. From my experiences, the power cord on the source makes more of a difference than the cord on the amp. So while you say that you do not care for the PAD Anniversary on the 312, what the case may really be is that you do not care for the PAD Anniversary OFF of the X-01. To truely test the PAD Anniversary, you should borrow another one and leave the first PAD Anniversary on the X-01. Otherwise, how do you know the faults that you hear with the PAD Anniversary on the 312 are not actually the faults of the Anaconda on the X-01?
The PAD Anniversary may yet be the 'star performer' as you speculated, however, if you move it downstream and replace it on the source with a lesser cord, I would say that your complaints are about the Anaconda on the X-01, not the Anniversary on the 312. Just my $0.02.
Cheers,
John
