Many 10A cables offered for sale on ebay bear the suspicious (IMHO) marking on the jacket:
XLO ELECTRICTM REFERENCE2 TYPE 10A FIELD OPTIMIZED AC POWERLINE by XLO ELECTRIC, U.S.A. protected by U.S. PATENT NO. 5,110,999
On the genuine one are written:
XLO ELECTRICTM REFERENCE2 TYPE 10A FIELD OPTIMIZED AC POWERLINE UL 2464E E56253 MADE IN U.S.A.
1. The suspect cable has the patent number. (Actually the patent number does appear on genuine Ultra 10) and the genuine 10A does not.
2. The genuine 10A says MADE in USA whereas the suspect says by XLO ELECTRIC, USA only (nothing about MADE IN)
Recently a 10A was offered on sale on Audiogon and from the picture posted, it has the label of the suspect cable described above. However, the vendor said: “I only buy original from the factory”.
But the innards are different too. The genuine cable has two conductors each for L, N. E respectively. The supect: 3,3,1 conductors.
Enquiries to XLO were twice ignored. If these suspects were counterfeits, I would think XLO would be eager to find out. Their silence is baffling.
1. Could there be two versions of 10A and one not necessarily made in USA?
2. Is it possible that the Ultra 10 now has the 3-3-1 configuration and some counterfeiters are “copying” the Ultra 10 design and label them as Reference2 Type 10A? (Note the genuine Ultra 10 also has the Patent No. on its jacket.) Can Ultra 10 owners please enlighten?
