After installing the GroverHuffman Pharoah A/C cables in my CD transport, DAC, pre-amp and amps, digital often (7000 CDs) sound as good or better than analog, of the same recording (28,000 LPs). As a beta tester and previously using GroverHuffman Empress A/C cables (less than SOTA resolution, frequency extension and open sounding but very nice, balanced sounding), I have found the Pharoah cables superior to many $3000-$15,000 A/C "SOTA" marketed cables by companies such as High Fidelity, Transparent, Kimber, Audiosource, etc. at a cost of less than $1000. Head to head, the Pharoah is preferred (at audio shows where the dealer's are anxious to keep the cables in their systems for the show duration-however, as hand made cables, Mr. Huffman can only manufacture a limited number per day). I agree with a prior post indicating that one should first upgrade their power outlet to see if their system can reveal the benefit of a more costly A/C cable.
