I purchased a set of MA PH3 Reference Phono cables to replace the set that came with my Music Hall mmf-7.1 table. I was getting a noticeable hum on my table and was not sure why, I triple checked all connections, tonearm wiring, earth wire...everything, drove me nuts!!! Then I focused my attention on the TT cables and knew that eventually I wanted a better set anyway, so I purchased a new set of PH3 Reference cables. I was not worried about the breakin period as I have experience with MA cables and know to just wait.....Same with the PH cables, after about 80 hours they exploded with detail and bring out the best in my analog rig. The biggest improvement for me was the PH3's eliminated all the hum I was hearing, very impressive for sure!
