I bought this cartridge which was new in April 2009, from a guy on this forum, so I could try out the Source TT which I had just bought. I have his original purchase invoice from Harrow Audio. When the cartridge came boxed it was sent unopened to J7 with my Alphason Xenon which was to be rewired, and I asked J7 to mount the cartridge for me. When I got the rewired arm back a few weeks ago, I mounted it back on the Source, but I could only achieve inconsistent playback, some records worked others did not. In an effort to identify the problem I want to Noteworthy Audio yesterday, who checked over both the Source & Xenon then found that the DL-304 cantilever was not straight when under pressure on the record. I am offering this cartridge for sale, in the knowledge of the above, can it be sorted out or at the worse used as a trade in.
