The Mapleshade website has a piece of audio advice that caught the eye of one our customers, who sent me the excerpt below.
Like most advice, especially Audio Advice, we find that some of it accords well with our own experience and some of it clearly does not. The relationship of good to bad is hard to determine without making a more careful study, but let’s just say that there is plenty of both and leave it at that. That being the case, we thought it would be of service to our customers to break it down in more detail, separating the wheat from the chaff so to speak.
Here is the complete quote:
To get first rate sound and to get your money’s worth from any expensive cartridge, you MUST meticulously adjust VTA or tracking force every 3-4 months — that’s because stylus suspensions always sag with use. This lowers VTA and seriously kills dynamics and treble sparkle. Lots of people misinterpret this as a worn-out cartridge, an expensive error. Instead, raise VTA or lighten tracking force until your test record’s treble sounds too harsh, then drop VTA or lighten tracking force a hair. Your test record must not be thicker or thinner than the bulk of your record collection. Adjusting tracking force yields slightly better sonic results and longer cartridge life than adjusting VTA — and adjusting tracking force on most arms is WAY easier than adjusting VTA.
The basic idea here is that your cartridge sags over time, causing the VTA (Vertical Tracking Angle) to change, which results in less dynamics and “treble sparkle” (a term you will never read on this site; treble should never “sparkle”, but we get the point).
So, with this idea in mind, after doing a serious shootout with Revolver and hearing a Triple Plus side one with amazing bass and energy, we decided to reduce the tracking weight on our Triplanar arm a tiny, tiny, practically non-existent amount, something in the range of 1/100th of a gram perhaps (we do not use gauges of any kind for setup as they cannot be trusted; they have all proven to be much too crude relative to what our ears tell us).
Cueing up Taxman, we immediately we’re knocked out by the amazing bass line that came jumping out of the left speaker. It was bigger and punchier than we had ever heard it! Wow — who knew? I thought it was amazing before. Hell, it was amazing before, the best I had ever heard it, all of ten minutes ago. (more…)
