I spent a good chunk of the afternoon realigning everything starting with setting the cart dead level. After tweaking and adjusting I think I can safely say that at least in my case it makes absolutely no difference in how the cart tracks, or the needed VTF and A-S. Both are practically identical to when I had the cart slightly tail up to get the 92 degree SRA. As to how it sounds, I think I like it a bit better tail up. It sounds clear and mellow (not soft), but I think I like that small extra bit of transient snap I was geting before.
VTF, VTA, SRA, and 92 degrees - question
I'm familiar with the logic that has been out there for a while about setting SRA at 92 degrees for what is considered the optimal styus position, based on a lot of analysis done by Elison and others. My question is, if VTF and VTA are set per cart maker's recommendations (let's discount Anti-skate for this discussion even though it would come into play), then wouldn't the SRA be automatically set optimally per the manufacturer's intention? Assume a cart that is built to the company's design parameters - no bent cantilever, no offset stylus etc.
Take a Benz cart for example. Many (if not all) of them specify a VTA of 20 degrees. So if VTF (and yes A-S) and arm height are set so that when all's said and done the VTA is 20 degrees, isn't that what it *should* be set at based on how Benz expects that cart to perform?
I ask because I set the SRA on my Benz to 92 degrees going by that camp, and when I checked the SRA it was at - guess what - about 22 degrees. That kind of suggests Benz expects the stylus to be at 90 degrees relative to the record. Isn't that how they've designed it? Don't I run the risk of having to compensate in other ways if the cart winds up exhibiting tracking problems at an SRA that does not support the specified VTA?
