I have been testing the Glanz G5 extensively and I've grown more impressed with each comparison that it has undergone in relation to other renowned cartridges.
A curiousity around its stellar performance is the fact that I use mine in my Audiocraft AC3300 tonearm with the s-shaped wand. This means that overhang and off-set are way off the standard and, obviously, cannot be adjusted in their permanent headshell. Nevertheless, the Glanz outperforms everything that has been reviewed in comparison to it. This finding being based on my own criteria of assessment and reference to specific live performances at familiar venues. Simply phenomenal but difficult to find!!!
If the Glanz G7 is indeed an improvement on my G5, my mind is literally boggled. I should suggest that although the G7 claims better performance parameters statistically, you need always to be careful in following these as the sign of a better cartridge. Similarly, one needs to be careful in accepting a manufacturer's necessarily claimed hierachy of its products. These often fall back on a parameter of improved statistical behaviour, with prices and performance being seen as increasing year-on-year. Only careful auditioning will tell the true tale (a case in point here being the ADC XLM range).
If you get the chance and love live music (and your system is generally up to it), the Glanz G5 cartridge simply demands your attention.
