Now have 40 LPs of play on the new Benz Micro Ruby Z low output cartridge. It's a big step up from my previous 6 year old Ruby 3H (high output) cartridge. I'm not sure if it's because the Ruby 3 was getting old or the Z is that much better. The Z is much "fleshier" sounding, more meat on the bones -- I'm not a reviewer, eh? Bass and low-mids are much improved compared to my previous Ruby 3H. The cartridge is very smooth with nice extension in the highs as well.
I am really enjoying this new cartridge so far! And it's the best out-of-the-box cartridge I've had in quite a while. Absolutely no harsh break-in time, it just improves as it gets some hours on it.
