That's an overly simple assumption. The sonic problem you described could be caused by many things.
There's no obvious reason to suspect an arm/cart mismatch. The UNIverse is actually quite forgiving as to tonearms. It sends less stray energy into the arm than many cartridges and your arm is of a suitable effective mass. It's possible, but I don't think it's likely.
Arm/table mismatches are rare and usually involve heavy arms messing up the springs on a suspended table, not your situation at all. High mass, unsprung tables can handle pretty much any arm that will fit.
For the female vocal problems you described I'd suspect, in no particular order:
- cartridge too new/not relaxed yet
- phono stage overload/slewing distortions (have to try another to know)
- cartridge not properly aligned with Mint or Wally protractor (no acceptable substitutes AFAIK)
- VTF not properly fine tuned (.01-.02g above the mistracking point)
- VTA not properly fine tuned (cartridge close to level or a hair tail-down)
- Antiskate not properly fine tuned (reduced to near zero)
- Resonances being excited in the platter and/or idler drive mechanism (haven't heard a Lenco, no idea what level of performance it's capable of)
We used to have problems like yours with certain passages, but as our system and setup improved those problems have been eliminated. The problem was not the cartridge. Today, no female vocalist on any LP fails to play well and cleanly, whether opera, jazz, blues, pop or whatever. But you have to work at it and everything in the system has to be right.
