How are you playing your precious MONO Vinyl?

There is no one answer to this riddle.  VAS offers some great cartridges too.  My collection includes a matching pair of VAS Nova MC, one mono, one stereo, both aluminum cantilever with a 0.07 mil elliptical stylus.  The VAS mono is my preferred mono cartridge for classical.  As I said in a previous post the 2M Mono SE is my preferred mono overall, but I should clarify that preference is based on jazz recordings.  I listen to jazz 80-90% of the time.

It’s all about the perspective under given conditions. You can buy a 10 year old used BMW and fill it up with cheapest gas and not feel like a sucker. 

Would you fill a brand new BMW as a first owner with cheapest gas….may be you will, maybe you won’t. That would be your prerogative. You and I both know, what is a recommended fuel rating for a BMW.

My comment about 87 Octane stems from ownership of Alpina B7 and M3 (purchased new)….would they run on 87 Octane, without a doubt. But a 91 or higher Octane ensures optimal performance and longevity of the engine.

"and longevity of the engine. "

I have not read or been told anything about that. Any links?

A quick search lead me to this Car & Driver article. I am sure you can find more articles around the benefits of using a higher octane. I was bit surprised to see the results for Ford F-150.

High mileage cars tend to lose a little compression and therefore lose the requirement for high octane fuel. I don’t know whether this applies to Elliot’s report or not.
