Raul,
I think it's time for you to let this topic go, and to accept (as Ralph and I have written) that there is no perfect tonearm. More importantly, the best tonearm for one person may not be suitable for another person.
We interact with machines in a very personal way. Every individual hears differently, so a design decision (design decisions are compromises in many cases) may be sonically acceptable to one person, but not to another.
I don't want to pollute this thread with too many of my own rants, but if anyone is interested, I posted on the topic of "the best tonearm" to my blog (
https://galibierdesign.com/best-tonearm-01/ ).
I enjoyed our time we spent together when you were traveling across the country with your Essential preamp. We will always have our philosophical differences, but in person, you are a 1st class gentleman.
Balancing things out, I never thought I'd bond with Lewm in person, but I had the opportunity to spend time with him and we've gotten along famously. Sometimes the person doesn't translate from the written word (nothing new here).
I'd like to see this gentleman carry over to your online personae, as the individuals who find you abrasive and pedantic are doing so for a reason.
You have a wealth of knowledge to offer this community, but your "virtuous sonic warrior" approach ("my way or the highway") offends many individuals.
Of course, free advice is worth exactly what you pay for it ;-) Finally, a disclaimer: my Spanish is much worse than your English.
Cheers,
Thom @ Galiber Design
