I posted a long time ago that I first encountered Raul on a VE thread where he declared all MCs hopelessly flawed and/or distorted. This was some time after he started his MM/MI thread, maybe 8/9 yrs. ago? His command of English was much the same as today. Unspecified distortions and vaguely described flaws were hard to dispute and it was a frustrating experience. Now his posts seem longer and more repetitious.
I'm not sure if there was some kind of dispute about someone not getting a purchase from him. I thought of him as basically honest, and still do.
What's really changed is his usefulness to some other members in identifying high performing vintage carts. Some people would wait for his picks or get them by email and invest.
I've heard a couple heavy metal tunes I like, but I'm far from knowing much about metallurgy. Here's what Brakemeier said:
"I am using Timet 1100 Titanium for all my cartridge bodies due to the fact that it combines outstanding high drawing strength with about the highest transition speed in all suitable metals.This I consider of importance to get mechanical induces energy from the tracking process during playback as fast as possible through the tonearm, its bearings and into the base."
This is the same formula as in the review.
Ti-6Al-2.7Sn-4Zr-0.4Mo-0.45Si
Seems like a good idea to me, although I can't confirm the specs. This is what Lewm was talking about earlier in the thread. Most of the mechanical energy of the cart does not get converted to electricity. The best idea IMO is to dissipate excess energy and critically damp any remaining.
