@solypsa, again, this is my personal experience and guides my own cartridge purchases. I have had two wooden bodied cartridges and their sonic performance was not as good as (read colored) the best metal units and their construction quality was not as good. Wood is not a good substrate for a cartridge. Unless it is resin treated wood is not stable, it expands and contracts with humidity. An ideal cartridge body has to be dense, stable and non resonant. Even resin treated wood is not dense enough. If you had to make a wooden cartridge Lignum Vitae would be the best choice and no one uses it! Using a "tone wood" is a huge joke as in cartridge profile wood has no tone, that is it's advantage, it does not ring unless it is planed very thin.
Our definition of a cottage industry differs. It is easier to define not cottage industry as larger, well established companies with a long history of making highly rated cartridges with mature technology. This does not guaranty fine performance, nothing does. As an example, DS Audio does not qualify in my eyes because I do not think it's technology is mature yet. In my eyes Lyra and Soundsmith are not cottage industries. I should also note that it is possible for a cottage industry cartridge maker to make a fine cartridge. IMHO just less likely. I am not going to plop down 10 large on less likely.
@larryi , given the right circumstances the old 57 could be a fine performer. The Levinson HQD system was the first system that I would qualify as SOTA in it's day. It's main problems were reliability and durability. It was neither.
Tubes may in some people's minds sound better but it is relatively rare for them to be more accurate. Human's are instinctively drawn to fire and light. Fire and light are safety and security. I am not kidding. Human behavior frequently has an instinctive basis. Women like SUVs because they place them above the traffic. They like being up higher. Higher is safety. You can see your enemies coming and hide your children. My pack rat mentality in an instinctive behavior. You never want to run out of ammunition.
