My humble feed on this.(It is the Sidre btw)
I think the Bergmann LT is probably top tracker in comparison to most LT i had the opportunity to play on.I have seen LT jump around just by looking at the table no names needed to be mentioned
Having the air supply on the carrier and not the tonearm makes a lot of positive difference,as the other way around creates unsolvable issues.
However..The tonearm is light,and it does sounds lighter in midbass compared to conventional ,uni or not.
Also the VTF is not practical to adjust ,same as VTA.
It is one of the quietest TT i had the pleasure to work on though.
Cheers
Stavros,
If you have the opportunity, listen to the new Galder and/or the new Odin tonearm. I don't know how Johnnie Bergmann did it, but it is exceptionally full, with quite good bass/mid-bass.
I do agree the original designs (Magne/Sindre/Sleipner) were different, perhaps not as full in the bass/midbass, thus requiring a cartridge with a little more body.
cheers,
Alex
