Dear @mijostyn : That " free movement " that unfortunatelly the Townshend tonearm can’t achieve is the real key to stay nearer to the recording if and only if the tonearm in use is a good damped design.
All what heppened in my room/system using that " key " was nothing " tiny " but higher improvement that I was not expecting and prepared too and that I had to increment the SPL in my subwoofers says a lot about because is not only that distortions goes lower but the clear definition of the low bass that’s not an easy task to achive. Overall I’m really happy .
Btw, of the really good vintage tonearms that I remember and owned only the MS MAX 237/282 came with a silicon tray that the owner can use using two different silicon density depending of the cartridge in use and MS gaves a list for the cartridges for one and the other silicon density.
Today those vintagey or new tonearm not well or undamped designs always could be benefiated by a not to wide riboon around the arm wand in an helicoidal way. Iyt does not affects the tonearm EM and improves the cartridge resolution during listening sessions.
About your MC Diamond maybe needs more playing hours.
