Still have a SYSTEMDEK IIX from the mid 1980's that I bought almost 20 years ago.
Great sounding TT for very little money that has been quite durable, and does scale nicely with a better tone arm and phono cartridge.
How often do you upgrade turntable ?
The table itself, not arm or cartridge.
And when you do, how far do you go ? Big steps, small steps ?
I got my Nottingham Spacedeck more than ten years ago and have no intention to replace it. I would have to jump high for the upgrade to make sense. One day perhaps.
