If you have an LP12 languishing in the corner it may be time for you to bring it up to spec and disuss with the Linn "fettler" your upgrade options.
I bought the Akurate Radikal power external power supply/upgraded motor kit for like $4100. This was when the Karousel bearing upgrade was released and it was valued at $795 but being given away "free" if you spent at least $4,000 on other LInn Products. The Green Street Audio "Keel clone" supbase was another $795 and I want to say that the Adikt MM cartridge was like $650. He charged me a fee to take my LP12 apart and set it up properly, something like 200$.
So, yeah, adding all that up I just came up with a quick number of $5695. Any other time I would be complaining that this is too much but at this stage in my life it just sort of came together and the upgrade that I just knew was a possibility has happened. I had some extra cash for this so I was delighted.
BTW - my Bryston MM phono stage retailed for another $1150 or so all in all I’m now talking about $6795 to get it up to spec but man I’m loving my vinyl record collection and picking up new titles again.
