I bought my LP12 around 9 years ago. For me it’s option 2. Numerous upgrades!
It started off with a black ash plinth which had been sanded down and refinished in a maple colour. It matched my Fraim shelving which is maple and ash.
It had an Akito arm, Goldring 1042 cartridge, valhalla power supply and pre-Cirkus bearing. The first things to be done were a Lingo 1 fitted and the Akito rebuilt by Audio Origami, who upgraded it. I got the Lingo 1 fitted as I wanted to play 45s with ease. I used a Graham Slee MM phonostage to start. This was now a lovely, serviced turntable. My dealer recommended a Cirkus bearing and Kore.
After getting those bits done the LP12 was left like that for a few years.
Next changes were Karousel bearing as per dealer recommendation, cart change from MM to MC Dynavector XX2 MkII, Tom Evans The Groove + MRX power supply phono stage, Ekos 2 tonearm, Trampolin 2 fitted. This really lifted things to a whole new level. The LP12 sounded superb at this mid spec level.
About a year later I was very ill, diagnosed with Stage IV terminal cancer and decided to take my LP12 to Klimax Level. This was Klimax Radikal 2 power supply, Urika I, Kandid cart, Keel, Ekos SE/1 as well as having the Karousel already.
A year after that new top plate, Walnut fluted plinth, new lid and hinges all fitted.
So now none of the original parts remain. It’s a new turntable built with new and some used parts. It does sound epic! I thoroughly enjoy my LP12 and always have done.
The sweet spot was the middle ground Kore, Karousel, Ekos 2, Dynavector cart, Lingo 1. I would have stayed put but did a host of upgrades as part of combatting ill health.
The upgrades and my system became my solace in dark times! The LP12 has not been without problems with Ekos SE/1 having to be rebuilt by Linn.
I have enjoyed all the different variants of the LP12. The first entry point was a wonderful turntable once the Akito was fixed. The LP12 is not for eveyone as there are so many variables, and potential issues. Tonearms have been my problem, other than that the LP12 has been reliable.
