In the end, I would put a properly configured $7000 (or $12,000 or $26,000) LP12 up against any other turntable at the same price or even higher. The LP12 is an exceedingly musical turntable and I have had a number of customers buy one after comparisons with similarly priced or more expensive turntables. But you do want to do the upgrades sensibly and from the little information you have given on the proposed upgrades I don't think they fit that description. I hope this helps. ThomasOK.
Repair Linn turntable vs buying a different one
Dear turntable experts:
I would very much like you opinion and recommendation if I should go ahead with repair my old Linn LP12 turntable system which has Karma cartridge and Ittok tone arm. If the repair job include replacing with Krystal cartridge and Akito tone arm plus Linn cable and other misc parts, the cost of parts is about $6000 plus labor, with estimated cost of about &7000 total. Would there be advantage of proceeding to do the repair of the Linn turntable system vs. buy some other turntable at equivalent of $7000? Thank you very much.
