LP12 Modification Frenzy

The “LP12 Modification Frenzy” (LP12MF for short) is the project that got me started on this blog. It consists of a lengthy and detailed step-by-step evaluation of the effect of upgrades and modifications to turntable components such as the subchassis, top plate, bearing, subplatter, cartridge, tonearm, and drive system of my Linn LP12, as well as systems for cleaning records. I’ll use this page to organize my many blog posts into a coherent narrative.

Setup articles

  • Beginning. My first post on the blog, in which I briefly preview the LP12MF
  • In My Room, in which I describe my office/listening room and provide an overview of all my associated equipment
  • The LP12 that I’m About to Dismember, which describes the story and the technical state of my LP12 in its pre-LP12MF state. I also unearthed some Baby Pics of this turntable in its original state.
  • Test Tracks, Test Albums, in which I describe in significant detail many the records and songs I’ll be listening to in the course of the LP12MF. If you’re interested more in my musical interests than my hifi pursuits, this isn’t a bad place to look.


  • Summary of Effects. This is the page where I record brief, digestible, comparable reflections. If you’re looking for a quick overview of the project and its findings, this is the place to check first.

Round Zero: Pre-Modification

  • Listening Test: Before any modifications, in which I provide a comparison of my pre-modification “Base” setup and my digital setup. In the early part of the post, I explain my comparative listening methodology.

Round One: Mober Subchassis

Round Two: Tiger Paw Khan Top Plate

Round Three: Audio Desk Vinyl Cleaner Pro

Round Four: Linn Lingo 4

  • Installing the Linn Lingo 4, in which I install Linn’s “Akurate-level” power supply, whose noisy motor began to bother me shortly after installation (months later, this situation still isn’t resolved).
  • Listening Test: Linn Lingo 4, in which I find that the Lingo made no improvement in my system, and reflect on whether it makes sense to do a listening test with a motor you know isn’t working correctly.

Round Five: SSP12

  • Listening Test: SSP12, in which a cheap and easy-to-install inner platter makes my system sound much, much better, and thereby relieves much of the existential angst accumulated in the previous round.

Round Six: Dynavector XX-2 mkII

  • Installing the Dynavector XX-2 mkII, in which I realize that my custom-made cartridge protractor is messed up and I probably won’t be able to get the XX-2 properly aligned.
  • Listening Test: Dynavector XX-2 mkII, in which, unsurprisingly, I find that my probably-not-properly-aligned XX-2 sounds really horrible, but also come up with many other theories to explain the terrible sounds coming out of this setup.

Round Seven: Linn Ekos 2 Tonearm and Kore Subchassis

  • Installing the Linn Ekos 2 and Kore, in which I curse tonearm leads in cramped headshells and praise the stylish and user-friendly Ekos.
  • Listening Test: Linn Ekos 2 and Kore, in which I find that this very expensive and fancy setup doesn’t sound as good as I expected it to — certainly not as good as the much cheaper Round Five setup — and come up with many theories to explain it, including another seemingly faulty Linn product: an out-of-true Kore.

Round Eight: Mober Subchassis for Linn

  • Listening Test: Mober Subchassis for Linn, in which taking out the wonky Kore and replacing it with the Mober subchassis makes a big positive difference, restoring my sense of excitement in listening to music on my setup and giving me faith that after several missteps, the LP12MF is getting back on track.

Round Nine: Mober DC Motor Kit

  • Installing the Mober DC Motor Kit, in which I detail a very pain-free installation process, show how it works in a video, provide lots of pretty shots of the Mober in action — and give some thrilled first impressions.
  • Listening Test: Mober DC Motor Kit, in which I continue to be thrilled with the Mober DC kit, discuss its clear, dynamic, “sizzling” sound, and decide it’s one of the best upgrades yet.
  • Mini Listening Test: the Adikt Returns, in which I swap my trusty Linn Adikt cartridge back into the above configuration and find that it subtracts some of the previous magic.

Round Ten: Linn Troika Cartridge

Round Eleven: Tiger Paw Javelin Tonearm

Round Twelve: Naim Aro Tonearm and Greenstreet Subchassis

You should try some of the easily reversible mods on the tripping the linn lp12 Fantastic article. Improvements are clear with oscilloscope.

Really enjoying your blog. Reading the LP12 modification frenzy (apt name btw). I’ve been into turntables for about 15 years and it has hit a feverish pitch! I have a 41-year old LP12 that I just did the Cirkus upgrade to – so much better. I also have seven other ‘tables – Well Tempered, Rega, Pear Audio, AR, Oracle, etc.. (I have a problem) Anyway – a note on grgaudio – that guy is a creep. I bought a cartridge from him and it came with a clearly bent cantilever. Anyway – enjoying your blog (and I really like the graphic design) – Greg

Thanks, Greg! And sorry to hear about your bad experience with grgaudio — that was so frustrating for me, sorry to hear you had to go through something similar.
