In the 42 years I’ve had my LP12 it’s had many upgrades. The only non-Linn part I’ve had in that time is the TA Karmen top plate. I found it a worthwhile improvement over the standard Linn top plate which I’d had for 37 years. Other than that…… Linn all the way (oh, and a TA Evenstar but I’m categorising that as an accessory rather than a core component)
Maybe Revolver later this year?
So not ‘no improvement’ so much as ‘not worth the money’ and ‘not everyone preferred it at all, but Ivor is keeping one’? Interesting.
To my eyes, the version pictured is very different to the TA product, which has much more internal bracing (and thereby far more machining needed). Apples and pears?
I’ve had it a couple of weeks and just done my 1st comparison with the latest “Father John Misty” record as it has a fair bit going on including orchestral tracks.
It does make a difference and seems to add a little more definition to the sound, without it becomes more airy and lightweight. Also had a tick on a track and with the stabilizer it was gone. Will try again another day on a different record or two to decide if I will keep it or not but positive for now.
There have been a few digs at 3rd party components on LP12s on this thread. My 2 pence:
It seems to me that there are two types of supplier of 3rd party products.
Ivor has a museum of previous production items and trials.
I’m sure none ever get played. 
Especially the Cakes. 
Or tangerines
Another two types of 3rd party product:
Geoff at Soundcraft in Ashford certainly knows what he’s doing with a LP12. He’s looked after mine for years.
I found out from my dealer that TA is changing its the top-level domain of its website from .com to .co.uk.
I have updated my post with the information that I got from my dealer.
If any damage has been caused to TA as a result of this episode, it’s entirely of their own making. After all, it was TA’s botched transition to a new top-level domain that took their website offline.
Would you be comfortable with these two categories?
Examples might be cartridges and phono stages.
Examples might include power supply, arm, sub-chassis, baseboard (or lack of same), suspension and arm cable.
Of course, some items may move from one list to another, depending on whether Linn themselves have done a U-turn and released a replacement or alternative item.
Bit off topic but need to warn vinyl lovers here that there is scam ongoing via Discogs. I was seconds away from being trapped in it. Be careful! Never give credit card details away.
I quite like it that having a Naim Aro is heresy. As for my sub-chassis, eternal damnation for me? 
Also me @Collywobbles 
BTW what sub chassis are you using? Mines the Tiger Paw aKula.
Edit: spotted you use the Stack Audio, nice 
If you both look at my attempt at a more specific thread focusing on just one non-Linn upgrade (or is it?), you’ll see that heresy is a mild description from some perspectives.
FWIW, I had only a brief talk with Theo Stack and eventually went down a different route because of the Stiletto package that I was offered, but he seemed to have a very good grip on what he was doing, and to be patient and helpful. It is a pity that it was not worth his staying in the non-Linn upgrade game.
Thanks, but it might be useful to post in the general vinyl thread with more of an explanation of what is going on (particularly for non-Linn users).
I’m not that particularly concerned about defending the holy sanctity of authentic Linn LP12 components even though they do tend to set a very high benchmark of quality.
I can understand why some feel the need to keep their LP12 pure linn and sidestep any faffing about with the demonic aftermarket 
However, the LP12 has evolved into a multitude compilation of alternative electrical and mechanical parts; even if one has an all genuine Linn LP12 it can be very different from other LP12s even if the difference is slight and merely comes down to the plinth woodgrain. When one dials in numeral choices of genuine Linn components both old and new; plinths, sub-chassis, arms, cartridges, phono-stages, power supplies, it becomes less common to find two LP12 more or less exactly the same anyway.
Using aftermarket parts is a decision of the buyer/owner, the only thing that matters is he/she is happy with the alternative part fit and the performance change it brings.
