best upgrade for 'standard' LP12

Ultrakaz,
I respectfully disagree. I did the LP12 upgrade path starting with Lingo (my LP12 already had Cirkus) and then arm. The power supply (Lingo or Naim or Origin Live) are HUGE improvements and should be considered first. The Lingo upgrade is expensive, but not as expensive as buying a new table. And when you're done, the LP12/Lingo combo is a much better turntable than the VPI Aries, Teres or Origin Live entry level models.

I think the best money you could spend would be to ditch the Grado and pick up a Dynavector cartridge. It will seem to do almost everything a Lingo will do - although the Lingo or Armageddon are definitely worthy upgrades - for a lot less money. The Grado adds to the LP-12 "bloom" in the midbass, and a Dynavector will tighten it up A LOT - and increase detail & dynamics in the top end as well. A DV-10X4 MKII or, if you can swing it a DV-20XH, will improve your system the most, for not a ton of money. Make sure you buy the cartridge from someone who knows how to install it - there's no faster way to ruin a good Linn than just slapping a cartridge in the arm and thinking it will work perfectly. There IS a skill to cartridge installation - so seek out a qualified dealer - please!
Best of luck,
Ed

By far;the best upgrade for a stock Linn is the AC cord ...
you will be good for longtime before next move.It's dramatic

thank you Egross but my pre amp needs a fair amount of signal which is why I bought the Grado (4.5 mv version) the Rogue is known for having a little noise in the phono section. Plus my cartridge is pretty new so I will stick with it. I had considered the Dynavectors in the beginning.

Praudio thanks for the vote of confidence on the PC I will do that the next time I get my Linn tweaked.

Put the LP12 on a wall shelf and then later on get the Cirkus upgrade, both of these will greatly improve the LP12 sound and will take away any midbass hump.
