best upgrade for 'standard' LP12


I have a Linn LP12/Rega RB300/Grado Sonata which is level and on a good (Audiotech)stand, and am wondering what is a good upgrade that does not involve tearing the table or tonearm apart?

Are the Linn upgrades a reasonable alternative to the Origin and others that are highly touted?

I do not have the trampolin or Lingo, what kind of improvements do these make?

The sound I am getting now has a little midbass ripeness (or lack of definition in the mid/lower bass) and is slightly thin in the upper end. The midrange is very nice and has an intimate quality and the 'Linn beat' seems alive and well.

Overall I am very happy with my setup but wonder if there is a few simple lower cost things I can do that will help these areas.

thanks

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.
Praudio - I am curious to know more about the change you made to the stock power cord. Which power supply do you use and what aftermarket power cord do you use?
Praudio, I am also curious about the power cord. On my LP12 the power cord is hard wired in. How to change it out?
BTW I sit my table on a Seismic sink which really sounds amazing.. big improvement IMHO.
