I need HELP with my LP12 based system

Thank you all for the comments. One option is to wait a while and then invest a larger sum in a new front end. The PH5 and VTL are relatively new to me and are letting me hear lots more of what the front end is doing. Thsalmon, the table was tuned up about ten months ago when I got the cartridge. Still, it may be worth replacing the arm wire and getting a fresh tune up to see where it goes. Audiophilia is a terrible illness. How I envy my daughter and her love of her purple Memorex boombox!

The bass problem that you are having is due to a weakness in this turntable's power supply. If you want to keep the linn., add a lingo power supply. This should resolve the problem.

Pscialli don't be tempted to spend any more on your Linn. None of the (expensive) upgrades suggested are good value and they will yield only incremental improvements. Accept that your table is a flawed design that has one redeeming feature - its lucid, dynamic mid range.

No matter what mods you do to a Linn you will still have a cheap motor boouncing around on springs driving the platter by a rubber band. It's impossible to get good speed stability with that technology.

To approach the quality of your digital source you really need a massy unsuspended turntable driven by a mylar belt or a direct drive motor.

I do not believe there will be any absolutes (solutions) provided here - too many possiblities, biases, and experiences from imperfect human beings. However, as you gain considerable time purusing internet sites, you can gleen some useful information (though most is useful primarily for looking into, not absolute fact). FWIW, Clearaudio cartridges are not known for exagerated midbass (lean if anything), though I suppose it might be possible that cartridge/arm resonances might be responsible.

It seems reasonable to expect that more modern TT designs using more exotic materials and designs would be able to surpass the Linn LP12, though some of these look ridiculous (perhaps necessarily so, though). You would think that simpler is better, at least correctly executed, but that is another topic. Though it has not always been the case, my own more recent experience with the LP12 suggests that a bloated mid-upper bass is not unusually present: my own LP12 (Valhalla-Cirkus-Akito II) does not have any more emphasis in this region than my Ayre CX-7 CD player. I am being honest about it too.

On the other hand, I am running a Linn cartridge on a Linn arm, though the cartridge is only a K9. Maybe the cartridge is light in these areas? You see, no absolute answers. Oh, having the turntable (non Trampolin) mounted directly on the top shelf of a heavy MDF based rack did have the sound richer/heavier than I liked. Placing the TT back on a small, light oak platform with adjustable feet (screws), purchased back in the 80's, did even everything back out.

Note I have not suggested in any way that the LP12 is the ultimate TT (I have not directly compared to the best of the others I have heard), though I will say that I do believe it is a very good way to really enjoy listening to LPs.

I'm sorry that it sounds harsh, but I'm with Flyingred. His reasons are my reasons.

Thsalmon,
You have a Simon Yorke table on order. That's a fairly good move IMO. Why not preach what you practice?
