Cartridge for Denon DP 3000 NE
Intermittent problems like these are often the most difficult to diagnose and eliminate. Sometimes the physical acts required to change a cartridge or IC, the plugging and unplugging can create or mask the issue. Check the solder joints at cartrid...

"I decided to upgrade my turntable in part because a persistent hum associated with the white cartridge wire..." Maybe you should have investigated that phenomenon further before investing in a new TT. White wire usually carries left channel "hot"... 
Considering Revising My Tonearms. Input On This Option Considered
You might begin by swapping the Schroeder for the SME on your Cosmos. Does that improve the SQ derived from the Cosmos? That’s a clue to your puzzle, but different cartridges sound different with different tonearms. So if you swap arms, audition s...

I don’t think any of these commercial devices really protect against a lightning strike. But filtering is good so long as the filter doesn’t unduly increase the output impedance of the AC source.

Pindac, what a pile of rubbish!

Just to say I would not take the advice given here as gospel, not the least reason being that some of it is conflicting and confusing.  I would consult a competent electrician to be sure you are conforming to code, and in addition an audio-savvy E... 
SUT help
Pindac, I have no doubt that what you say is a true summation of your personal experience. I can only suggest that maybe you haven’t sampled some of the very best high gain phono stages. This is not to say that I would argue the superiority of any...

Also, Pindac lives in UK, and Raul lives in Mexico. Electricity codes are different in different countries.

Wow! What a potpourri of opinions! (I have always wanted to use that word in a sentence. Not sure of the spelling.)  
SUT help
Elliot, The phono stages in both of my phonolinepreamps have sufficient gain to handle any LOMC cartridge. I am going to generalize and say they both produce a total gain (including linestage gain) of more than 75db, probably more like 80db. They ... 
SUT help
Ralph, You should know by now that in my case you are preaching to the converted. I do not now own a SUT. Nor have I ever owned one. Furthermore, except for one amplifier I built myself from scratch for the fun of it and because I came into a pair...

An isolated ground may be beneficial from a noise point of view. I am not really sure about that, but I do it too. However, I recently learned that it also can pose a danger, because if there is a fault in the Audio system, the circuit does not ru...

It is said to be a good idea to isolate digital components from the rest of the system, but this can be accomplished via your existing ZeroSurg thing, whatever that is. It is also a good idea to isolate the turntable from other components, because... 
MC-MM-MI CARTRIDGES . DO YOU KNOW WHICH HAS BETTER QUALITY PERFORMANCE? REALLY?
Somehow, two different discussions got twisted together, the questions of whether reproduced frequencies above the range of your or my hearing acuity have any effect on your or my perception of music vs whether one should listen with eyes open or ... 
Tonearm resonance
I'm sorry, but I still don't know what you mean by tonearm noise.  Tonearm bearings can be noisy, but I would think only on a very cheap tonearm.  Anti-skate devices can introduce a source of vibration by several different mechanisms.  But otherwi...
