SL1200GAE New Tonearm

I put a Jelco 750D on my 1210Mk5.  Decent improvement.  I also put an Origin Live Conqueror on of my 1210 Mk5g.  Waste of time.  Standard arm superior.
I like the look of the brand new Jelcos.  Visually they will fit with the iconic Technics look and I can only imagine they will be better than the older Jelcos that were decent.

@chakster Because silver wire makes a significant improvement on small signal level phono. 

Silver or Copper it is all depends on individual preferences, there no absolute. I've tried Silver Van Den Hul on my old EPA-100, but i use copper since that on all my tonearms. Also what's the point to use Silver inside the tonearm tube if the external cable is copper? 

Cardas or Discovery thin and flexible tonearm wires have the best value. Zu Audio Mission Phono RCA copper from ebay has amazing value. 

Also no problem with stock wire inside some nice vintage tonearms. 
  

@chakster Cardas was the worst wire out of any I've tried, IMO. Just lazy and indistinct sounding. van den hul MCS150M is my favorite. 

Just because the tonearm cable is copper, it doesn't mean that the silver tonearm wire portion will not have a positive impact. From my experience, it has a very big impact. 

I use silver plated van den Hul 501 DIN to RCA tonearm cable, comes stock with SME. So far I haven't found anything better.

For removable cartridge leads, I've settled on Ortofon LW 800 S, which is a mixture of solid silver strands and silver plated copper. 

I don't use silver anywhere else in the system as it becomes overwhelmingly too much. I find copper to be better. 

I have no idea how you can compare the tonearm with one set of internal wires to the same toneam with another set of internal wires. You must have a computer memory as the rewire process could take a few hrs. Or you need multiply samples of the same tonearm to compare. Cardas copper set of 4 litz wires for tonearm is $25, Discovery wire set is very close in price (nice high quality, affordable wires for everyone). As i said no problem with stock wires in good tonearms, i think GAE is one of them.

I can compare for example Reed 3p tonearm that comes with ultra high-end cryo treated cable from cartridge pins to phono stage to some nice vintage toneam with stock internal wires, detachabe headshell and din connector in between and it is not necessary that cryo treaded ultra high-end expensive wires will make the sound of Reed more pleasant.

Much more depends on the cartridge, if the wire is good it will be the last thing i will change. I’m not gonna rewire tonearm 5 times to try different wires, but i would rather change 5 different cartridges. I think i already find nice interconnect and speaker cables made by Chris Sommovigo (Stereolab, Stereovox, and now Black Cat) this guy designed tonearm cable for Continuum Cobra tonearm.

Very good or ultra high-end tonearm cable is the last thing to bother (imo), the difference in price is huge sometimes, only if you have find your absolute reference cartridge and tonearm and everything else then it’s time to experiment with different tonearm wires. I believe we do not use bad cables and it make sence to change something if we’re not happy about the sound. But what if we’re happy about the sound?

Some audiogon members always advice to another members to change something or upgrade something before the buyer even start listening to his new turntables (GAE for example). It’s endless quest how to spend more money instead of enjoying music with a nice gear.
