Internal Wire Upgrade for SME V

Thank you Chakster! Keegiam, unless a wire is broken leave well enough alone. The SME is a fine tonearm. All tonearms are relatively delicate devices. It is not hard to injure a bearing. If that happens you have a Christmas tree ornament. 

Hearsay is dangerous in the audio world. The "service expert" is just as likely to damage the arm as anybody. Accidents happen. 
The SME V has been around for a long time and there are many on the used market. Just like cars audio hobbiests love to hop things up just so they can brag about how special their SME is. 
The only thing that changing your wiring will do is give you bragging rights. In my book that is just not worth the risk. And, why are you not installing your own cartridge? Bouncing your turntable and arm around town is not a good thing to do. Once you have a turntable set up you leave it where it is. If you know how a screw driver works you can change cartridges. The money you save on service will pay for the few tools you need. With the stylus guard on it is very hard to damage the cartridge. 

Ah, the power of suggestion. Any sane person is bound to look like an idiot. Keegiam will have his wire replaced and will think it made an amazing difference in sound quality like Raul and Frogman. 
Keegium, that "expert Tech" is now 30 years older and has a shake and bad eyesight. Anybody who is an "expert tech" would not be in this business. They would be doing something useful like fixing jet engines. You can actually make a living doing that. 
Anytime someone says a minor change makes a huge, amazing, stunning and or phenomenal improvement, RUN away. There is no such thing in tweakdom. Just vivid imaginations. Going from Rogers LS3 5A's to Sound Labs 845's is an example of a huge, amazing, stunning and phenomenal improvement.
