Internal Wire Upgrade for SME V

No, you don't have to. It's not necessary, you'd better upgrade a cartridge. Silver is not better than Copper even if you want to believe it is better. 

Replacing stock cable is the last thing you can do, really.

There are many more things in your analog chain you can upgrade with much more noticeable results than an internal tonearm wire.

I would probably go with AudioNote instead of these cheap kits, but - why not?

It’s up to you.

I have replaced internal wires only when original was broken.
Been using Cardas, Discovery, Van Den Hul silver, never used Audio Note silver (that one is the most expensive).

I use many vintage tonearms and I have no intention to rewire them, the sound is nice as it is.

As for the external wire I can’t hear a benefit of silver over copper, so I am skeptical about it (snake oil).

Once I bought EPA-100 tonearm I asked the seller to rewire with his "expert" and there was a problem with ground after I received my rewired tonearm. Sometimes it’s better not touch/replace anything if it works fine.

But I agree than manufacturer can do the job properly, but their price is usually higher.

The stock cable on SME V tomearm is GOOD ENOUGH, period.

Internal wiring Capacitance 15.0 pF per channel
Resistance 0.5353 ohms per conductor

It was designed and used by SME engineers for any cartridges mounted on this tonearm, and this is NOT cheap old junk tonearm that require cable replacement.

If you think someone knows secret formula of the silver that is superior to everything else than it’s like saying that SME engineers know nothing about phono cables.

SME V stock cable is the last thing to replace in analog system.

In my opinion once you're buying a High-End tonearm on SME V level it's better to stick to the original tonearm internal cable unless there is a problem you can't live with. 

There are some people who always think they are smarter than all the engineers who actually design legendary toneamrs. In my opinion you'd better trust original designer and his choice than a stranger. 

You can give a call to SME if possible 

 

Everything makes difference, if you like KONDO why won’t you just buy his entire system (his speakers and amps) ? Would be even more difference. There is only one problem and it's the price.
