Default Ref 2SE Custom loading




Installed 75ohm resistors into the custom loading space of my ARC phono ref2 SE.

Source 5 - ROON ROCK with Aurender W20 as NAS & 2 units of SOTM switch with 10M input (the new frontier but still cannot beat CD for now) - ROON endpoint - Vivaldi upsampler

Amplification - Naim Statement

Speakers - ProAc Carbon 8 + JL FM113 x2 (replacement purchased - Stella Utopia EVO but due to lockdown, could be a year's wait)

Purepower 2000 x 2 (&$@#% but
sounds nice)

Default 75 ohm resistor
Hey Joe,

Are the new resisters the larger blue ones with purple-green-black on the right side of the picture? Why did you choose ones that are larger than the stock ones for impedance loading? Would this void your warranty if it's a DIY project?

Thanks for sharing.

Wilson

Yes, those are tantalum ones bought from parts connexion.

I have had my unit a couple of years already so I think no more warranty.

... tantalum ...
Nice job.

In a sonic comparo of several resistors with different values, the Tantalums were my fav followed by the nude Vishays.

Vishay S102 (nude)

ARC has a three-year warranty. But I think so long as the resistors were properly installed - and it sure looks like they were - the warranty is still valid. The resistor installation is simply using a feature designed into the preamp.

Hmmmm, I really can not see ARC going for this, unless by prior agreement with them and the work undertaken by an ARC approved tech.

Is ok.

The main point of this thread is to show that it is not so difficult to do this oneself if warranty is not an issue.

But in the future, I will be more alert to the warranty issue. Thanks for the reminder fellow forumers.

I've read the warranty and don't see any language in it to support your fear.
