voltage and current burn in
« on: May 16, 2022, 10:20:01 PM »
I’ve had the Hagerman burn in devices for a while … Frybaby3 for cables and Frycorder2 for power cords. They work great. Nowadays I don’t want to spend time listening for many hours to monitor changes in SQ.

When I read the user manual for the first time, there were instructions for a voltage and for a current burn in. I’d never heard of this before. The voltage burn in mode is for 2 days and requires the cables are only connected to the device on one end. The current mode is 3 days and the cables are connected on both ends to create a loop. Here’s a link from the Hagerman website

There are other burn in devices on the market, but I’m not familiar with them. Do most of the other devices use both modes or just voltage or just current? Ultimately, if there are enough hours on your system, does it really matter what method(s) are used to getting the maximum performance out of the cables?

Good question, how many more devices are there?

All of TWL cables are preliminary "burned-in" using a High Power audiodharma Cable Cooker prior to shipping...

So there!

  Agree Cable Manf should burn in 100%. Some cables were over 500 hours to stop changing. Do not get me going with Rhodium plugs and receptacles. Torture but when done worth the pain.

Companies that sell large volumes of cables will be hard pressed to do this. Smaller companies like TWL and me (in the past... and sometimes now) do this. 

When I get a batch of wire in I find the destination end of the spool and hook it up to a load and burn the whole spool for about a week.  Then, when I build the cable(s) I burn them for a couple of days, typically.

My burn-in device is a 3A 48V transformer with a variac controlling the voltage that has a random noise generator hooked up to the whole thing that cycles from 2Hz > a couple of GHz that was an inexpensive buy from eBay and it works well.  The 3A @ 48V transformer really doe the job on power cables and speaker cables.  I have switchable loads from 1 ohm to 500K ohms.

I can also run this puppy hooked up to wire when I cryo it  :thumb:  That method takes 3 days...

I have a batch of wire hooked up to it as I type.

OCD at it's best.  I'm so me...
