To provide our clients with a more customized needs approach to sound, we at Jolida have spent the last two years refining and testing our units with different electronic parts and slight changes to the circuits. We have implemented an upgrade path for Jolida equipment in order to provide our customers with the tools to craft sound to their tastes. The path will follow five  basic packages that can be a single upgrade or a number of upgrades. It should be noted that there will be minor variations depending on the given Jolida model. The five basic categories are 

  • Upgrade I: Resistor, diode, capacitor and tube upgrade.
  • Upgrade II: WBT Speaker Post, Cardas Input Jacks
  • Upgrade III: Addition of bybee rails. Please note that not all units can have the bybee rail installed. 
  • Upgrade IV: Changing the internal wire to ultra high grade signal wire.
  • Upgrade V: Use of Hi End Capacitors eiither in the output stage or the coupling cap stage or both. Regarding the placement of hi grade capacitors, we primarily use Rike oil and paper capacitors, Audyn True Copper Capacitors. Call for pricing if the capacitors are not either Rike or Audyn.

We think each one of these upgrades builds on the excellent sound of the standard units in terms of greater clarity, larger holographic images and spatial separation. We will keep you updated on the additional of further upgrades as we finish testing. One upgrade which we have not outlined in detailed is the use of Naked Z resistors in the signal path. Best to call us to see what the options are.

If there are any questions regarding upgrades, please contact Jerred Dunkerson at 301-953-2014.
