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 parts and changes to the circuits. We are implementing an upgrade path for the Jolida equipment. We are offering this upgrade path in order to assist our clients to match our units with the highest level of critical sound requirements or help the client improve the sound of their existing amplifier without the cost of getting a new unit. The path will follow five basic packages. 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.
  • Upgrade IV: Changing the internal wire to ultra high grade signal wire.
  • Upgrade V: Use of Alexander Machine Wound Duelund caps either in the output stage or the coupling cap stage or both.

Current integrated and tube power amplifier Upgrade I: The addition of a resistor array to the input and driver tubes, the use of a Naked Z Vishay resistor on the feedback loop, gold pin 12AX7 Tungsol Tubes, hexfred diodes as needed.
Retail Price: $200

For older amplifiers Upgrade I: Replace resistors and add a resistor array to the input and driver tubes, the use of a Naked Z Vishay resistor on the feedback loop, gold pin 12AX7 Tungsol Tubes, hexfred diodes as needed.  Change all the coupling caps to ESA clarity capacitors and custom couplers.
Retail price: $350

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