Product information

DAC upgrade program for 1st gen WA7 customers. The upgrade would replace the entire digital section in your unit. This includes the new 24/384kHz ESS SABRE DAC and XMOS USB controller with “high retention” USB connector (orange color), premium Teflon tube sockets and new LEDs. This is the same digital section used on the latest 2nd gen WA7 Fireflies.

- for domestic CONUS customers, the cost for the upgrade is $499 which includes parts/labor and return shipping by FedEx Ground. 

- for international customers, the cost for the upgrade is $499 which includes parts/labor. Return shipping cost will be invoiced.

For customers with WA7tp (tube power supply), we offer Teflon tube sockets upgrade for $99 (return shipping included). They are the same premium sockets featured in WA7 DAC upgrade. This is optional as it does not impact the sound, only the visual effect of the tubes glow. Teflon is a more porous material so the LEDs under the tubes glows slightly brighter. 

Please complete this form if you’re interested in the DAC upgrade.



  • 1st gen WA7 Fireflies only, not compatible with WA7d Fireflies Duo
