I just received from BURSON AUDIO a few pairs of V7 Classic Pro and V7 Vivid Pro operational amplifiers for use in audio equipment, so I already started the "burn-in" and I've also played a few songs on my Soloist 3X Grand Tourer (the 2023 model) headphones amplifiers. Many thanks to Burson Audio for providing me the opportunity of testing this new generation of solid-state operational amplifier. I'll do my best next week to write a full review, but meanwhile I'd like to share with you some close-up pictures and a few thoughts as well.
The new generation of V7 Audio Op-Amps sealed in exquisite package
V7 Classic (V7C) and V7 Vivid (V7V) dual op-amps
I remember my first review on Burson op-amps back in Dec. 2013 with the Burson V5 model when I had them tested in my ASUS Essence One MKii DAC (I'm still using this ASUS combo in my living room), then back in Nov., 2016 I reviewed the Burson V5i model, them I moved to test and review the Burson V6 Classic and Vivid as well and I've noticed a clear improvement in sound when installed in my Matrix HPA-3B headamp. For some reasons, I did liked the V6 Classic model more than the V6 Vivid, although most other head-fiers were in love with the Vivid, so I'm looking forward for your thoughts on the new V7 Pro model: Classic vs. Vivid opinions.
The V7 Vivid Pro models are already included in the Deluxe Package of Burson's flagship Soloist Voyager and installing these op-amps in our Hi-Fi gear should be a no-brainer for DIYers and modders.

This new generation of solid-state op-amps is biased into Class A operation much more than the previous generations of Burson op-amps, so they will run finger-burning hot while in-use. This is normal for these op-amps, hence the aluminum outer shell acts as heatsink ensuring a better thermal stability too. For modders and DIYers, you should wait for a few minutes after switching your audio equipment off before unplugging the V7 Pro op-amps, otherwise you could injury your finger (however, you should never hot plug op-amps anyway).
Burson V7 Vivid has a couple of resistive trimmers on two sides used for bias voltage/current adjustments.
You should never touch those trimmers, otherwise op-amp will get damaged (in time) and warranty will be voided!
V7 dual op-amps contain two small PCB's inside, each one terminating with gold-plated pins
All the transistors inside the V7 op-amps are thermally linked to the aluminum outer shell that acts as a heatsink. Burson was using both thermal pads (on the outside) and thermal paste (on the inside)to cool-down the internals.
I am repeating myself now, I know that, but you should never adjust those trimmers! It takes hours for Burson engineers to fine-tune each op-amp! Hopefully, in the near future these trimmers will be sealed with special wax. Meanwhile, anyone playing with these trimmers will void the life-time warranty, so take care.
V7 op-amp inserted into gold-plated DIP-8 socket. A dedicated O-ring (included in the package) needs to be installed under the socket, prior to get it soldered onto the mainboard.
The DIP-8 sockets are for DIYers that want to solder them directly onto the mainboards. They are high quality gold-plated sockets, so everyone can use them without worries because there will be a very good electrical contact between the op-amp and the socket. There are also dedicated O-rings that should wrap-up the op-amps from under the DIP-8 sockets before soldering.
