About Quartet Lab
Quartet Lab is a small, independent workshop focused on DIY electrostatic headphone amplifiers.
I began building electrostatic amplifiers around 2013, initially to support fellow enthusiasts who were looking for reliable, carefully built solutions based on well-known designs such as Megatron, T2, KGSSHV Carbon, Grounded Grid, and KGST.
Around 2017, due to a demanding work schedule, I stopped taking external build requests and focused only on building amplifiers for my own use.
In recent years, with more time available again, I have resumed accepting limited build commissions, continuing the same approach I have always followed: careful assembly, thorough testing, and clear communication.
