DTS Audio Electronics
Mod Shop


There is a wealth of equipment out there that was manufactured either to a price point, or with outdated parts.
These pieces have the potential to be superior to units costing several times as much.

We have proven, mods and upgrades that are guaranteed to improve your listening experience.

Some of our specialties include upgrades to Copland 301 and 301mkII preamps, Quad II power amps,

We also have proven upgrades to almost all of Antique Sound Labs equipment. This well made Asian tube gear is surprisingly affordable and well designed.
However with a little modification ASL equipment can truly shine.

We can also design upgrades for most pieces. We not only bench test them, but we also listen to every piece to see if there is a worthwhile improvement.
