DOA Discrete Opamp Colour

Really enjoying it

This is a nice addition to my palette. It’s got a really nice overall effect to the sound.

So good!

I got the 70s bundle and didn’t know what to expect from this module. It came with the Red-25 OpAmp, and I think I’ll be using this one a lot! To my ear, it adds an immediacy and intensity to the midrange that makes just about everything sound better on subtle settings. The distortion characteristics at higher levels are super usesable as well, to add harmonic glue and such. Love it! DIYRE’s service is great as well, if you end up needing it.

Putting spare DOAs to good use

DOA colour is a great way to make use of those extra opamps that didn't win as go-to's in preamps. Preliminary blind testing inidcates that to me, at moderate drive, the difference between DOA colour and the CTX with DOA is minimal. Past 12:00 the CTX with DOA begins to have a more controlled low end, while DOA is less subtle in the lows.
