I have a CODA #16 and use the Benchmark HPA4 preamp with it. I also had a CODA #8 at one time, this is similar to the Schitt Wotan amp.
I have tried the following preamps with the #16, #8, and the Wotan.In order of preference:
- Benchmark LA4 and HPA4
- Holo Audio Serene (a warmer LA4 and HPA4)
- Schitt Mjolnir v3 (no remote)
- Schitt Kara F
- CODA 07x
- Schitt Freya+
I will need another preamp when I move to my next house. My HPA4 pre currently runs 2 systems. My 2nd future preamp will be for the CODA #16 amp and it will either be a Benchmark LA4 pre or the Raven Revelation tube preamp.
