I mixed and matched the following with terrific results.
- CODA 07x preamp
- Benchmark LA4 preamp (sold my HPA4)
- CODA #8 amp
- Benchmark AHB2 mono amps
Benchmark VS CODA is a simple one for me. The Benchmark is a bit clearer, detailed, and quieter. The CODA is a bit warmer, more powerful, and bit more relaxing with a bit less detail. Now I heard the CODA #16 amp recently (with CODA 07x preamp) and wow, maybe the best amp I have heard.
