The Freya+ is OK with the CODA #8. I forgot if this applies to the CODA#8 but with the KRELL Duo 175XD the Freya+ does not go silent when the volume is turned all the way down. I had the same thing happen with my Topping pre90 (Stereophile review should be out online today) so I sold it. With the Freya+ I figure its tubes, so I let it go. The Freya+ will not stay long term with my CODA #8 or KRELL 175XD.
The CODA 07x preamp is great with the CODA #8 and my KRELL. I use the dual XLR outputs to use with my headphones and speakers. The Benchmark LA4 sounds excellent with the CODA #8. It was not that great with the KRELL, but I had COVID that week when I tried it out so maybe that was the reason. I actually prefer the LA4 with the CODA #8 but I need the dual XLR outputs so the 07x stays. The 07x is also much warmer than the LA4. The LA4 maybe not warm enough for some people. There is a 30-day home trial with Benchmark, so you cannot make a mistake trying it for yourself.
A few weeks ago, there was a used CODA CP preamp on USAudiomart. I was debating whether to get that or the Freya+. The dealer who sold me the 07x told me that the CP is sort of like the 07x and an excellent preamp. He suggested I go with the used CP over the Freya+. I should have listened.
