I have a Coda #8 paired with an LA4 and it’s an amazing combination. I previously had a Freya+ and while it’s almost unbeatable for the price and I had quite a lot of fun tube rolling, it wasn’t transparent enough for my liking. The #8 is a standout compared to other amps that I’ve owned to the point that I can’t see ever letting go of it even if I do upgrade (#16?) in the future. I would like to try a 07x or a higher end tube preamp for a bit more warmth, but I’m also considering a change to less bright speakers instead to get the same effect while maintaining the crystal clear transparency of the LA4.
