Moots Routt 45 for a bike here 😁
More relevant to this thread, I built an AN Kits EL34 integrated amp a few years back. Great amp and I am still using it. I got the version with the upgraded C core transformers. I love the sound of this amp. The kit was well thought out with good documentation for the build process. I changed out the binding posts for some pure copper Cardas ones, but the supplied Audio Note ones are pretty good quality as well. I happened to have the Cardas ones left from a different project.
I previously owned an Audio Note P3 300B amp and loved it but never got to compare it to one of the ANK versions.
I wouldn't hesitate to go with Audio Note Kits again.
