CODA is not the easiest to sell but people who have heard it are quick to buy. I sold a few CODA items before, CSiB, 07x, and #8. I have the #16 now.
I also have a Sanders Magtech that I really love with my Magnepan LRS+. I was told by Roger Sanders it was first designed for Maggies. The reason I mention it is because I think CODA builds the Sanders amp. I also think the Magtech is a bit better than the #8, not the #16. I bought a 10-year-old used Magtech (refurbished) from Sanders for $4k. I threw out the Magtech shipping box.
BTW - I did some critical listening with the #16 and the Holo Serene preamp this morning with my new replacement powerline streaming (use fibre at the end). The Serene and the #16 sound great together. Highly recommended with CODA amps.
