@christianb5s4 If you do buy a used #16 be aware that there is some special setup needed to be done on the amp before it is shipped. Luckily, the guy I bought my used amp from had it checked out by CODA and they informed him how to pack for shipping. You need to open the top panel and insert provided foam inserts so that certain internals do not fall. This is to be overly cautious.
I just bought the PeachTree GAN400 amp again for $1200. I will sell it again once I have decided on what amp to get later (or maybe be happy with the GAN400 and save money). I was wrong I need an amp in my office immediately.
With the Focals I think I would go with the KRELL. For my Yamaha NS5000, which has a tinge of warmth, I went with the less warm CODA #16. That is how I hear it but a KRELL dealer I am working with insists the CODA is warmer.
