Buy Back Old or Move On?

I am putting together my retirement system; it has to outlast me (20 years) or at least my hearing. I have an opportunity to purchase back my old Coda CSiB amp which is coming up 10 years old now and recapped in 2019.

I'll be into it for about $3,000 or so by the time it arrives on my door. It will drive KEF R11s, have decent out-board DAC and some form of a steamer for digital music listening only.

Do I go back to it or move forward, any thoughts? If forward, what would you suggest?

Thanks
