@kairosman I did have the CODA CSiB and KRELL K-300i integrated at the same time. I sold the CSiB to get the CODA 07x and CODA #8 (I also heard the amazing CODA #16 with the 07x). I sold the KRELL K-300i to eventually buy the KRELL DUO 175XD. I sold the 07x, #8, and looking to trade-in the KRELL 175XD for a more powerful KRELL amp. Just not sure which one yet.
I really like the Benchmark LA4 preamp with both the CODA and KRELL amps over the respective integrated amps. Though, both integrateds are very good.
The Gustard was a very good DAC.
