@amorstereo -- Thanks, Teajay! This is the first time someone has explained the difference between Pass Labs and Coda in a way that I can understand. Getting CODA separates is probably outside of what I can afford in the short term, but I remain interested in the CSiB. I currently have two systems in the house. The main one is composed of Harbeth SHL5+ driven by Luxman 590 AXII, and the second one has Harbeth M30.1 driven by Raven Audio Blackhawk. My plan was to replace the Blackhawk with the Luxman, and buy a Pass Labs INT-60 for the main system. But you have me thinking about CODA once again now. I actually bought the CODA from a fellow a'goner but unfortunately had to return it due to unforeseen circumstances.
Now, from what I understand, there were some changes that took place somewhere around 2019 that made the CSiB even better. If I were to buy used, is there a way to find out if the CSiB has the latest improvements? Also, I'm not sure if PL XA-25 will have enough juice to drive the SHL5+, and I want to build my system around these speakers. Another route I can take is to buy the CODA amp and drive it with the Luxman initially, and then eventually buy the CODA preamp once I can afford it. Lots of choices, but you really have me considering the CODA brand seriously once again.
Thank you for the detailed and on point feedback.
