@goodnightpaul as an aside, I did not listen to too much Jazz or CD prior to being loaned one of a friends built versions (they have four versions in total).
Jazz was used on Vinyl at a few demonstrations on other systems owned within the Group. I now have approx' 20 Albums purchased over a reasonably short periods, with the last one being a Crowd Funded one I discovered on this forum and only arrived at my address very recently.
As for CD's I went from a small batch of in car CD's to a collection of a few hundred in a similar timeline.
I am having a Four Chassis Monoblock Balanced Korg B1 built for myself, the Parts list is now complete and purchases have started. The Volume controls are Bespoke Built to meet the requirements of this design (not cheap), but I am hoping such accuracy is the attention to design that sets it apart.
This will most likely be out on loan for a while, as I am without a set up system, it is ready to go into storage.
A friend is slowly going Balanced from Bespoke Built Tonearm > Head Amp' > Phon' > Pre - Amp > Power Amp', my Balanced version will fit in nicely in this system for a period of time, along side their own Balanced version, the A/B comparison will be looked forward to.
