Good to hear from you and RJ I believe this issues you are having are not only happens in Aus.
Really, great inside and depth explanation with your experience RJ.
Its never been so hard decision for me in the past buying a preamp as this time around. I literally started to think of selling my VR4 MK3 and get ML ESL 9 or Living Voice OBX-R2. Hoping to the get the open / transparent / live mids.
As per Jadis experience in my system they went really well but felt had lack of opening in mids, soundstage to my ears, bass grip and control was perfect, timbre, airy. Not to mention its eye catchy on the rack and in the room for anyone (jewelry box). Down side no remote control and the unit had service and checked over for health by local dealer, no mod done still stoke condition with stoke tubes. Overall the Jadis design and engineering is something hard to turn away and this can cost fortune in today world.
On the other site there is literally not much information on the internet on Jadis JSP and not sure about their support worldwide. I believe its not complex to repair them if needed to since its point to point wiring and the caps used are from Philip not really something that high end comparing to caps revolution we have now.
Now for the CJ CT5, I seriously take your input since you had them and also the Prem8A. So definitely can't go wrong on the synergy part here I trust that even without audiencing them. Hence, the capability, of upgrading is always there to bring them to next level. I cannot get them audience as the seller is from Singapore which 700km away from my town in Malaysia.
I have one stupid question here as to number tube used. CT5 uses only 2 tube and even the Jadis JPS2 uses 4 tubes. Are this amps called a fully tube amp or hybrid?
Here are final words is the cost - New CT05 $8,500 & JPS2 $14,000
I've been offered now: CT05 $3,546 & JPS2 $4,985.
JPS2 is 2 box unit without remote control / CT5 single peace unit with remote

Have to say both unit rarely pop up in used market around Sth East Asian region. Have to say this are the only piece of both available right now around here as per my deep search goes around in WWW.
My conquest in making the final decision start almost a week now but still finding difficult to make the decision. Certainly, your sharing was great as I felt of getting close leaning towards CJ but not 100% yet.
Look forward to hear again.
Cheers and appreciated both of your inputs.
