Jadis JA30 Mk2, how great???

Gary, the CAT preamp is the heart of the system...you can work around it, but it will be the strength of your system with most any ancillary gear....like you said it is the engine. Before, I think you were working with a 4 cylinder motor....now you are working with a 12 cylinder motor.

What I have noticed as of now with only 20 hours is its drive performance and refinement. Moving the soundstage back about 3 rows the whole room is now just full with massive 3D weight. The CAT Black Path has a lot of caps so many hours to go. Wow!
The 4 ohm tap and 8 ohm tap on the JL5 CAT amp. have two distinct purposes. On the Gamut RS7i speakers on 4 ohm the speaker exhibits more control but is not as extended or open. Now with this preamp. I prefer the 8 ohm tap for its openness. I have learned that even though your speaker might be a 4 ohm speaker (the Gamut is 4 ohm down to 2.6 ohm at 120 hz) it does not mean the CAT amp. cares. Further reading in the manual Ken Stevens reiterates the 8 ohm tap will likely sound better on electrostats.  Now moving to that tap I prefer it also. 
I know initially I had trouble giving up remote volume control but the longer run of interconnect fixed that. Now I am afraid I have created a lazy man situation where I am 18 inches from all settings. The only time needed to ever get up is to change a record and then it is 2 feet away. I can change CD's from my listening position.
Now in retirement this is just pure heaven having this type of sound. 
I have a good 30 days of break-in for the cables and preamp. yet and I am shocked how it good it is already with more to come.

Hi all, I am the new owner of the Jadis JA30 MKII. May I know about how long it needs to be burnt in to achieve its full potential? Newly fresh out from the box which was already pleased me so much for its precise & detail sound! I do believe it need to undergo a long journey before it becomes stable, isn't it?

Moreover how to compare a JA30 with its SE300B? If output driving power wasn't be a concern?! I have much interest to get a pair of it as well？How would you all thoughts about its performance? Though it wasn't a single 300B tube amp, it still caught my attention for a push pull  single ended type of amp which just deliver a 10W only power. It should have plenty of driving power?! Is it? Thanks!

@samhvcc Congratulations on becoming a new JA30Mk2 owner.
The amps do need a little run in before they can show their full potential, like all new gear. I would also suggest, like the manual states that you don’t listen that carefully until about 1.5 hours of playing time has gone by. The large transformers definitely do need some time to get ’warmed’ up. Nonetheless, the amps sound amazing from turn on...just a little better after the transformers get ’warmed’. Also, after you have lived with your amps for a while, I would highly recommend rolling in some NOS tubes into the 12Ax7 and 12Au7 positions. I just rolled in some NOS Telefunken 12Au7 smooth plates and some NOS Siemens 12AX7’s - this makes for a big upswing in SQ.
As to your question about a 300B amp, I am not understanding your point. The Jadis can deliver up to 45watts/ch...where does 10watt/ch come from?
