Francisco, I'm truly skeptical one can transplant someone else's system fully into a new space, and hope for an identical outcome.
Ask Ked. His take on MikeL's sound is that it's a finely balanced synergy of gear interaction, room dynamics. Mike's personality is writ large in the resultant sound. Do we really believe Mike's system would sound remotely as good in Ron's more challenging space?
My take on The General's sound is that it's part and parcel of his exemplary space, and his DNA runs thru his system.
Hi no, systems like Mike's are based on room, tweaks, and many things other than the components itself. In the case of G's system, if anything, room is a weak link. It is big, but there is nothing else in the room that says good acoustics. His system is great because he has able to quickly cut through BS to identify the best driver, how to drive it (Mayer 46, unlike people trying SETs on apogee or Krell or class D on horns), the best LT with a cart that sounds bad in may set ups but here contributes to the best analog you will hear. Having heard the system with Mayer 211, NAT Magma, and Audio consulting, Etsuro Cobalt, an MSL Platinum, Vyger phono, all of which can be fine amps in some other systems, it is quite apparent why Ron said copy it. Even swapping valves on the preamp can cause a quick downgrade.
I think the key reason for this is having such good music and records he has excellent listening points and frankly if you stick to the basics of look out for what is good on piano, violin, then orchestra and jazz, you can't go wrong. His listening and system build comes out of simplifying rather than complicating.
As I told Ron today while he was putting ice in his English breakfast tea (yes he does that), just as our listening experience evolves from pre panels and post panels, pre analog and post analogue, and pre horns and post horns, there is pre listening to G's system and post. And then when you get some of the recordings and use them for audition, you will be able to cut through so much audiophile BS.
So yes, with a decent room size, the system can be copied. You will need some of those recordings though. And preference and costs aside, many horn systems can be copied. If you copy Tang's system, you will get a similar sound provided you have a decent size. But if you copy an excellent Dagostino - cone/planar system, room will play lots of issues.
