The most natural sound in the world.

Yes, Goebel Divin Noblesse speakers.

Actually my room is quite terrible with a lot of challenges.

My system is all about extreme grounding, mechanical isolation, and great electrical parameters.

Charles,

       I will record again for further improvement in tone and texture. Lot of changes.

Thanks Alex. I ordered the Nils Lofgren cd today, as I don’t have a server.  I will record it in the future and post it.

Regarding grounding I’m only here to express my personal experience. Yes, grounding for me is more profound than room acoustics. The removal of noise from the system completely changed the way a loudspeaker interacts with the room. Not here to argue with anyone regarding this subject. This is my experience from listening to some of the best systems around the world.

Yes, room acoustics are very important. Grounding is even more critical, makes or breaks the experience for me. Results will vary for some depending on the complexity of their grounding scheme. 
 

Order of importance from my experience.

1- Grounding  

2- AC ( most AC filters suck the life of the music)

3- Mechanical isolation 

4- than room ( do not get the first three correct, no music even if the room is great)

I will get a lot of heat for my statement, but hearing is believing.

The most natural reproduce sound in the world part II.

Getting rid of artificial brightness and warmth.

Thanks Alex. Working on part 4

The Nils Lofgren live recording is very compromised in my system.

I can record if you like.
