I think most of us in the forum have been following UltraAnalogue for a while along with the changes they have made to his recording chain. Just the other day I noticed they posted some new music samples from the latest tapes. It is now clear they have achieved a level that any other company would swoon over. The improvements in the recording chain has apparently made the chain invisible. Nothing added or subtracted but real just like you are in the room. Now I don't mean the same "In the room sound" like regular recording but now actually in the room. No electronic sound or emphasis at any level. With all of the silver in his recording and playback chain, that could be part of the reason. Listening to the Audio Note system with all silver I got the same sound listening to all the silver while Charlie/King was playing his Stellavox into the system. Noting in my 45 years of listening got to that natural level.
For us old people remember when you went to a movie and you could always spot the special effects? Now they are invisible just like the UltraAnalogue sound. No person buying tapes from Ed Pong ever has to worry about "HiFi Sound" and now he has surpassed anything he has done. Whatever improvements he made to the recording chain you can hear it clearly in the sample and the reels should blow any buyer away.
