Wonderful! What is the recording you are playing?So, yesterday I compared the GM70 you heard in Bill's system the Kondo Neiro 2a3 in the Living Voice Air Scout system I posted about earlier, where I had compared the Audio Note Empress Silver 2a3. As you can see from the below video, totally different sound to the one you hear in Bill's video. This is only a 15 x 12 room.
In Bill's video you heard the Graphite tube, here we preferred the Copper tube. We still have to try the copper at Bill's.
