Congrats FLD for a job well done.
IMHO this room just blew me away! Room 624 was a venue that I spent a lot of time in.
First observation would be the silence and blackness of the room. Its the Purist cables that I was hearing (or not hearing). This is what the cables are supposed to do. The music appears from the background.
Next would be The Accuphase Digital Separates. At USD 33,000 for the pair, I knew its not for the ordinary man. The sound was just right. Not bright, nor warm, not even neutral. I could say its balanced! That's the term.
The symposium Isis rack was my dream rack but I don't recommend it for use with a turntable.
Last but not the least were the Harbeth HL5's. Truly a world class speaker.
