I neglected to mention in my above report on my last visit to the Bunker, that Mark sent me off with an obscenely generous amount of Nuclear. Unlike Mark, I don't like to add STB piecemeal, so I went home with the stuff before evaluating the result. Accoutrements included painting Nuclear on some of the existing patches around the internet equipment and on the amplifier. The television power chord was already 2/3 covered in an earlier model of STB, so I covered the entire length with Nuclear without removing the older material. I also covered the length of the untreated desktop monitor power cord.
When I turned on the music, I discovered a top end, which I didn't realise was missing until I heard it! Nothing else was compromised as a result: only improved. I then thought I'd open the back of the speakers to see if I could add some STB inside. That proved too difficult due to the compact size of my speakers, so I replaced the backs having only managed to place two small strips on the inside of the rear cowling. However, I tested the screws securing the speaker cones to the front of the speaker housing and they were somewhat loose. I tightened them all, and powered up the system. Wham Bam, thank you Ma'am! It was as if the floodgates on all the STB enhancements I had made up to now were opened. The improvement was huge! It's as if the speakers tripled in size. Suddenly I had a sound stage: something which a mini-system isn't supposed to have. I won't go into all the detail, but believe me, EVERYTHING was improved. Thereafter, I covered the entire top of the amplifier with Nuclear, and the sound has just gone from incredible to more than incredible with improvement to detail, realism and airiness. The best Christmas present I had this year!
I highly recommend to anyone with speakers which are more than a year old, and in which the cones are secured to the cabinet with screws, that they check them for firmness. You will need a technician's toolkit for atypical screw heads.
