This was quite an astonishing revelation. The Spectral's Tech Lab sounded quite good, and really got the body of the instruments just right. It was almost like I could see the outline of the stand up bass.

But when going to the GCC's volume control, it was just a whole different world. Things were no longer dark (which sounded nice) but suddenly just simply open, with much more detail, and with much less of a sonic signature. In fact, it wasn't till after this test that I realized the Spectral ever had a sonic signature (The Spectral, aside form the volume pots has a custom DC umbilical cord and AC cable for TG labs which was a big upgrade at the time- this Preamp sounded nothing like the thin threadbare stock spectral)

I could not hear what the Spectral was doing all these years, and I realized, yes everything I played has this sonic signature (although it was pleasing)
