Hi Cougar4U,
So sorry, I had a senior moment,a decade earlier than I should. It was the cord on the preamp that I changed from 14SE to ac-14XL. The A21 still had the AC9 SE. What was amazing to me was that the combination of the pre (Benchmark Dac2 HGC) with the new power cord completely altered my system for the better. The thing is that the Benchmark is hardly what you would call "dark sounding", although it is incredibly smooth and refined. Even so, replacing the Benchmark's cord with the Pangea 9XL made a huge improvement in the sound exactly in those areas that I thought the amp was lacking compared to my previous one. The only explanation I have is that the A21 is very sensitive to component quality upstream.
