Schipo, if you knew Himiguel, you would not mock him. I had no interest in the BMC PureDAC as I thought it was really only of use to those using headphones, which I cannot stand.
I once had Lowther full range driver speakers. I was told that Lowthers can take six years to sound their best! I sold them before I got to that point.
I have also noticed that the four levels of High Fidelity cables take longer and longer to breakin. The best take at least a month to reach their best.
