MIT T2 cables added clarity, but colored the high frequency range- too bright for me. The Audioquest Type 4 were a revelation. Think of the difference between a 1980's CD and the same CD remastered today. With the Audioquest cables, music became transparent, but without any added brightness.

This is a review of Audioquest CV4 2.5M (8') with 48V DBS. Prior to using these cables, I had DH Labs Q10 as well as Belkin PureAv PCOCC cable. The CV4 DBS cables are of star quad design, which provides low inductance without spiking the capacitance. The conductors are solid core, said to provide smoother, more natural sound.
