PAD Rev A vs. Rev B

I believe the mix of metals in the wire were changed from A to B. The B is certainly better, but not the gain that occurred when the original Colossus was upgraded to Rev A.

The revisions continue to refine tonal balance as well as tightening up the bass frequencies. The latest Colossus has terrific bass impact, but without the excessive bloom the first version had.

Hi,
I did ask this question to PAD sometime ago about their cables and what they replied was that apart from no difference in the looks, the Rev A was more hifi sounding while the Rev B was more musical and correct sounding! Apart from this, the Rev B is more extended than the Rev A especially in the upper regions and to a certain extent the lower regions! As such, if you have both side by side, you might feel that the Rev B is slightly more brighter while the Rev A slightly more warmer sounding but actually it is just revealing more! I've compared both the Colossus ic's and I find both give the details but I slightly prefer the Rev A as I find it a bit more warmer! Hope this helps!
Rgds,

The Rev.B is a big sonic improvement over the old Rev.A.
