Many of my friends said the original diablo sounded clean, powerful but dry, insipid and flat. The zen sig and the idsd sig (blue one) give a more substance and layer into the sound

Ok, interesting! I find the Diablo to definitely be clean and powerful sounding, but I like the tone and sense of space a lot, so it's interesting people hear it differently. It makes my headphones sing and not just planars - dynamics, too.

But it is good to know that they found the Zen Can Signature to be some more substance and layered. That's what I was looking for.

I never felt (heard that of the OG Diablo or the 2) for that matter, although I perceived the 2 to be a bit less on the "analog" side than the OG I think that almost all of our products steer towards the side of "old school analog" type sound that I dearly love!

More or less TBH part of the reason I fell in love with iFi gear from the start.

Cheers, and trust your own ears!!
