Hi David if you look at the silk version. You can see a slight roll off. This is due to the hardware, it's not the converters. This is a fairly important part of the sound In my opinion steady roll of after 15khz (subtle but pretty). I know you probably won't get any closer though. If anyone does do a shoot out I would recommend using silk acqua.
The steady roll of is due to the way they compensate the hardware transformer.
yes wobbles or sharp edges in low end don't exist in the hardware. Some may argue its transformer but nothing would ever be that extreme on a piece of hardware unless something was seriously wrong with it! I corrected this in acqua.
this is the old version of silk or is getting pushed?
I think is extremely important to remember that when doing "shoot-outs" between any Nebula/Acqua and an algo plugin, it is one thing to compare eq curves, but a completely different thing if you take into consideration harmonic distortion and other goodies that Nebula/Acqua are very good at. And unfortunately, those are the kinds of things that get over-looked with a quick shoot-out and a few graphs. You are not getting the cumulative effect of having either plugin all over a mix. The free Slick EQ is very good, don't get me wrong. The TDR comp is awesome, the Vladg comps are awesome as well, and everyone knows how nice the Bootsy plugins have been for many years. But a shoot-out like this more likely leads to misconstrued results, in my opinion, if the end results are EQ curve graphs.
