Tim Farrant from [Buzz Audio](http://www.buzzaudio.com/) dropped the following info about the new Essence compressor:

_We have the pricing for the 500 Series ESSENCE compressor worked out - it will street for US$875._

_The ESSENCE has a Lundhal 1540 transformer input passively coupled to the OPTO gain reduction element, followed by a high speed Class A make up amplifier and into a Lundahl 1517 output transformer._

_The sidechain design is very similar to our SOC1.1 Stereo Compressor, and offers the same Differential Drive topology. The attack time with this circuit is generally less than 1 millisecond when selected._

_Units should begin shipping in September, due to availability of the Lundahl transformers._

The only downside to these guys is that they're double-wide, but when you think about it, hardly anyone (besides [Adam Jay](https://analogindustries.com/2006/03/500-series-module-porn/)) has a full rack of 500 modules. Every picture I see with a rack has a couple empty holes. So, this kills two birds: you get a compressor, and one of those holes you're never gonna fill gets filled. It's win/win.
