The SA-1B5 is a 1:1 sounding replica of the legendary Danish Opto 1B compressor in a 500 series format.


The SA-1B5 has been a popular request for many years. Many companies have attempted to recreate the CL-1B's beautiful and articulate top end as well as its peculiar time constants without success...until now. The SA-1B5 sounds EXACTLY like an original CL-1B compressor with some added modern features and for the first time in a 500 series format.

Featuring a custom US-made input transformer, a custom Lundahl output transformer, hand selected tubes and a proprietary custom made opto element exclusive to Stam Audio, this unit not only has the same frequency response and tone but also the same attack and release times as the legendary Scandinavian compressor at a fraction of the price.
