Classic optical compression with an even faster release

The SA-2A earned its reputation of being the closest sounding replica in the market to an original 1960’s LA-2A. With many companies coming out with an affordable LA-2A clone we decided it was time to step up our game and take it to the next level. While we were proud of the first SA-2A and still think they are great sounding machines, we knew there was something missing aesthetically and that we could add functionality without changing our original replica. The SA-2A+ is identical to its predecessor but adds a second T4B option with a faster release, the pre-emphasis pot on the faceplate, the original VU meter and a 3U faceplate with the original knobs.


The SA-2A+ is built with premium components

We have gone to great length to faithfully reproduce the compression characteristics and tonality of the original. It features a Sowter input transformer (UTC A-10 replica) and a custom Altran output transformer that precisely match the ratios and frequency response of the original UTC transformers as well as an increased level handling capacity. The NOS 6AQ5 tube used in the SA-2A+ surpass the compression capability of any other replacement used by mass production manufacturers. We have made no compromise in parts which ensures you are getting the best sounding compression possible. All our units are hand made and calibrated in our workshop in Chile where they get a full health check twice and burn for 24 hours.

While plugins have come a long way and are incredibly useful, there’s a reason the top engineers still have analog gear in their racks.
To give your recordings the warmth, depth and power you hear in all your favorite recordings, you need hardware. The SA-2A+ gives you all these things in spades. Stunning on vocals. Amazing on bass. In fact, most things will sound better by just running them through the SA-2A+ circuitry without even compressing!

    The original SA-2A was my first Stam Audio purchase, I was looking to add some outboard to my recording chain in order to improve the signal going into the DAW whilst tracking, rather than using plug-ins after the A/D conversion.

    Being based in the UK, I was nervous ordering having only read a few reviews and comments on web forums, But I spoke with Joshua on the phone and was lucky enough to be able to order a rare ‘in-stock’ unit.

    It arrived promptly, and incredibly well packaged. I did have to pay UK customs charges on it which was a drag, but even so it was still a bargain, the build quality is exceptional.

    Without doubt no other single piece of equipment has had such a noticeable effect on my recordings. It was a night and day difference. I honestly couldn’t believe the improvement. Vocal tracks now sounded much smoother and thicker, bass tracks just locked in place and sounded richer and warmer. In fact I haven’t found a single instrument that doesn’t benefit from being run through the unit.

    And it is just so damn enjoyable to use.

    My only problem now is that I liked it so much that I also ordered the SA-76-Rev-A, so now I have to decide which one to use as they both sound exceptional, of course when appropriate my favourite setting is to use them both in sequence!

    I can only imagine that the SA-2A+ is going to please anyone who orders it. Having the extra options will be a great benefit, although I like the limitations of having just the two controls (plus the toggle) on the original model.

    If you are considering a purchase, I say just do it. may take a while to arrive but once you start using it you will be smiling every time.
