Never heard of the real thing.

It is very easy to use and is useful.

One of the best dynamics processors I own

I LOVE this compressor and use it on everything. Really shines on vocal dialogue because of how clean & transparent it is. The warming harmonics are subtle and beautiful. Auto settings across the board plus feed-forward give this thing some serious flexibility and ease of use.

Thank you Elysia.

Tökéletes mixre és utókeverésre. Kihozza a zene dinamikáját és ízlésesen adagolhatók az arányok. Csak ajánlani tudom.
Köszönöm Elysia.

I feel like I've stolen a $10,000 compressor

Plus the MS for widening control is amazing, and the soft limiting is perfect. My favourite plugin rn.

Nice addition for soft limiting

Use this to slightly limit my kicks. does a trick I just can't exactly explain, but it works.

Big and clean sound

Realy good for dynamic M/S processing on my Mix Bus. It’s big and clean.

Super clean and still unique

I passed over this compressor for years because I didn't know the name, ended up buying it in a bundle based on the customer reviews. The first time (and every other time) I used the compressor I quickly found a clear, big, pop-master tone that has eluded me for years. Fantastic.

Today it is my favorite mastering plugin.

Today it is my favorite mastering plugin. Great sound, which I often use in various tracks, including on the new M.D.E.N. album. This plugin was widely used!

Once you find out how to use it you end up having it in every mix. Not only on the master, but on the drum bus as well. I now have 42 UAD-plugins and this one is one of my favourites.

This plug-in changed my life!

Wow, I own well over 100 plug-ins on the UAD platform and this is the first time I have felt the need to go back and remaster finished tracks. What a difference, what control I have now. It is now so easy to get tracks hitting between -9 and -8 LUFS like the labels want while retaining the openness, clarity and punch the artists that I produce come to me for. This compressor is so versatile it can replace many of the plugs that I use. If you are new to the platform I highly recommend this as one of your first purchases. I even think I can save a poor mix at the mastering stage with the alpha on my side. This plug-in sounds expen$ive!

Corrupts Delay Compensation in PT

Consistently corrupts the delay compensation in my PT sessions. Pretty disappointed in UAD's lack of resolution to this issue after all of the money I've invested into using their hardware and software.

If you know what this is.... You know what you saved!!!!

Man this was one of the first plugs I demoed at a friends studio. It’s completely amazing. The speed and clarity of this plugin is really flattering to any track.
