I've been searching for a long time for a quality Mastering Buss Compressor. I am satisfied my search is over. The SPL IRON looks and most of all sounds Excellent. Tightens and glues everything together very nicely indeed. I also use it on individual instruments too. Great on warming up Bass Guitar mixes.
Must Have Vari-Mu
Was not expecting that much out of this, but definitely became my favorite plug on my stereo bus. Just dropping it on at the end is enough a lot of the time to give the last bit of punch and glue.
Invisible-compression chameleon. Love it.

This one stands out.......Nice iron quality to the sound, not brittle but smooth. Distinctive distortion when pushing. This company is reaching deeper into what I like to hear with this sound. Thank you so much for this wonderful plugin, and the great deal!
Great sounding compressor, but...
I really like the sound of this compressor, especially with Germanium 1mF; however, I strongly dislike the incremental input and output at steps of 2dB. I understand this is a reflection of hardware, but the plugin version could use extra continuous input and output knobs. This is a particular problem during mastering where I need complete control of the input and output levels and not be tied to these increments. 2dBs is HUGE in the context of mastering. I need 0.1dB increments or better. Again, great sounding compressor otherwise.
this thing is so fat it's obese! not only is it a great mastering/buss comp, in which it excels, it makes a fabulous tool for fattening up kick/bass/sub&synth tracks and is equally gorgeous on higher frequency content, such as ac guitars, overheads e.t.c, haven't tried it on vocals yet but i'm pretty sure it would excel there too. i dare to say it actually sounds very 'organic', it can go from subtle to squash (where it never sounds harsh) has a broad range of attack & release settings and with the incredibly useful bx additions like tmt modelling, m/s mode, monomaker, stereo width and parallel mix, it becomes a truly dynamic powerhouse. i would suggest checking out the manual to get the very best out of it. if i weren't a subscriber, this would be very, very high up on my wishlist. nice job bx.

Well, what an addition top my UAD Shadow Hills + UAD Manley Vari-Mu collection! It has lots of controls (read the manual to take full control over the plugin), but it is absolutely easy to operate and it doesn't take much time to dial in beautiful sound. It's both smooth and tonally rich, I'm pairing it with UAD Manley MassivePassive for my current tracks and this is just wow. Get it!

SPL Iron is huge
by T. W. Tobin
After using this for mastering compression on a recent EP project, all I can say is wow. This thing sounds huge. I was choosing between UAD SSL G, TDR Kotelnikov and SPL Iron. All are excellent in their own way, but I ultimately chose Iron because it seemed to add some additional weight and warmth. I need to spend more time with it to full appreciate the vast amount of controls and flexibility it has, but so far I am loving it.
Well, it's now my go to bus or master compressor, it can do everything, and I like that you can fine tune the sound with the Eq settings, tape emulations,... Must have in your sonic arsenal !
Truly gorgeous sound and soundstage. And It's ALMOST there with the GUI.
I have many high end compressor plugins so it's really hard to impress me, and IRON did without a single doubt. You can go from very subtle super glue to very audible pumping to everything else in between while being able to dial in as much character as you'd like. It's truly a beast. In addition to groups and the mix buss I sometimes also use it on individual instruments. Improvements? Yes, there are two that are VERY much needed to make it five stars. It's frustrating to have them in a plugin as high end and otherwise versatile as this. 1. Give finer control over the input and output gain. With all due respect, 2dB increments simply isn't a good design for something intended for high precision mastering. This needs to be remedied -- it should be .5 dB increments at the very most. 2. Also, do away with the +, 0, - switch for the input and output gain knobs, and just give us a single dial that goes in either direction. The less mouse clicks the better, always. This needs to be remedied, too.
