MixChecker from Audified is on sale for $99 until this Friday.  I just bought it, and I'm giving it a test drive.  I'm always looking for anything to help my mixes.  Check it out: https://shop.audified.com/blogs/news/mixchecker-save-50
 
P.S.- In spite of the date (Feb. 7), I got an e-mail from them today saying it was good til Friday.

Let us know what you think, Lynn!

So far, so good.  It's simulations are similar to ARC 2, but has some new ones that I like, such as earbuds, headphones, Auratones, and a few others.  All  these simulations have taught me to trust my own speakers more, but they do help get results quicker.  I'm curious to hear what others say.

OK, I ran MixChecker through its paces today, and here are my observations.  I have an old pair of Auratones (ca. 1979) and the simulation in MC is spot on, much like the one in my VRM box.  The tablet, smartphone, and ear buds are realistic compared to my own items.  All the other  simulations are good, and, at least equivalent to the ones in ARC 2.  It has a MONO button which comes in very handy, as well as volume compensation.  At this point, I'm glad I picked it up.  Hopefully, it will still be on sale through tomorrow.

$ 50 is reasonable, but I decided to buy.
They fell to $ 75.  50% sale
