That's interesting you like the phone correction SW.
I was going to demo that but they don't have the calibration file for phones I'm using here.

I could use an inexpensive spare set, I'm almost tempted to get the software+Superlux HD681 to check it out.

It is a bit of a disadvantage that they don't have other cal files available for some of the more popular phones. I would think it would help increase sales. I did see somewhere that shipping for a bundle w/phones was around $30 to the US. It looks like they are located in Riga, Latvia. That's way out there from where I am...
 
I think I will send them an email requesting some other default cal files.
 
I would like to see this take off and gain a sizable customer base. It is possible it could change the entire thought process about mixing on Phones. It would be so cool to be able to carry your mixing reference around wherever you go.

Regarding ARC mics - they will work, however we can't be sure of the results. I'd say, they'll be good enough to have a taste of what the software can do, but there's bound to be some variation - especially in the highs.
 
When we ordered our batch of mics from the OEM, we had to individually calibrate them in an anechoic chamber against an ANSI certified mic (Earthworks). The usual sample-to-sample variation in frequencies over 7k was up to 3dB.
 
As for calibrating other headphones - shoot us an e-mail and we'll keep your request in mind. Once we get enough we'll order some headphones to measure. In a week or so we expect to get a large batch to measure.

Tried the discount code for the software only regularly priced at $69 but it doesn't take it.  I'm also curious about this but they don't have my KNS8400 headphones on file.  I'm also reluctant to ship them out to Latvia!  The concept sounds great but their list of headphones is fairly sparse at the moment.  I did find an average curve for these but you have to send in a text file of the curve (i.e. frequency, level, frequency, level, etc.) and they generate the file for you.  All of this just seems complicated and more akin to a science project!

I understand your doubts about sending your headphones abroad, we are looking into getting an agent in US to do the measuring.
 
It is good that you mentioned what your headphones are, we already have had a few requests for KNS8400, so we'll surely make an effort to acquire a few samples to measure them.
 
As for average curves - we usually generate them by measuring a number of samples from the same model, to account for FR spec spread. You can send in a curve, however we can't be sure how accurate it is. The problem is that currently there are no set standards for measuring headphone FR and everyone does it according to their understanding. I can send you message once we get a KNS8400 average curve out.

The discount code applies only to the $49 Trial + Mic deal here...

http://storeus.sonarworks...mac-xref-20-microphone

So it looks like if you want to purchase the Sonarworks Reference 2.2 (for Windows) + Mic it costs $299.00.
 
If you order the Trial $49 + discount and just the Sonarworks Reference 2.2 (for Windows) software $219.00 it could save a few dollars. Or do I have that wrong???

That sounds about right.
The software download is $216.00  & the kit with Discount/ shipping is 54.50.
Total $273.50 instead of $299.99 (plus shipping)
Windows upgrade to 3 from 2.2 is free, correct?
I'm certain it is but want to make sure before ordering.

I did see that the 2.2 -> 3.0 upgrade was free and maybe available end of 1st qtr. I am seriously considering this also if it will provide me an alternative to ARC or ARC2.
 
When I first setup ARC I really liked it but something is different about ARC2 that I find less pleasing and it no longer fits my workflow using multiple monitors as you can no longer use different speaker correction files in multiple instances of ARC2. I agree with your thoughts in post #2.

Yup, no man gets left behind!
 
As for the trial + download version price difference, that's right as well. It isn't easy to be sure about the benefits of our software, so we try make it as easy as we can for you to try it out.

I ordered a Dayton Audio EMM-6 ($40 on Amazon). At their site, you can enter the serial number and download that specific mic's calibration file:

When it arrives, I'll download the Sonarworks software demo and give it a try. This seems to be the simplest way to try this and some other software I've been looking at.
