Funny that you ask because way back when I brought up a comment in this thread about what exact product that you used in the article because I wasn't sure which one was the appropriate product to buy once I started researching this on the net.

I had no clue what a DAW was but Google is thy friend and realized I don't have any DAW software at all. The only thing I have that comes close is Wavelab (same folks that have Cubase).

But nice to know this product would work for the headphone EQ despite my confusion on this topic.

After the turn of the year I will put together batches of parts (including the matched transistors.)

In the interim, I'll put together a BOM with the device sizes.

That's great news for those who like a quick turn solution. Obviously I like to go slowwwwwww hahahaha

Great! I dunno when i'll start mine but having the matched transistors is a great start

I am going to have some "carriers" made for the JFETs so that SMT devices can be used. The SOT23 are DGS, but the boards are set up for DSG. At any rate, the carriers will allow the devices to be thermally conjoined.

A miracle for the season!

I even found some old 1k Roderstein resistors that a buddy gave me "way back when" from the audio store where he worked.

I used a DSP hardware product made by Audyssey; EQ Equalizer Pro. DAW software should work also. But I havent tried them. -RNM

I'll certainly be intrested in some parts you make available, especially matched devices.

I'll keep an eye open for updates.

Judging from the Audyssey website, they are pitching the software now. No surprise, as my previous employer pulled out of producing test hardware in favor of software based testing programs.

This seems to be one of their top products -
ARC System 2

Once I purchase the product, I'll be happy to report the steps I took and how well it works with the head amp.

Well, maybe a DAW is needed for the ARC product after all. A reviewer on Amazon.com said it is really a great product but he and many others wish it had a simple plug-in to permit easy playing of one's music library through it.

So it sounds like a few hoops to jump to get to where we want to be. I'll keep searching for a similar product that may be more 'plug 'n play'.
