Just a quick thought from my ears here at the BI Test Kitchen ...
Not as mid forward as my gar2520 Not as clean as my gar918 Not quite as warm/thick as my gar1731
garAM10BC... A MUCH more polished lower mid range than any of my other offerings. Should help with mud buildup In a mix. These have a very nice vintage sound about them that will work on lots of sources. It's just yet another audio colour and besides working on 16V rails, its a nice 24v option as well for 51x.
Great, Test kitchen was able to do more testing with comments. I plugged the AM10 into a Litz Wire CAPI VP 25 & 26 Doing a Voiceover on a vintage Walley Heider Neumann U87. Nice solid deep bass and low mids. Not mid forward. Smooth almost slightly compressed. Changed the sound of the CAPIs. A great flavor to an opamp collection.

I am very interested in Gary's DOA too. 2520 and 1731 seem the most common. But what can you guys report about the garAM10 and gar918. Highly interested in those. How do they compare and especially: how do they compare to the 2520/1731
This was buried in another thread. Just for fun I did a quick comparison between op amps. The files are labeled, but I sent a mono stem of drums, guitars, and bass out through a BTA, into the summing amp, and out of the line amp in the box. Each position has an op amp, so each iteration changed all three of the op amps in the signal path. This was all done at low gain, and bipolar 20V (the QE can go up to 28V and the Neumann to 22V). I did retest the QE at 28V and the two files played out of phase nulled completely, so at these gain levels there's not much difference in the voltage.
There’s no summing going on, it’s all mono from end to end. This is like sending a single line input to your console and listening back through the stereo bus.
Q is a Quad Eight style N is a Neumann style G is a GAR2520 (the control)

I have listened to your OpAmp test you just posted. Definitely good samples and very well recorded. But frankly, I couldn't hear any big differences. I never thought that differences were so subtle - it's almost not audible. Crazy.. I am having second thoughts if there really is a need to make use of different DOAs.
The Red dot was for years my favorite, the difference between a well built far equivalent is very very small the biggest thing That Scott’s brings to the table is your eyesight and sanity of not having to build the thing, but building som GARs sure will improve your DIY chops.
