Nope, TobWen, that's not reality. I never recorded anything with a bobbin and caps. Reality check is using a low ouput ribbon. As I said the Onyx 800R was very low noise with a ribbon. You shouldn't use the low impedance settings that they recommend for ribbons - that's real BS.
Short circuit trick in my vocabulary is shorting pins 2 and 3. That's often done, and you can produce EIN figures of up to about -134 dBm that way. A 150 or 200 ohms resistor is okay and produces results that pretty much correlate to the real world.
The datasheet of the NJM2068 has nothing to do with EIN! It's equivalent INPUT noise. The opamps are not at the input. The input stage is the two 2SA1316 transistors. And as I said those are ultra low Rbb types. In transformerless preamps EIN can be predicted by Rbb of the input transistors. The opamps do contribute to output noise, but output noise is usually masked by input noise, at least at higher gain settings.
As I said: the onyx performs as spec'd. Don't go on insisting the specs are bad. It's simply not true. Don't make false claims if you don't know what EIN is or how it is measured.
The EIN figure you claim is very bad. -120 dB would already be less than good. -110 dB is almost unusable. If you want the realest of real world test, use an SM58 connect it to your Onyx and connect it to any other preamp for comparison. I'm pretty sure you won't find a preamp that's noticeably lower noise.
