Many devices will not like a 640R load and will produce more distortion than they would when unloaded. A typical input impedance for an...

FrenchFan, 2pA/Hz^.5 is the current noise of OPA1612, which needs to be included in the account.

Hi horias2000 Your measurements are good. The problem is that you did not consider the input resistance of the Scaler (100Kohms)...

Here is a working SPICE model for the OPA1633 if you still need it.

I recommend replacing the 220u/10V capacitors with 470uF/16V (C1 C2 on my schematic). I personally use 1000u/16v, I get much better LF...

@trl When you want to know if the ODAC has issues with the low load simply use the Motu and put a 1k resistor in parallel to (both)...

HpW, you did ask me in PM about MONO/STEREO, and I replied: The slider in Cosmos tweak app is only for MONO/STEREO switching. To send...

@IVX: When overdriving the Cosmos ADC - don't the opamps in the differential input stage drive quite heavily into the input protection...

Interesting Interesting Interesting So, if I understand correctly, for a standard E1DA Cosmos user, we could set the E1DA to 1.7...

Interesting idea. I wonder if that could be applied to REW and if that would be a benefit for typical noise testing.

I posted that txt in Audacity forum/feature request: The Cascaded ADC is a well-known technique used for 40 years or so in industrial...

Please use English on ASR.

Very glad to see the responses to your post have been quite civil and explanatory in nature this far :) Welcome to ASR. And yeah, my...

I am happy to read reviews of 'old' products, since it gives us an historical context that we can use in order to judge current product...

I am. If you have a pre-amp after it, that is how you use it.
