Feickert Adjust+ Tool

The software does seem interesting, but I am not sure what it offers beyond a standard spectrum analyzer run on a laptop. I guess, part is the excellent test record. The discussion above is great since it may actually give some more insight into this.

A comment on the DMM method: It doesn't work well unless you use a 1KHz bandbass filter for your 1KHz signal (assuming a 1KHz test track). There is too much noise in the background and the DMM integrates the noise over all frequencies. A much better way it to use a Laptop with a spectrum analyzer which allows to detect the 1KHz crosstalk signal directly .

Sonofjim, if your laptop has a microphone input you could just directly connect your phono stage to your laptop.

How familiar are you with using spectrum analyzer? You can use a spectrum analyzer program (like iSpectrum for the Mac) to look at the frequency components of the signal fed into the Mic input. Most spectrum analyzers programs allow you to put a cursor on a frequency peak and display the strength of the signal (in dB). This is a nice way of directly measuring the crosstalk strength from a left channel signal into the right channel and vice versa.

Adjust+ does something similar. It looks at the phase of the crosstalk signal instead - I am right now trying to figure out whether this isn't just possible with the same standard spectrum analyzer. More later...
