I know the forum is not really devoted to the inexperienced and I understand. It might be painful to explain everything in the basic details all the time. But since Iím interested in building an M2x I have to ask:

What does this really add? By your description I understand that this is a preamp to the M2x, making it an integrated amplifier i.e. I can connect a 2V signal directly to it. Is that correct or the Melbourne is in fact one more alternative to the other ones already offered, just a different sound signature?

Will it give you a means of volume control as well?

Different sound signature - classic Aksa harmonic profile (look at FFT spectrum in post 1) of moderately low distortion with predominantly 2nd harmonic and descending higher orders. Plus it has gain so that you don’t need a separate preamp. There will be a new motherboard that holds these DB’s so that you have a stand-alone preamp.

There will be volume control on the new MB. On the M2X as DB, no volume control.

Hi xrk.

The Lender and the Melbourne are both built as pre-amps?

Can you explain the sound difference between the Lender and the Melbourne version for people like me that don't know what you have said, and don't know the difference?

Is the Melbourne more accurate, and how much difference?

If we use the Melbourne for the ACA Class A amp, is the method of running the ACA from it similar by changing resistors?

Still waiting for the Mundorfs here.

Melbourne is same sound signature as Aksa Lender - it just can drive a lower impedance load. Plus had ability to be DC coupled on the output.
