Impedance mismatch... (BD-Design)

Hi Dmitry,

The CrazyA's have +100k input impedance and the CrazyV is less "transforming" impedances making it a rather good passive combination with full bandwidth in that setup (CrazyT > CrazyV > CrazyA) and short interconnects.

I once measured the output on my amps using the TD+ and a Django and compared that to the CrazyV...with the Django the high frequencies already were -3dB at 20kHz (limiting bandwidth) where the CrazyV is still at 0db at that frequency.

Using a low output impedance device and this bandwidth limitation did not occur...

This directly results in less quality bass too (more wooly, less dynamical and less "drive"), much less a problem with the CrazyV...

I am not much of a real technician to go much deeper in theory but I guess this explains a bit anyhow...
