What is high impedance Transparent Audio cable for ?

Hi,
       In their Reference MM2 line, we have to choose between high or low impedance cables.
In what application do we need the high impedance one ? tube > SS, or SS > tube or tube > tube ?
                                                                   Thanks

It used to be simple as most valves had a high output impedance and most solid state had a lower output impedance.  That is not true anymore.  The best answer is to call Transparent or email and we will let you know if the cable will work with your electronic component with the current calibration.  The match creates an openess and dynamic ability that is not there without the proper matching.  The setting is mostly determined by the source end of the cable.  I hope this helps.

 You got it form the horse's mouth :) but when I ordered my Ref XL MM2, I specified the 2 components it was going to connect. The box came labelled that way as well. If you changed components, you could send the cable back to them for "retuning" (or whatever they call it). Do they not do this anymore?

Thanks,
       BradO, I will connect from my Esoteric D03 which has output impedance of 100 ohm. to ARC tube preamp with input z of 120Kohm.
and also from this ARC preamp with 600 ohm output Z to MOON solidstate which has 90Kohm input Z balanced. I guess I will have to
use Hi Z for both cables. from what Transparent told me.

Gandur,
             thanks, I think the specific matching is not avail in " basic" Reference model. problem is  TR recommended Hi-Z cable
for source with ouput Z of 100 ohm or more. And my Esoteric DAC has output Z exactly at 100. it's the highest recommended for
Low-Z cable and lowest recommended for Hi-Z cable.  What a tought decision to make.
