I spoke yesterday with the guy I did the domo for, and he said that the smile is still on his face...
He has two sets of Amplification.
A set of two mono blocks, made by an Israeli firm, and an H2O.
We tried it first with the moco blocks, as they were his favorites.
But there was a problem. There was no Spec on the web site or anywhere, about the Amp's DF!
We called the maker, to find out the missing data. He claimed they do not know, as it never been measured because it is insignificant and doesn't matter.
Unfortunately for him' it was after my cables were hooked. So the DF vs Cable's resistance were proven already.
The conversation was ended with a look saying all and we switched to the H2O (DF=1,600). It stayed there till the end of the Demo.
It is so bizarre, that people (so called Audiophiles), tend to argue a subject, they know nothing about, never tried it and still do it. Why?
