This trial was actually done at the same day when I tried DEMAGNITIZER
at my friend office Mr. CB, you can read the description on the following
link http://www.sap.or.id/Demag_B&W_803_Eng.html
But I want to describe this GC-8 trial in this individual page in order
to be more focus
Mr. CB's system is relatively simple and consist only on 4 equipment
as follows :
Source
: MacBook Pro 2010
DAC
: Chord Qutest
Integrated Power Amp : Gryphon Diablo 300
Speaker
: B&W 803
Date of Trial
: May 29th 2019
Description about GC-8 connection to Mr. CB's system can be found on
the pic bellow
We did step by step connection from GC-8 to Mr.CB's system one by one,
starting from Chord Qutest DAC, Gryphon Diablo 300, BW 803 and finally to
MacBook Pro.
We noiced that, every connection from GC-8 to equipment in Mr. CB's
system always bring certain difference level of sound quality improvement,
but the best one achieved by connecting GC-8 to Quitest DAC and MacBook
Pro, followed by connecting GC-8 to Gryphon Diablo 300 and B&W803.
Because there are few channel left on GC-8, Mr. CB decided to make 2
connection from Quitest DAC to GC-8, as can be seen on configuration picture
above.
Before we connected GC-8 to MacBook Pro I was assuming that this connection
would not give any improvement in sound quality, because The MacBook Pro
connected to Quitest DAC, via toslink input .terminal
Digital optical connection are very well known of having excelent immunity
again any noise and interference. But after connecting done we were so suprised
to hear that there were still sound quality improvement can be achieved
by connection GC-8 to MacBook.
I assume that, although optical cable have very good immunity again
noise, we must remember that before converted into optical signal,
digital signal are previously in the form of electric signal that
can be attacked by noise or inteference in many way, one of them
is through digital ground track
