Well sir, the data is from 12 years ago;right about the time I abandoned the direct in approach. The data is from my personal experience. The cd player at the time was the Sony 707esd, a very fine unit I might add. The amplifiers were ARC tube units. The wire was MIT MI-330 E.
From memory, I recall 2 cds where enough gain could not be achieved.
1)William Boughton/ English String Orchestra/Music of Gerald Finzi/ Nimbus Records
2)Dire Straits-
Brothers in Arms
There were others, which is why I abandoned the direct in approach.
Say, I thought this was a discussion forum for people to help each other out. I am starting to get the impression that its a members only fraternity. I see I have been slammed on this thread. Perhaps my experience was an isolated case. Apologies if I was wrong
