Removing DC is important. I’m calling it more important that most people are aware of.
It is certainly a very good sound improver regardless of the usual talk about hum in transformers. The benefit is so radical even if transformer issues have been noticed.
On this forum, a person tried to put an Isotek Syncro cable before a PS Audio power plant (which includes dc-blocker). He said it improved the sound coming out of the regenerator.
Most people have 1-1,5 v of dc on the line (sometimes more).
The most common tech to get rid of dc is dc-diodes (like a light) that starts to consume dc when the dc current is strong enough, usually 0,7v. This leaves all dc below 0,7v still untreated.
Other tech like IsoTek Syncro rebalances the sinewave but “my guess” is that that is just another way of describing diodes that consumes dc above 0,7 v thereby leaving a lot of dc to lower Audio performance.
Have anyone tried to put more than one DC-blocking equipment before the stereo? (If so, was it better than using just one dc-blocker)
Are anyone familiar with the different dc-blocking tech and can advise on how to get rid of all dc? (In a way suitable for high end audio)
Looking forward to learning more…
