Digital-terminator 75 Ohm

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

I am doing some easy tweaks to my Marantz SA-7S1. One of them is terminating the coax and BNC jacks as well as adding the ground wire and copper ring around the ac male plug.

All of the above helps to lower the noise floor thus better detail etc.

One of the tweaks I am having a hard time with and I think I am correct. When adding the terminator to the coax the sound stage tightens up, bass is much better defined and the things become more laid back, thus a perceived smaller sound stage.

Yet at times is seems like the highs are rolling though drums and high hats strikes sound more like the real thing with great body. I keep going back and forth on this one tweak.

If I recall when the noise floor lowers their will be a perceived loss of high due to the noise being part of the reproduction as well as a more natural sound stage that may seem like a loss of detail due to listening to noise in the past.

I like the terminator in due to the much more realistic presentation top to bottom, but it takes some getting used to.

It would be helpful to me. I am sure while speaking with Chang Light Speed many years ago he noted to not get fooled with detail that is noise and you will think the highs are rolled even though they are not, just the extra detail you have been used to hearing is gone.

Anyone bother to comment?

Yes, a little RF noise causes increased perception of 'detail.' - Al Sekela 11:19:02 02/20/09 (5)
