Time to Close Down This Circle

[rollo]

  As the former President of Audiosyndrome it is obvious the Club except for a couple of members refuse to use this wonderful forum to talk to each other.
  Time is remove the Circle IMHO as the AS members do NOT appreciate this Circle.

Charles,
Indeed, there's hardly been any activity in this circle for months. Maybe some guys have found a home elsewhere. One of these days, I'll go through the various circles and review for activity and make the appropriate changes. Thanks for bringing it to my attention.

I still like it. Please do not close down this circle! 

Pete (& many others who feel the same way!)

No problem, Pete. I'll keep it open.

Thanks, Nick! I'll also volunteer to moderate it since I am an elected Executive Board member of the Audio Syndrome club.

Merry Christmas,
Pete

I know a lot of club people that are posting on AN all the time. It may not be posts exclusive to AS but they are active nonetheless. A lot of time we may post questions specific to digital, power etc. Knowing that I will post here.

OK so here is a noise issue I am trying to figure out so anyone in AS chime in:

I have 2 dedicated lines for my system.
if I plug my preamp into one and then power amp into the other I get low level noise.
If I plug them both into either line noise goes away.

Ground loop hum, obviously. It's not uncommon. Here's an article with good info:

  Ground issues. The amp and preamp should see the same ground potential. Same receptacle of dedicated line.

Gentleman the request was made since most of our members refuse to post on the Audiosydrome Circle not AN in general. Of course we have members posting elsewhere here but not the point. Look at the posts here. Far and few in between. Meetings of late not posted either. Just feel a perk not appreciated and used much.
Now if it does not bother Nick to keep it fine with me. I will remain Moderator and continue to push use by my fellow club members.

   I would plug Pre and Amp in one dedicated line and the digital in the other. Check it out if not doing now. Both separately conditioned as well.

Not a hum, static, higher frequency. and temporarily removing the ground does not help.

Bob are they saying a potential source is cable tv? Could I find out just by disconnecting the TV leads to the house?
