Hi Corey: Nope, never heard of this, but I bet it works well for film or tape. I have my doubts about grooved disks because a lot of the most annoying stuff there is pops and ticks, although reduced background whoosh is a good thing, too. -- Tom Fine ----- Original Message ----- From: "Corey Bailey" <[log in to unmask]> To: <[log in to unmask]> Sent: Thursday, December 22, 2011 2:30 AM Subject: Re: [ARSCLIST] Straight Line Tracking was Stanton Turntable reviews....anyone? > Hi Tom, > > Might you be referring to a process known here on the Left coast as "Swamping"? > > This is a process where a mono signal is bussed to two channels.
