So who makes the grooved disk EQ you guys are using that makes the phase corrections? Is that phase issue now a phantom menace? -- Tom Fine ----- Original Message ----- From: "Doug Pomeroy" <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, May 12, 2015 10:23 AM Subject: Re: [ARSCLIST] Playing Edison Diamond discs > Tom, > > Just for the record, I like analog, but I use EQ in the digital domain all the time (in it's > analog version, > which includes phase correction). > > I find the accuracy and repeatability of computer based EQ a positive benefit.
