First, the gear... Pro-Ject Xtension 9 Hana MC low output cart Prima Luna Dialogue HP Integrated Marantz 6006 CD player Manley Chinook phono stage. I am now using a Parasound as a loaner. Shunyata power conditioner, power cables and outlets I got most of my gear within the last three months. I occasionally get a popping sound out of my speakers when my table is engaged. By "engaged" I mean when the AUX 2 (my table input) is selected on my amp. It happens regardless of whether or not I'm playing an album. It does not happen when I play a CD. Originally I thought it was the Manley, because it didn't happen when I played CDs. So I spent $80 to send it back to Manley for a checkup, and got a Parasound loaner phono stage. The issue is still happens with the Parasound. Here's what I tried to isolate the problem... - Switched inputs on the amp. Didn't resolve the issue - Took my table, and the cables, to a HiFi shop and tried it out on their gear. The popping did not happen at the shop - Tried a different table at my house. The popping did not happen with the different table (it is a low end Rega) - Borrowed a set of $300 cables (as opposed to my cheap amazon cables), to go from the out on the Parasound to the in on the Prima Luna. Did not resolve the issue I'm at a loss. The popping doesn't happen with the Rega at my house, but it doesn't happen at the HiFi shop with the Pro Ject. Am I missing something?
