Naim’s Sales Director Doug Graham talks on Naim’s Statement pre and power amps. Presented by av2day.com video.
By Lam Seng Fatt After the Kojo Technology Crystal Ep virtual grounding plugs improved the sound when fixed to the black terminals of my ATC speakers, I tried the third plug with RCA cap on my preamp. I couldn't find any unused RCA input in my streamer/transport, DAC or power amp, so I had to use the tube Lamm LL2 Deluxe preamp for the test.
By Lam Seng Fatt Kenix Chua of Begins Acoustic gave me the opportunity to try grounding speakers when she handed me three Kojo Technology Crystal Ep virtual grounding plugs on the last day of the Kuala Lumpur International AV Show last weekend. Two of them had spades while the third had an RCA plug. I was told to plug them into the black terminals of the speakers or an unused black RCA jack of the preamp, DAC or streamer.
