Greetings, If your Sony is a digital receiver chances are more than likely that there is something magnetic in the turntable and you need to purchase a small preamp to boost your sound. I had a similar problem when I hooked up my older Dual to my new Yamaha digital receiver. I could not figure out why the sound (volume) was so weak. I'd turn up the receiver all of the way and still very moderate to low volume. I purchased a small preamp thru that other greeedy auction site (wont say it hear, rhymes with decay) for about $10 added it on and boom, rocked the world.
