Did you have the $7 cedar rings under the Crown? That makes quite an improvement on the depth. That was the first thing that I noticed when I tried it.
Paul ,What is there to disagree with , the Crown is not a balanced line amplifier.....
That might be it, I need to get some of those cedar rings, thanks OzarkTom . I sure hope Jackman has some . ZAK
Zak, if you're real bold you'll tell me what diode that is under the two screws. D901
Do you have to unscrew it or is the number on the outside. ZAK
It would be under the plate, held on by screws.
Agreed. My point is that I believe a properly balanced impedance input stage, fed by a balanced impedance output source offers substantial benefits, especially when you've a component that's leaking currents onto the safety ground.Would somebody with a ZLS please [unplug the amp from the mains and] measure the resistance between the safety ground prong on the mains inlet and the outer signal ground on one of RCA sockets and post the value? If there is no continuity, that would be great. TIA
Pin 1 would be what to measure the XLR to safety ground on IEC jack, middle leg. (Pin 1 is connected to chassis)It appears this is a source for that noise as Paul predicted as possible. There's a circuit to safety/chassis ground. Where? Good question because if it's prior certain parts it'll also create a rise in induction. That's pretty textbook, so I'd like to think not but you'd also think there wouldn't be the continuity you just found.
How about pin 1 to a chassis screw? And screw to RCA ground? (Outside)
Hi Guy,I've been playing with the Crown throughout the day. Will provide a detailed update and comparison tomorrow. I wanted to give it a chance to warm up and make sure my subs were dialed in properly. For starters, I'm always amazed by how compact and lightweight these little Class D amps are...and the Crown is no exception. It weighs almost nothing, runs cool and silent in my system. No issues with fan noise and setup was a breeze. No matter how it compares to the NCore or more expensive amps, I'll probably pick up an XLS, especially if I find a 1500 for under $200. It is very compact and does not lack for power. Very impressive little amp so far...little in size only, not performance. PS - if I get one, the binding posts will have to go, unless i just make a set of Speakon speaker cables.
