Dob- OP is asking for comparison btwn LS100 and LA-150. The Joule LA-300 is in a different league price and quality wise. It would only be fair to compare it to the Dan Wright's more expensive (LS 36.5??) two piece unit. I've owned both the LS 100 and either the LA-100 or 150 (not at the same time). I'd say that the Modwright is a value leader that is very neutral and perhaps closer to a ss sound. The Joule tended to be a bit slower, fuller, more tubey sound and was good at conveying emotional impact. If I wanted to add a tube sound to a system w ss power amp I'd probably pick a Joule product. If I had a tube amp and wanted to stay w tubes while maintaining speed and neutrality (whatever that means) I'd go w the Modwright. but you need to compare statement or near statement pieces to each other, not basic to statement. My $0.02, YMMV.
