Paolo, I pulled 5 shots and picked the best video (the first would you believe!) but they are coming out rather nice. Bit hard to tell if the diff between the lusso and the QM, but the espresso is much more to my liking straight up, and not as strong in a latte. Might be down to the beans though. I'm going to fire up the lusso in the next few days before I box it up and do a taste comparison. Anyone want to help? I got the dose much better, and better distribution in the basket, and I've been anal about tamp level. It's all come together. Now I need a decent tamper (Still waiting on Jack's replacement one). Regarding the pump noise, I think it's a combination of a few things. Firstly the drip tray top rattles if it's not pushed all the way back, and secondly I think the safely valve is touching the case. I'm not that worried about it, if the drip tray is pushed in properly it's not that bad, and only runs now and again. When I get time I'll be taking the case off to just have a look and while I'm there I'll take a look at the pump noise issue.
