Awaiting a 1st impression

It kind of boils down to this: for a very similar price, would I buy a PL or an Aesthetix Mimas (also tube hybrid integrated)?  The answer is clear: Aesthetix.

In their adverts Upscale makes a point of how much their preamps weigh as compared to the competition.  I've heard of judging by the measurements, but even ASR doesn't say that heavier units are intrinsically better.
