I've had the Little Loco for about a year now. It replaced a Parasound JC-3. The cart is the new Benz Micro Wood SL and the difference with the LL is not subtle. First, the soundstage is much more delineated and solid. Some records I have that exhibited some slight sibilance are now clean. The LL loads the cart completely different and it shows in the tracing prowess. It can sound a bit dark at times but inner detail is still very clear and the most interesting thing I heard was if I hadn't played any records for a few days/week, one can clearly hear the suspension loosen up and settle in as the first record is being tracked.
My only regret in buying the LL is that I didn't swing the scratch for the Phono Loco. Can only imagine how much better it is as the LL is a giant slayer.
