It took almost 2 hours for me to set it up. I was so worried if I would accidently damage the stylus. I hope some of the instructions were better written, but as said by others it wasn't too bad. The tonearm setup wasn't that bad either.
The first record I played (Dvorak's Cello Concerto, Rostrovich, Karajan, Berlin Phil) sound much more musical than Thorens. Deeper base, wider sound stage, and more details. Also, highs are more clear. However, it was still somehow muddy and congested in full orchestration (well, the comparison is to a $30,000 system that I had a chance to listen to about 6 months ago). Thorens was much worse on this.
For some Jazz album I tried, the difference was even bigger. I thought my Thorens/Grado Gold was pretty good in handling horns, percussions, and voices, but Bluemotion sounds much more lively. More punch base, more forthcoming horns. I haven't tried much on voices yet.
Bluemotion is also much more susceptible to sound vibration on high volumne than Thorens. The two tables sit side by side on top of a two shelf audio rack. I am not using any tweak or isolation devices. Footfalls near the table are still heard, but Bluemotions' minimum-suspension design seems to work better than Thorens (which I think is a suspension TT) on the wood floor.
I am using Clearaudio microbasic preamp. Overall, I guess the money well spent. The only catch so far is the color. I thought I would like the blue color, but it actually is very dark bule. A slightly lighter blue might have been better for me.
