I compared it playing with over 10 cds repeatly with the JM Lab 707 speaker. To summarize it, JM Lab is like a glass of sugar water (very bright with strong emphasis in high freq.) The Piano Home is like a glass of pure water - excellent transparency and sound stage. Songs playing from it doesn't make you tire easily. You can also catch more details from each song.
However, if you are into Rock and heavy metal - this is not the choice. Play Norah Jones' blue or Jazz or classical and it really flys. Pop vocal is also very comfortable on ears. Also, you can turn on the volume really really loud without losing details - this a very important point about this speaker because of the resanance control is very very good. Only a few expensive speaker can do that well.
I do believe the Utopia line of JM lab could be better but may just a nose or so.
Also, I find the review below very accurately describe the charateristic of this speaker.
