Hi, there is a small chance that they may have used mk.1 cables (these are very thin, without the triangle symbol on the plugs). If this has happened, the only problem you are likely to have is that the Beolab 3 speakers may give a humming or buzzing noise that can be heard over the music.
If you do experience these problems, I would suggest asking the store to change the cables for you. Otherwise, there is no need to worry, as the quality of the wiring in the cables is the same for each version of Powerlink cables.
If you do decide to change the cables at any point, you may wish to bear in mind that there are other brands of cables available for your Beolab 3 speakers with very high quality wiring and gold connectors, which you can either purchase yourself, or through your B&O store.
Kind regards,
Steve.
