You have to listen to yourself, to be able to form a judgment. After reading the reviews, I bought my unit, to test it with my Philips 37PFL7605 with its sound, I was really happy so far.

Finally I have to the outstanding image quality of Philips TV to adequate Sound.Das device is optimally designed so that adjustments to the timbre not necessary. With little things, like the separate switching on and off, you can live. Only a visual indication of the volume level would be desirable. Conclusion: In Your Face!
