It’s interesting the upgraded Meridian sounds pretty ok to me and I am very picky (I am an audio professional). I only use Stereo mode (but that is my thing, all other processing sounds too processed and disjointed to my ears). There is more than enough low frequencies and the three controls allow to make most high quality source material sound pleasant. it is not the best system I’ve ever heard, but it is definitely in the ok to good range of quality even by my picky standards.
I wonder why some peoples systems sound tinny. Could there be some speakers not working?
