Want to purchase something I can move around the house/chuck in a suitcase when i go on holiday etc. Best one I think I've seen so far is the Sony SRS-X55. Is there anything else that would be better in terms of sound quality? A big bonus for the Sony for me was the fact it had an actual sub where as others in this range don't seem to. This makes a big difference for me as I enjoy lots of bassy music
