I buy this system base on previous review for a client who be look for something a little more than just a vanilla setup . I like the idea of ARC technology which allow both the Sony Bravia tv and the bdv-f7 to simplify the control of the system through the `` HDMI Control '' feature . once the system be hook up it seem to work well , however as I be train the client , I notice the input on the bdv-f7 would not switch properly when the client change the input on she tv . the issue get worse and finally stop work altogether . I be currently work with tech support to determine a solution . in addition to the switching issue , the client also complain that the sound be muddy and muted sound . sound be virtually inaudible at the mid volume mark and push the volume close to max result in a awful blaring effect . I have my own a\/v business for three year and be quite capable with troubleshoot issue like these but I simply could not improve the sound . the sound quality be simply unacceptable . ultimately these problem would have severely damage my reputation have I not insist on place customer service above all else and be completely honest with the client . I have spend far too long work on this job . chalk it up to my fault for not return the item at the first sign of any issue . I be 100 % disappoint by this product . it be now up to Sony 's customer service to pull a rabbit out of its hat . something which likely will not happen give the widespread lack of customer service most company exhibit these day . my advice to you potential buyer be : go ahead and purchase the unit . if you see a problem right off the bat , return the item . Crutchfield -lrb- which be where the item be originally purchase -rrb- should not , in any way , be to blame for the poor review of this product .
