hi, new here so excuse any repeated requests. anyway, i've just taken receipt of my toshiba 36zp18q tv and 220 dvd. i have old (but lovely) mission 753 speakers as my hi-fi and part of my simple pro-logic system. now i'be got the new tv i need to consider an av amp for digital sound. my budget is £300-£400 max. it needs to be quite powerful (not sure how much though) and quite musical, probably a tall order on my budget. richer sounds seem to be doing alot of deals around the £300.00 mark, are any of these any good ie. sony, nakamichi, denon. i really don't know how powerful an amp i need to ensure my front speakers are ok with hi-fi too. cheers for any info..
