I am looking for a complete set of speakers and am pretty decided on the Monitor Audio range. For fronts, I have listened to the Silver 8i's and the Gold Reference 20's. On films, I couldn't tell a lot of difference but on music, there was a definite difference - bass was much deeper and clearer on the Golds. Mind you at £1500 a pair, I guess I should notice a difference. Any owners out there have for and againsts for the Silvers or Golds. Are the Golds really twice the speaker of the Silvers? The Centre speaker is less of a problem, I will probably match whatever front speakers I go with. The surrounds are the real confusing issue - the Silver FXi's , the Gold FXs or full range floor standers / bookshelfs (Silver 5i's). Even though I have had demos of dipoles, I am not really sure about whether I am convinced about the difused sound they put out. I am after a 7.1 set-up so whatever I go for, there should be 4 rears - perhaps full range central rears (Silver 3/4/5i's) with dipole/bipole sides (Silver FXis or Gold FXs)? Anyone got the Silver or gold rears and how do they compare? Bearing in mind that the golds are twice the price of the Silvers, how did any Gold owners justify the extra expense and did you go for the Golds all round? BTW, the room size will either be 17x12 or 20x17 feet. Thanks all as usual for opinions and advice.
