G7Trader. Your source is the problem. No matter what speakers you have they are going to sound flat and boring with poor quality streaming sources. I run a pair of Beovox S60's from a Beomaster 1900 fed by Beogram 2402, Beogram CD-4500, and Beocord 1900. This setup with quality source recordings is nearly unbeatable. I can make this statement with 100% confidence because I also own plenty of other top quality systems, the Beovox will step up and punch it out with the best of them.
Bang & olufsen is no good, sound quality is poor I've also owned many beomasters and beocenters.
Since this post I upgraded my amp from Rotel RX-602 to a Rotel RX-802 which has a lot more power then I brought a Pioneer SA-9500 II and wow that is an amazing amp.
I since went to my local B&O shop and heard the Beolab 90 which cost £58,000 my Pioneer is very close up there.
I also since brought a dual cs 505-1 record player but my Amazon fire stick youtube via TV still is a better sounding source.
My next purchase will be Pioneer Spec 2 & Yamaha NS-1000.
I also have all the parts for the BBC LS3/5A speaker which I am self building see my other post.
I have the Kef Concerto, the Beovox S75 sounds a lot better.
