Well my friend..all i have to say about the 8.1 will be good things..I was introduce in real hifi world after listening the 8.1..up til now i am still wondering how on earth could such little pair of stand mounters sound so confident..The 8.1 produce such a depth of low frequency that i swear someone must have hide a subwoofer somewhere..the sound stage were so expansive an huge. Frankly speaking their sound doesn’t match their size.
.i have own diamond 9.1 and now the bx 2..none of these have never been able to produce the depth of sound..even my old 9.1 when accompanied by the Subwoofer SW150 across dm38 was not a match..even at party level they remain composed and yes they did shake the upper floor ..the midrange are also very airy with depth to vocals..they only complain i have is.8.1 could have done better with more sparkle in the treble department..my friend had it across an Cambride audio pre amp and power amp..i am yet to ask her for the model number of these so that i can be more specific..
