Hi I have the dynaudio audience 70, which is driven by densen beat 100 and that is linked to my audiolab 8200cd via MF X10D tube buffer. I like the sound, but am looking at an upgrade. I am interested in the rotel 1580/1582 pre-power, because living in Singapore, it cost in local currency the same as naim nait xs (an amp that i am also interested in). In terms of pounds, the 1580/1582 is around 2,000 pounds while the XS is 1,500 pounds, so would I get more bang for buck with the rotel pair, which is also more powerful? How is the rotel-dynaudio pairing? Would I be foolish to deviate from the synergy of densen & dynaudio? Otherwise, should i consider the densen beat 130? The beat 130 costs the same in local currency as the rotel and naim but I cant seem to find reviews or user experiences. I listen to mostly rock.... Thanks in advance!
