Hi. I just found this forum by searching information about Dynaudio's studio monitors and I have already read some of the topics where has been discussion of BM5A and BM15. Great discussion going on here! I had Mackie HR626's and liked them very much but had to sell them because I was moving to a room which was not very good for monitoring (walls like paper) so I have been monitoring only with Sennheiser HD650 headphones. However now I am moving to a new place where I can use monitors again so I need new monitors. I produce electronic dance music (trance) and I need a good and accurate bass response and clear highs with good stereo image and separation (don't we all! ) . It seems that the Dynaudios could give that to me. I guess there's no place near where I could listen to these speakers so I have to ask you guys here. So... 1. Can the BM15 passive sound as good as the BM15 active? Do they sound the same or are they still different speakers? I don't need to play very loud. 85-95dB at max. I want to know if the passive version could bring me the same detailed and accurate sound as the active? I haven't heard the actives either but read much of them from here and there. 2. Does the BM15 passive sound better than the new BM5A? What might the differences be in addition to the BM15's better bass response? So which do you think is better? How much lower/better does BM15 play the bass than BM5A? 3. The BM15 has a very big bass driver. Does it still play transients well? I need a good bass frequency and transient response that I can mix my kicks and basslines well. I have no plans to add a sub later so that's the reason why I am leaning towards the BM15 passive. 4. Can you suggest a cheap and still good power amplifier to use with the BM15 passives? I don't need huge powers but at least 50W per channel. It can be a hifi- or studio model. 5. Has somebody listened to both BM15 and HR626 and what were the differences? Any info/experiences about BM15 passives, amplifiers and BM5A's is highly appreciated!
