I heard Duevel Bella Luna Diamantés recently in Paris (hifi-video) but just in the main shop as I hadn’t booked a demo. The amplification was on the cheap side (1/10th cost of the speakers and it showed with a rather hard sound but they did show promise. I was more interested in the Sirius but there wasn’t one there to hear. The guy in the shop said the Sirius needed at least a 60 square metre room to work in and my new place will have i living room of around 50 sq metres, he suggested I also consider German Physiks HRS-130, I could stretch to borderlands if there was an advantage in that. I’m after a large scale sound for symphonic music but don’t want ten foot guitars when playing a bit of folk or rock and the Bella Lunas scaled very well to the recording.
My amplification is Naim 500 series so should have no trouble driving them but I do wonder if it’s a good sonic match to GP, it’s certainly an unusual one and I’ve not found any dealers who overlap in France or the UK but then there aren’t very many GP dealers in either. There are a couple of positive reviews using lower end Naim with Duevel Bella Lunas.
