I have a Ypsilon Aelius mK2 mono power amps, Ypsilon active pst100 pre, Ypsilon VPS 100 Phono pre, couple Ypsilon SUT(large and small), Techdas Af2 turntable, Graham Phantom Elite tonearms, many cartridges, Ansuz Ceramic Speaker cables, 4 Ansuz Ceramic Power Cords, one Ansuz ceramic interconnect(sut to phono), and 2 Stage3 Gorgon Interconnects. Private electiricity line for every Ypsilon equipment. My room 7 meter X 9 meter.
I listened Raidho D1.1 in my system. All I can say is wow. Unbelievable sound stage, 3d images, clarity, definition, transparency, musicality all are exceptional. D-1.1 bettered Rockport Avior in every way(of course Avior play powerfull and more in bass area). By my experience I can clearly say, D1.1 is worth every penny and I cannot think any audiophile think D1.1 is not a exceptional speaker. Maybe it not suits you, but it is damnn good speaker.
I did not listened other raidho's in my system, but i demoed and listened them in many occasions. They did not give me the same impression. Were they good, were they performed well, yes. But I never had an idea about their potential, until listened in my home.
So, I dont know why so many raidho's for sale, but if you are looking for a really good speaker, and if their in your price range, give yourself a chance to have one(not give chance to raidho, i dont think they need it).
