Philharmonic BMR monitor powered with a Hegel H95 or H 360, depending which room I move them to. They were a DIY kit from Meniscus Audio. In Baltic Birch cabs. I used top tier Clarity caps for the tweeter, air core inductors and mid tier Clarity caps for the midrange circuit and all Mundorf resistors. Much better x-over components than most speaker companies use. These speakers are transparent and accurate. Solo piano sounds wonderful. Violins sound realistic. Being a stand mount, they don't scale as large as a full orchestra, but tone and timbre wise, they're excellent. The speaker designer is a professional classical violinist. The best I've ever owned, they make my other speakers sound sad. DIY rocks!
