K.333, 475, and 457. Fine playing and very realistic sound on this SACD box set on the Iso-Mike label. From their site: "IsoMike™ (Isolated Microphones) is an experimental acoustic baffle system, to address the interference of intrachannel sounds that results in compromised fidelity. For these 4-channel recordings, the microphones were suspended on four arms, separated by IsoMike™ baffles. Most baffles absorb sound from mid- to high-range frequencies; lower frequencies are more difficult to absorb. Here, the unique shapes of the IsoMike™ baffles are advantageous. As lower frequencies flow around the heart- or egg-shaped baffles, they are scattered, effectively dissipating their energy. Eliminating line-of-sight between the microphones seems to lower some fidelity robbing cancellations, this reveals a layer of extreme detail and a sense of increased sensitivity. As such we took great care, therefore, to reduce the noise level within the auditorium during the recordings."
It looks a little funky, but it certainly produces great results!
This is too minimalist for my taste--I should have known better since I detest minimalism. I've read so many glowing reviews...yes, the playing and sound are great, but for me, it's much ado about nothing. Qobuz makes it easy to remove from one's library!
Sibelius: Symphonies 1-7 with Okko Kamu and the Lahti SO on BIS SACD in Mch. Excellent interpretations, excellent sound, though even lower in level than most BIS discs, which are known for that. I just need to turn it up more.
