We listened before installing spikes. With Audio Research 330M monoblocks for amplification, we began with the same track with which the 330Ms dazzled me at AXPONA 2025, Rimsky-Korsakov’s Danse Macabre from the classic Minnesota Orchestra collection Mephisto & Co. (16.44.1 FLAC download, Reference Recordings). Then we turned to a newer but not necessarily better high-resolution recording, of Thomas Adès’s The Exterminating Angel Symphony (24/96 FLAC, Pentatone/download) performed by the Minnesota Orchestra under Thomas Søndergård.Then we installed the spikes under the preamp box and listened again. Highs were a bit more brilliant and tighter, the presentation even more alive, dynamic, and resolved. The spikes also delivered more transparency and textural clarity and further highlighted the Audio Research 330M’s luscious and colorful midrange. My customary component supports, Wilson Audio Pedestals, may have delivered highs that were a bit smoother, but CH’s spikes showcased the L10 at its best
