Magnepan 1.7i speakers with custom GR-Research crossovers, all 5n silver internal wiring, and WBT-0710-AG pure silver binding posts. Crossover, wiring, and speaker binding post upgrades doubled the sound quality of the maggies. the capabilities of these legendary speakers are nowhere near their potential from the factory with their very thin tinned wiring, magnetic binding posts, and budget crossover parts. Upgrade those parts. Maggies are on Magnarisers on solid marble stands with brass footers. Townshend super tweeters on custom stands with anti-vibration pads provide extreme holographic detail to the 12,000-100,000Hz frequencies.
