I have two pairs of Large Advents with refurbished drivers. Find them to sound very colored and closed-in. I remember loving friends' Advents back in the day, so I am disappointed. Listened to them with a variety of top vintage monster receivers, Marantz 2325, Sansui G9000, Pioneer 1050, and Kenwood KR-9600. FWIW.
Another suggestion, better at jazz than rock, is the EPI 100s. Inexpensive, easily sourced on the used market, replacement/upgraded drivers and crossovers immediately available via humanspeakers.com, and excellent sound quality at lower volume.
