The Amati Futura adds real bass discipline and full-range authority to Sonus faber's signature warmth. On the used market, it represents one of the discontinued Italian flagships whose acoustic case still holds when examined against the evidence.
The X5 Series 1 delivers 500 watts of controlled flagship drive with an onboard DAC and phono stage. On the used market it remains a credible all-in-one choice for anyone who needs real power without the Series 2 premium.
The first Diamond 25 combined a warm, room-friendly presentation with stage scale and build quality that made it feel significantly underpriced. A used-market buy whose sonic case still holds up.
The TDAI-2170 is built around RoomPerfect room correction in the digital domain — the kind of acoustic control that still puts it ahead of conventional analogue amplifiers even years after introduction. The key question is whether RoomPerfect is the right priority for your system.
The pre-R2R Single Shot is a 200-watt GaN class-D integrated built around transparency and timing rather than warmth. Its DAC has since been replaced by an in-house R2R stage, making this the version that now lives on the used market — and argues its case on sound character, not spec sheet freshness.
The Electra 1008 Be2 is a high-resolution stand-mount that behaves less like a bright beryllium showcase and more like a disciplined monitor. On the used market, its original engineering ambition is available at a fraction of the launch price.
