Product Description
Product Description
The Mission 778X blends vintage aesthetics with modern audio performance, delivering 65W of powerful, refined sound in a compact, retro-inspired design. Ideal for both vinyl lovers and digital streamers, it features Bluetooth, RCA line, coaxial, and digital inputs. Its integrated phono stage is optimized for MM cartridges, providing precise sound without the need for an external pre-amp.
Experience enhanced precision and musicality with the Wharfedale Diamond 12.3 floorstanding speakers, the more compact option from the DIAMOND 12 series. This speaker maintains the same accuracy and refinement as its standmount counterparts, making it a perfect, affordable choice for 2-channel hi-fi systems or as part of a high-quality home theatre setup.
Mission 778X 65W Integrated Amplifier with Phono & Bluetooth
The Mission 778X is phono-ready with a JFET-based phono stage that provides precise RIAA equalisation, optimized for MM cartridges, so no extra pre-amp is needed. It features RCA line, digital, and coax connections, alongside a Bluetooth receiver with aptX/AAC for CD-level audio streaming from smart devices, offering both convenience and high-quality sound.
This amplifier is equipped with a high-performance ESS ES9018K2M Reference chip, utilizing ESS Technology’s 32-bit HyperStream architecture and Time Domain Jitter Eliminator. This allows for ultra-low noise digital audio file compatibility, with sampling rates up to 384kHz (PCM) and DSD256.
The headphone stage matches the performance of standalone headphone amplifiers, delivering dynamic, detailed sound thanks to its high slew rate design. All around, the 778X provides engaging and refined performance, catering to modern music enthusiasts while honoring Mission’s rich heritage.
Wharfedale Diamond 12.3 Floorstanding Speakers (Pair)
The more compact of the Wharfedale DIAMOND 12 series floorstanding options, the DIAMOND 12.3 loses none of the accuracy and musicality of the standmount (bookshelf) options. With enhanced presence and power, the DIAMOND 12.3 is refined and the perfect, affordable floorstanding speaker for 2-channel hi-fi systems, or as the front pair of a seriously impressive home theatre system.
Configured in a 2.5 way system with exception crossover technology, the DIAMOND 12.3 utilises dual 130mm (5”) KlarityTM drivers for impactful yet refined mid-range and bass frequencies, while the 25mm (1”) dome tweeter delivers open and smoothly extended high frequencies.
