The 778X is an integrated amplifier by MISSION that delivers 45 watts x 2 channels into 8 ohms and 65 watts x 2 channels into 4 ohms. It was released in December 2022. It is a 2-channel design using a Class A/B output stage. It has a built-in DAC (ESS Sabre32 ES9018K2M Reference), so you can play digital sources directly with no separate DAC unit needed. It also has a phono input, so a turntable can connect straight to it. The MISSION 778X has an MSRP of $549.
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The MISSION 778X is rated at 45 watts RMS into 8-ohms. MISSION provides this wattage at a THD (Total Harmonic Distortion) of 0.005% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 45 watts into 8-ohms (20 Hz-20 kHz) at 0.005%
- 65 watts into 4-ohms

Which speakers suit the MISSION 778X?
45 W into 8 ohms, 65 W into 4.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
MISSION 778X is rated at 45 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the MISSION 778X with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
Inputs and Outputs
Besides the performance specs of the MISSION 778X, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
MISSION 778X features built-in Bluetooth 5.0 for wireless music streaming from your Bluetooth-enabled devices such as Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows PC, Mac computers/laptops.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
MISSION 778X supports the following Bluetooth Codecs when used with supported devices:
Phono Input
MISSION 778X features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
DAC and Digital Music
The MISSION 778X's built-in DAC allows the connection of digital sources directly, eliminating the need for an external DAC. The DAC chip that is used in the 778X is the
ESS Sabre32 ES9018K2M Reference, and supports resolutions up to
32-bit, 384KHZ.
MISSION 778X Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓45 watts per channel into 8 ohms, 65 into 4.
- ✓Distortion is specified at 0.005%, an order of magnitude below what is generally held to be audible.
- ✓Built-in DAC handling 32-bit / 384 and DSD, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Phono stage built in (MM), so a turntable needs no separate preamplifier.
- ✓Bluetooth (version 5.0 and aptX, AAC) for playing straight from a phone.
- ✗The phono stage is moving-magnet only; a moving-coil cartridge would need a step-up or an external stage.

How much power does the MISSION 778X have?
The MISSION 778X delivers 45 watts x 2 channels into 8 ohms and 65 watts x 2 channels into 4 ohms. It increases its output into 4 ohms, so it has some headroom for harder-to-drive speakers.
Does the MISSION 778X use vacuum tubes?
No. The MISSION 778X is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the MISSION 778X?
The MISSION 778X uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the MISSION 778X have a built-in DAC?
Yes. The MISSION 778X has a built-in DAC (ESS Sabre32 ES9018K2M Reference), so you can feed it a digital source directly without buying a separate converter.
Can I connect a turntable to the MISSION 778X?
Yes. The MISSION 778X has a built-in phono stage for MM cartridges, so a turntable can be connected directly without a separate phono preamp. It is voiced for moving-magnet cartridges; a moving-coil cartridge would need an extra step-up stage.
Does the MISSION 778X have Bluetooth?
Yes. The MISSION 778X supports Bluetooth (Bluetooth 5.0 and the aptX, AAC codec), so you can stream straight from a phone, tablet or laptop.
How much does the MISSION 778X cost?
The MISSION 778X has a manufacturer's list price (MSRP) of $549.
