The Rialto 600 is an integrated amplifier with built-in DAC by AudioControl that delivers 100 watts x 2 channels into 8 ohms and 200 watts x 2 channels into 4 ohms. It was released in 2015. It is a 2-channel design using a Class D output stage. Bridged to mono it delivers 400 watts into 8 ohms in bridged mono mode, which is the usual way to use a pair of these on a demanding speaker. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It has a built-in DAC (24-bit/192kHz Wolfson), so you can play digital sources directly with no separate DAC unit needed. The AudioControl Rialto 600 has an MSRP of $899.
There are 2 AudioControl amplifiers in our database. Below you can see the main specs of these amps.
AudioControl Integrated Amplifier Series
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 AudioControl Rialto 600 is rated at 100 watts RMS into 8-ohms. AudioControl provides this wattage at a THD (Total Harmonic Distortion) of 0.09% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 100 watts into 8-ohms (20 Hz-20 kHz) at 0.09%
- 200 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 96dB Signal to Noise Ratio

Which speakers suit the AudioControl Rialto 600?
100 W into 8 ohms, 200 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
AudioControl Rialto 600 is rated at 100 watts into 8 ohms, which puts it in our 91 to 120 watts band. The next band up is 121 to 180 watts, which is worth about 1.5dB 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. Plenty of systems are better served by the 61 to 90 watts band and better speakers.
When pairing the AudioControl Rialto 600 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.
What size of room is the AudioControl Rialto 600 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the AudioControl Rialto 600 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Poor |
| Small Room | Poor |
| Mid-size Room | Good |
| Large Room | Good |
| Very Large Room | Average |
Inputs and Outputs
Besides the performance specs of the AudioControl Rialto 600, the next important feature set that you have to evaluate is the input and output selections that it offers.

Bluetooth Connectivity
AudioControl Rialto 600 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your AudioControl Rialto 600. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
AudioControl Rialto 600 doesn't have a phono input so in order to play your vinyl albums, AudioControl Rialto 600 has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Subwoofer Output
AudioControl Rialto 600 has a dedicated subwoofer output which can be used to connect it directly to a powered subwoofer via an LFE(Low Frequency Effects) cable.
Check our
Powered Subwoofers page to find a subwoofer that will work with AudioControl Rialto 600 amp and your speakers.
DAC and Digital Music
The AudioControl Rialto 600'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 Rialto 600 is the
24-bit/192kHz Wolfson, and supports resolutions up to
24-bit, 192KHZ.
AudioControl Rialto 600 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Power nearly doubles into a harder load, 100 watts into 8 ohms rising to 200 into 4, which points to a power supply with real current in reserve.
- ✓Class D output stage, so it runs cool and wastes little power as heat - which is how it fits in a small case.
- ✓Built-in DAC handling 24-bit / 192, so a TV, computer or streamer can connect digitally with nothing in between.
- ✓Digital inputs cover 2 optical and 2 coaxial.
- ✓Pre-outs (Sub, Bridged Mono) leave room to add a power amplifier or an active subwoofer later.
- ✓Headphone output (3.5mm).
- ✓At 218mm wide it fits where a full-size component will not.
- ✓5-year parts warranty, longer than most of the market.
- ✓Detachable mains lead (IEC 2-prong).
- ✗Only 1 analogue input, so a second source means unplugging the first.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
