The design of the HDA range draws upon all of Arcam’s experience as one of the UK’s most respected audio companies, to produce Arcam’s best performing range of audio products yet – using the best quality components and engineering practices, the HDA range is designed and built to give you years of listening enjoyment.
- Extremely efficient class A/B amplification
- 50W of power per channel
- 5 analogue inputs including phono
- 3 digital inputs
- 32-bit DAC,Sabre ESS9016K2M
- Full I/P control
- Total harmonic distortion + noise = 0.003%
SA10
In any amplifier, the signal path is at the mercy of anything that creates noise within the unit. Thus, we spare no expense in using only the most high-quality components, even if it means the cost of our power supplies overtaking that of everything else.
The result, of course, is worth every penny.
A singer’s sharp intake of breath before hitting the chorus, a guitarist’s fingers sliding against the strings – it’s those seemingly minor details that can bring music to life. Fish out one of your all-time favourite albums and play it through a Bluetooth speaker, and guess what? Its sounds like a Bluetooth speaker. Play it through the SA10, and it’s as close to hearing the artist’s performance as you’re likely to get. There’s always joy in digging out an old recording you haven’t heard in years. With the HDA range, it’ll feel like hearing it forthe first time. |

First Impressions
If youʼre impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression. The subtly curved aluminum/glass resin front panel adds a sophisticated touch that complements any décor. The central porthole display reflects iconic Marantz designs of the past while it brings you an "at a glace” view of the amplifierʼs operating status.
