S is for "Super"
- this brand new amplifier may look like the standard DIA-250 amplifier we introduced three years ago, but in fact we put more than a years work into improve every part of the DIA-250s already fantastic award winning performance. We changed and improved the electrical circuits and layouts in more than twenty ways, the most significant being:
- Optimized mains filter
- Improved general and local power supplies
- New input stage
- Improved output stage
- New analogue stages in the D/A converter
- Improved digital signal routing
- Updated firmware
- Improved connectors
- Incorporated aptX Bluetooth module
More details, better micro dynamics and more "air" around the performing musicians. Everything is served with naturalness and a musicality normally reserved big expensive class A/B amplifiers - the result is stunning!
