minidsp have an easy to use userinterface, and the amp delivers a good full bodied sound with lots of details. It's not very powerfull, but ideal for small speakers or speakers with high efficiency
i was thinking of this mother board ASUS E45M1-I DELUXE or the pro the pro is cheaper but it sayes that i can only use singel channel ram is that right
Just to be clear...
Direct Digital does not drive a speaker with a digital signal. But it does amplify a direct digital input. This technology takes the digital PCM signal and converts it to a Pulse Width Modulation. This PWM signal is then amplified and then demodulated to drive a speaker.
With that said, there are several chips on the market right now with PWM amplifiers that drive machinery directly from the PWM wave form. This can, in theory, be translated to driving a speaker with a digital wave form.
Which PWM Technique is Best Part 4
In most cases this direct digital format is at the mercy of the switching speed of the FETs, the clock rate, and the quality of the power supply (read: 65dB PSSR of the MiniDSP circuit).
This is why we (Core Audio Technology) put so much emphasis on power supply and clocking for digital technologies. Lower bandwidth power supplies would just be at the mercy of quantization error and amplitude distortion.
If you want to build your own direct digital amps you can play with MiniDSP or design something for yourself using the TI chips based on their EVM. But you get what you pay for there.
Enjoy.

the problem with ti is the software etc like kjeldsen writes
and the minidsp 200usd one i can well opgrade the power supply on that right and i can buy the software
