Can I use the speakers with this amplifier?, Speakers from broken Micro Hi-Fi System Options

[larswes]

My Philips MCM7 amplifier is broken (bought it 5-6 years ago).
But i think the speakers from the system is still ok.
I consider to buy a new amplifier for the speakers and i found this compact design Dynavoice D-amp.

Do you think this could be a good combination, for music and tv or other source?

From the MCM7 specs:

• Output Power [of my broken amplifier]:
2 x 50 watts RMS, 100 watts total power
• Main speakers [still ok]:
3-Way Bass Reflex
6 ohm impedance
6.5" aluminium con woofer, 2" Tweeter

Dynavoice D-amp

Specifications:
Nominal Power Output (Left & Right Channel (4Ω): 25W + 25W
Nominal Load Impedance (8Ω): 15W + 15W
Main channel: 4Ω - 8Ω
Input Sensitivity: 300 mV
Overload source emf: ≥2V
Frequency Response: 20 Hz – 20 kHz
THD: ≤1%
S/N: ≥95dB
Channel separating degree: ≥70dB

Thanks for advise. I will consider this compact type of amp. I will continue googling for similar alternatives. Found this much cheaper (more powerful?) but ugly design: http://www.tradera.com/12-v-forstarkare-mi...70613_166584511

With a PSU that cannot deliver more than 24 watts? That's likely not more powerful. If I were you, I would check the 2nd-hand classifieds. True, capacitors don't always live forever, and the volume controls will wear, but you can get very reasonable two-channel amps for cheap.

Good point. Even if we grant 100% efficiency to the class D amplifier, it nets out to no more than 12 actual real world WPC. This is over 6 dB less than the original electronics package (50 wpc) which represents a potentially significant loss of audio.
