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

“Specifications:

These Dynavoice D-amp Specifications are from the:

And
http://www.tradera.com/12-v-forstarkare-mi...70613_166584511
is another amplifier.

And
“* Specifikationer:
* Output Power: 180W + 180W
* RMS Power Output: 30W
* Peak Maximum Power Output (PMPO): 180W
* Input Power: 12V 6A DC”
How can an amplifier fed by a “12V 6A DC” (i.e. 72 VA) power supply, be “Output Power: 180W + 180W” (360 W!)?

“* Min. THD: <0.005%”
“Min. THD: <0.005%” is an absurdity as an amp’s THD characteristic. Then MAX THD may be 10%, or more?..

And between THD “≤1%” and “<0.005%” (200 times difference between two very similar devices), do you believe it’s realist? Which of the two may be real?

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

Why do you wish to buy a 13 V amplifier? Or I’ve misunderstood something? A 13 V amplifier for a home system?
With “THD: ≤1%”? To me, strange for a modern transistor amp.

Why not to buy one of well-known ≈50 W/channel 220 V 50 Hz integrated amplifiers, with a remote control and developed features? And 100 times better THD… There are very moderately priced ones rating 0,01-0,02% THD 20…20000 Hz on the market…

As I said "now i know more" and that was what I was after when i posted here. I will try to find something not to expensive to replace the Philips amp.

Why not to buy one of well-known ≈50 W/channel 220 V 50 Hz integrated amplifiers, with a remote control and developed features?

So far i've not found any amp with these spec within my budget. But i found a piece with RMS 2 * 25 W / 220 V that maybe can be ok?

In this aspect, what would you say about these budget ones:

YAMAHA A-S300:
Minimum RMS output power
(8 Ω, 20 Hz to 20 kHz, 0.019% THD)
[A-S300] ................................................................ 60 W + 60 W
(6 Ω, 20 Hz to 20 kHz, 0.038% THD) [Except for Asia model]
[A-S300] ................................................................ 70 W + 70 W
6 inputs, a “Phones” output. Has no monitoring function.

or
NAD C316BEE: Continuous output power 40W/channel; 0,01% THD 20 Hz-20 kHz. 7 inputs, a “Phones” output. Has no monitoring function.

(there is Swedish manual on the page too).
or
NAD C326BEE: Continuous output power >50W/channel; <0,009 % THD 20 Hz-20 kHz. 7 inputs, a “Phones” output. Some more expensive, but has the monitoring function.
