TEST OF FM ACOUSTICS FM 300A POWER AMPLIFIER (CLONE)
#2
TEST 1: AUNE DAC connected directly to the amplifier's PRE IN
Note:
Only the horns are connected, not the subwoofer.


The first track was Marie Bergman's "Someone To Watch Over Me" in Wave format.
This recording has the ability to mercilessly expose problems, especially where the vocals are concerned.

Immediately, the vocals appear a bit metallic, but never shrill - exactly as they should be with a very good amplifier.
Highly detailed; more than I've heard before.
The next thing that surprises is the drums' brush, which is absolutely sickly clear and natural.
The piano also appears very clear and natural, with far more detail than before.
The last thing is the double bass, which is also clearly present throughout, and the interlude is absolutely convincingly good.

The next track was Claire Martin's "Black Coffee", also in Wave format.
This recording has a very rare intro with high frequency drums, which were now more present than before, but something new also happened: It was there ALL the time throughout the song..?
The organ is given an unknown dimension of clarity; the same happens with all instruments.
The bass is tighter than ever, and very detailed and resolved.

Third recording was Basily's "Gipsy Treasure" in Wave format.
Acoustic guitars appeared here more lifelike than ever, as did the violin.
At least as important - the perspective is bigger and more open than before.

The fourth recording was Safri Duo's "Crazy Benny" in Flac format, which has an extreme dynamic and complex composition with many drum instruments.
This one was reproduced with more detail I've never heard before and the dynamics were insane.

The last recording was Deadmau5's "Right This Second" in Flac format.
This has absolutely insane sub-bass content, and is capable of killing any amplifier (and speakers).
Immediately - this amplifier has steel control on the sub-bass; I can boost the volume all the way, without any problems, and the detail remains - better than ever, and more detail is heard than before.



TEST PASSED
Very convincing - this amplifier is really good.

WOW!

I discovered something sensational:
There is absolutely NO background noise from the amplifier - it is COMPLETELY quiet, even if I turn the volume to max.

This has never been like this on any equipment I've owned.

One more thing:
The amplifier does not get hot at all; not even at prolonged high volume.
This is Solid State at its best.
