DLS A6 amplifier - najboljši na testu

DLS A6
The next things that impress are its tactile qualities and the choice of materials. Cooling elements and side parts are made from special anodised and brushed aluminium. The connectors, controllers and switches are covered with gold. In order to connect a cap, the analogue A6 has a separate terminal. For speakers there are two pairs of terminals, allowing two woofers to be connected without any trouble at all. The jumpers are internal.

Specifications
From the configuration point of view, the A6 Version 2 is purely intended for the bass end range. Frequencies above 125 Hertz with 12 decibels per octave are blended out. The fair Swede provides us with a new feature on the remote control. In additional to a level regulator, there is a phase regulator which can be adjusted with a screwdriver. It is especially good that this can also be done from the driver's seat.  Frequencies less than 25 Hertz are filtered out by a subsonic filter with a rate of change of 18 decibels. As a safety guard there are four 35 amp safeguards. In the laboratory, the DLS pumps it out the best. Not only does the gigantic dampening factor of 1913 on average contribute to this, but also the very low distortion rate of 0.008 per cent with five Watts. In terms of output, it put out 515 Watt with four Ohm, 789 Watt with two and 1241 Watts with one Ohm. More than enough to power even two woofers with enough juice.

Listening test
The A6 is suitable for both sound and performance with its dynamic, powerful and rounded output. The DLS is not fazed by any sort of burden and controls four and two Ohm basses equally well.

Summary
What possible differences could there be between mono amplifiers? After all, they all produce bass, don't they? While this may be true, there are also some serious differences as we have just seen in the low end and power differences. Most of all it is amplifiers working in class D operations in this test field that are really kicking, as if they were playing right down there in the cellar. Amps that work at class A and A/B levels are mere cellar children. They obviously have no worries about passing the bass threshold and perfectly feed even the deepest of tones to the woofer. DLS has both of these at the ready with the A6. It only looses marks when it comes to dynamics. We can but speculate whether the high dampening factor is responsible for this.

Scoring
The DLS wins in two categories. It not only offers flawless readings, it will also dazzle you with its sound quality. In the lab it was the high dampening factor of 1913 that really stood out. This ensures that even with a two Ohm strain the woofer stays under control at all times. The LRX came up directly behind the A6 in the lab category. If it had had more output and an even higher dampening factor, the two would have won joint first place. When it comes to output, the Emphaser is not a patch on the winner. It is a shame that it just lacks power in the deep bass range. But this is actually the case with all class D amplifiers from the test field. As soon as the sound really goes deep down into the foundations, the volume subjectively diminishes a little, even with different woofers. If it is power you are looking for, however, there are no alternatives. SPL Dynamics came out worst in this test.
