Sound:
Shortly after starting the amplifier sounds very unpretentious, with under emphasized bass and clear treble
after a few minutes the typical tube sound is noticeable: very warm in slightly accented bass and soft, velvety in the vote, easily understandable and in the heights clear.
BT transfer some frequencies being transmitted to victims seem to have fallen and so this seemed a bit counter of Basslastigkeit what first of all even clearer sound 'at the expense of space. The sound is indeed 'crisp', but the definite place of sound elements such as at concerts or well-mastered studio recordings is not optimal.
for playback via cable tieftönige elements 'present in the recording' very warm, but not as crisp as of 'modern' amplifiers, are listed. But this is typical of a 'tube'. For voices and instruments in space are given well locatable and fine treble again very clear and precise.
Power:
I have the amplifier for testing purposes with 2x2.5mm ^ 2 oxygen-free copper cable of approx 2m connected to two ELAC BS184 'this 2-way bass reflex speakers with ribbon tweeters would like 75 watts into 6 ohms. Already at a controller position of about 1/3 the room volume was far exceeded 'further testing I did not have there. Experience has shown that the expected ELAC an amplifier with sufficient power reserves to sound at low frequencies well, such as a traditional Harman / Kardon. For the Auna mini tube amp that was a no-brainer. By comparison, the boxes usually run in a 5.1 setup on a Yamaha RX-V773. This was in spite of 7x150 watts a satisfactory setter and in the bass so pale that he has received a 5-channel power amplifier Rotel as support. At this the ELAC's sound although linear and precise bass response, but not even 200 years of Auna plays as well with.
Unlike many low-cost Class D amplifiers with external power supply of Auna will also stop at the performance clearly, what it promises. In the lower power range it is even so high current that he can keep up with the warm, clear sound old H / K-amplifier.
Positives:
+ Impeccable processing 'all past, nothing wobbles, nothing cracks
+ Switches raced a solid and have a good resistance, accidental activation is almost impossible
+ Neat, gilded boxes terminals' as could be many 'Japanese' a leaf
Easy to assemble boxes + terminals with 2.5mm ^ 2, banana plug-compatible
+ Protection circuit of the final stage of activation and deactivation
+ Integrated power supply
+ Enough power 2x25 watts are absolutely realistic
+ With good cables absolutely no noise, even at full volume
+ Smooth BT pairing (but without authentication, see Negative)
+ BT connection remains when switching to another source are made, you can nearly without interruption from CD or AUX switch back to BT
Neutral:
= Volume control something smooth
= Pretty sharp edges on the front and rear panel of the CNC machining
= The Bass Boast is given the warm sound image superfluous
= Fixed connection cable
Negatives:
- BT pairing occurs without authentication 'any device within range can connect
- BT connection is sufficient in some cases less than 5 meters wide, because the metal housing of the device, the antenna shields strongly forward. Also everyone is BT typically been a serious obstacle for the signal transmission.
- Slight regular cracking in the BT connection, only to hear if just nothing is transmitted and at high volume
- The packaging is very robust and protects the amplifier good, but the styrofoam stinks and smells so unfortunately the amp slightly.
- The included 3.5mm jack cable (male-male) is absolutely not shielded and an antenna rather than a connecting cable
Recommendation:
The amplifier is suitable for lovers of music that demands not to high demands on dynamics and precision in the bass. Jazz, rock and classical music are not a problem, messages and spoken long texts also sound great. Pop and electro are more likely not the domain of this equipment, 'but still sound good.
Sound, processing and power reserves are at a high level and are also demanding loudspeakers justice.
When playback via Bluetooth expectations range and immunity should respect. Not be too high 'Who does not want to lead, but happy anyway, as long as it moves in the lobby. It will be exciting when multiple devices are in range 'due to lack of authentication when pairing to get probably rapidly into the enclosure.
