accustic arts amp1


POWER I highlights

Integrated stereo power amplifier with high output performance

8 selected MOS-FET output transistors of highest quality

Exclusive usage of Burr Brown® ICs

Magnetically shielded and encapsulated 550 VA toroidal core transformer
of premium quality for high output reserves; separate windings for preamp section, for power amp section and for left and right channel

Very good smoothing thanks to more than 80.000 µF power supply capacity

Very high damping factor

Integrated protective circuit switches ascents off when clipping, HF oscillations or too high DC offset occurs

Constant low operating temperature due to generously dimensioned heat sink integrated in housing

3 x unbalanced inputs (RCA)/1 x balanced input (XLR)

2 x preamplifier-outputs (1 x balanced/1 x unbalanced)

Premium quality relays and premium quality rotary switch with gold-plated silver contacts for the input selection

Encapsulated high grade volume potentiometer

Fully aluminium-made remote control

Full metal housing for optimum shielding

ACCUSTIC ARTS® POWER I is „Handmade in Germany“

Einstein The Absolute TuneThe sonic signature is determined by the valve input stage and entirely independent of playback levels. ‘The Absolute Tune’s persuasivenes rests squarely on explosive speeds, finely nuanced microdynamics and unmitigated transparency.

2004: The image hifi Award 2004 in the category Integrated Amplifiere goes to Einstein for The Absolute Tune

PRE 1 MK 3 (BALANCED) Since the review the preamp has been updated to MK 3, the changes have updated the already excellent sound to a yet higher level. In our opinion this is now a faultless product and more than capable of standing any competitor in this price sector making it the one to listen to. In short you have innovative circuit designs using world class components and excellent German engineering, leading to a world class product within its sector. A best buy!

Boulder 810 Preamplifier Like its predecessors, the 810 Stereo Preamplifier features balanced, dual-mono, three-stage instrumentation-style circuitry. This eliminates any trace of noise, distortion, or impedance issues that may affect the delicate audio signal. Musical dynamics and detail emerge effortlessly from a black and silent background. Images are superbly defined and separated with a wealth of revealed low-level information.

Accustic Arts AMP IIt should be obvious by now that when it comes to treble performance; I regard
the Power 1 as the bee's knees particularly for a solid-state amplifier. In this regard, it is perhaps the best I've ever used. It illuminated treble details as no other amplifier I've heard,...
...Through the midrange, the Power 1 was as transparent as just about any amplifier I recollect ever hearing...
