cost a lot more. We’re looking for ward to reviews.
1) Accustic Arts AMP II MK2 Power Amp – $13150
The driver stage of the AMP II – MK 2 works on the principle of the current mirror. This circuit principle enables power to be drawn from an existing current. The AMP II – MK 2 is therefore a “power-controlled” output amplifier whereby the large number of MOSFET transistors ensure a very high current capacity without having to stretch the transistors to their performance limit. The AMP II – MK 2 is therefore also suitable for impedance critical or low-ohm loudspeaker systems. Ingenious circuitry removes the need for a servo controller for the “offset” and the quiescent current is generated via the IC or current mirror driver. As a result, direct and alternating current errors (DC and music signal errors) are immediately corrected. This means the total offset is exclusively determined by the quality and symmetry of the used ICs.

2) Accustic Arts Tube Preamp II – $10750
The general concept of the TUBE PREAMP II – MK2
The ACCUSTIC ARTS® TUBE PREAMP II – MK2 is a preamplifier with an exceptional and uncompromising design along the lines of the so-called tube-hybrid concept. This concept, also an integral part of our TUBE-DAC II, combines the advantages of transistor technology with the advantages of the tube principle. Tubes are excellent voltage amplifiers, but can only supply a limited amount of current. As a result, in the TUBE PREAMP II – MK2 we place the tubes exactly there where these clear advantages can influence the acoustic pattern, i.e. for the voltage amplification. In places where current has to be supplied, e.g. for impedance conversion, we use the proven premium IC OPA627® from Burr Brown / Texas Instruments. This combination allows us to achieve very low-resistance outputs which are also characterized by a high current capability. We use solid state technology and tubes to take advantage of their physical characteristics to realize an exceptional, analogue sound experience with an extremely low harmonic distortion and excellent harmonic distortion spectrum which sets standards.
As opposed to most tube preamplifiers, the TUBE PREAMP II – MK2 is in fact fully balanced, i.e. with 4 completely separate amplification stages from the signal input to the signal output.
The 4 amplification stages are divided into one inverting and one non-inverting signal path per channel. Each of these amplification stages contains a high precision tube manufactured according to military specifications. This principle enables perfect channel separation.
The loudness is adjusted via a high-end selective, high precision 4 channel potentiometer. It is natural that the TUBE PREAMP II – MK2 functions completely according to the proven Class A principle.
