ACCUSTIC ARTS : AMP I MK2
Audiophile stereo power amplifier with high output performance

AMP I - MK2 highlights

• Audiophile stereo power amplifier with high output performance; also suitable for less efficient, impedance critical and low ohm loudspeaker systems down to 2 Ω
• 8 selected MOS-FET output transistors of finest quality
• Magnetically shielded and encapsulated 600 VA toroidal core transformer for high output reserves; separate windings for right and left channel
• Very good smoothing thanks to more than 80.000 μF power supply capacity; premium quality capacitors (“Made in Germany”)
• High damping factor for perfect speaker control
• 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
• Balanced input (XLR) and unbalanced input (RCA) – the inputs are switchable
• All used components and parts are selected and of highest quality
• Very high quality, gold-plated speaker terminals
• Full metal housing for optimum shielding
• Front panel made of brushed aluminium;
• inlay made of massive, chromed brass
• ACCUSTIC ARTS® AMP I - MK2 is „Handmade in Germany“
