MM8003

Multichannel Main Amplifier

MM8003 Multichannel Main Amplifier

At the heart of this amplifier is a massive high-current, audiophile-grade, oversized Toroidal power transformer. So it easily delivers more than 140W to each of the eight channels. In addition to its sheer power it incorporates high-grade audio components throughout, extensive shielding of key components, and ultra-wide bandwidth current feedback technology. The amplification system was originally developed to handle SACD signals, so it’s ideal for the new DTS-HD Master Audio and Dolby True HD formats. The chassis is completely copper-plated to deliver perfect grounding and to eliminate EMI. The result is an amazingly accurate tonal and image balance, allied to speed and dynamics with very low distortion.

Technical Details
