MA252 2-Channel Hybrid Integrated Amplifier
- Includes our Hybrid Drive™ technology that uses the best of vacuum tubes and solid state to produce the best sound performance
- Vacuum tube preamplifier and solid state power amplifier
- 100 Watts into 8 Ohms
- 160 Watts into 4 Ohms
The MA252 Integrated Amplifier is the first hybrid integrated amplifier from McIntosh. Taking retro design cues from the legendary McIntosh MC275 Vacuum Tube Amplifier, the MA252 combines the best of vacuum tube and solid state circuit design to create an amplifier that’s both visually and sonically stunning.
"The McIntosh MA252 offers an alluring combination of tube romanticism and solid-state resolution and authority... The ability to connect the listener to the music makes this tube-solid state integrated a special component by any standard. I could happily listen to the MA252 for a long, long time."
