Tube character. Serious power.
The Stellar M1200 pairs a vacuum-tube input stage with a high-output Class D power stage. Two monoblocks provide an independent amplifier for each speaker, with the flexibility to connect a balanced or single-ended preamplifier.
Two M1200 monoblocks. The listed pair price includes both channels.
Stellar M1200 Monoblock Amplifiers (Pair)
Two technologies, one amplification path
A Class A input circuit built around a 12AU7 tube feeds an ICEpower Edge output module. The tube stage handles the incoming music signal while the switching output stage supplies the loudspeaker’s power. The result is a compact monoblock architecture with substantial rated output and lower idle consumption than a similarly powerful conventional Class A design.

A pair designed around your system
Use one chassis for the left channel and one for the right. Each accepts XLR or RCA from a preamplifier, and trigger connections can coordinate power with compatible equipment. Confirm the correct mains-voltage version for your installation, provide ventilation, and power down before changing speaker connections.
Make it work in your system
Thoughtful setup makes the difference.
Begin with volume control
Connect a preamplifier or a correctly configured variable-output source. Start at a low level and use the input type suited to your system.
Give the amplifier room
Leave ventilation and cable clearance. Check speaker impedance and mains requirements in the manual before installation.
Match power to the room
Speaker sensitivity, listening distance, and playback level affect useful headroom. Ask House of Stereo to help compare an amplifier with your speakers.

Before you choose
Common questions
Do I need a preamplifier?
Yes, you need a suitable source-selection and volume-control stage. This is a power amplifier, not an integrated amplifier.
Are speakers included?
No. This listing covers the amplifier package described above. Speakers and source components are separate.
Keep researching.
