  2. Canary Audio M330

    Retail $12900 with EH GOLD 300B
    Built around 300B Triode Tubes: The M330 is a class A triode mode, push-pull monoblock power amplifiers with the use of two matched 300B triode tubes per channel. It features an advance circuitry that guarantees a deeper bass tones and crisper treble. The M330 is capable to deliver 26 watts of power per channel. This is achieved by the use of a massive, custom-built power and output transformer specially designed by our engineers.

    Like all other Canary products, the M330 is 100% handcrafted in California with the use of finest parts and components. When you listen to the M330, you just might not think of them as amplifiers at all. Those who have listened closely say that it sounds like music, not like an amp. Only the glow of those matched 300B will let you know otherwise. It's that simple. Rated Power Output: 26 Watts RMS Input Sensitivity: 0.72 Volts for full output Input Impedance: 150,000 Ohms Frequency Response: +/- 1dB from 10 Hz to 70,000 Hz Total Harmonic Distortion: < 0.4% Signal-to-Noise Ratio: -83 dB below 1 Watt Damping Factor: 12 Power Consumption: 240 Watts (true RMS) Output Impedance: 4, 8 Ohm Tube Complement (per monoblock): 2 x 300B
    2 x 6SN7
    Dimensions (per monoblock): 10" W x 17.5" D x 8" H Net Weight (per monoblock): 35 lbs.
