The entire design including the chassis has been optimized for the mono configuration, further lowering the cross channel interference.\u003c\/p\u003e\n\u003cp\u003eOther Circuit Enhancements\u003c\/p\u003e\n\u003cp\u003eThe original 10A bridge rectifier has been replaced by a 50A Schottky diode, the capacitors upgraded 30,000 micro-Farad, and duly the power transformer is now rated at 300W. Improved circuit layout with careful component selection has allowed the ST-10M to have a lower noise floor than the ST-10.\u003c\/p\u003e\n\u003cp\u003eThe NuPrime Sound\u003c\/p\u003e\n\u003cp\u003eThe ST-10M sounds more full bodied and rich, conveys greater immediacy and power as compared to the ST-10. The improved power delivery and reduced interference gives the instruments richer overtones and more natural decay. The soundstage is deeper and creates a greater sense of space. Imaging gains more solidity over the ST-10 which already has an impressive placement.\u003c\/p\u003e\n\u003cp\u003eThe effects of the improvements could be heard on the following examples. The striking of piano keys demonstrates greater attack and faster transients, with a sound that naturally resonates with the piano body.\u003c\/p\u003e\n\u003cp\u003eBrass instruments sounds glorious, characterful and carries a natural sheen but not overly bright. Female vocals and high frequencies retains the signature of the ST-10 but is smoother on the ST-10M. In an ensemble, the tonality gains an extra notch of richness which makes the overall presentation more natural.\u003c\/p\u003e\n\u003cp\u003eWith the ST-10M, every aspect of the ST-10 sound has been improved upon, which makes it truly a reference grade amplifier!\u003c\/p\u003e\n\u003cp\u003eNote: The \u003cstrong\u003eETI BP-20C \u003c\/strong\u003ebinding posts used in current production have higher quality than the ETI Cable Pod binding posts used in older production batches.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInputs:\u003cul\u003e\n\u003cli\u003eRCA: Un-Balanced input x 1\u003c\/li\u003e\n\u003cli\u003eXLR: Balanced input x 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOutputs:\u003cul\u003e\u003cli\u003eSpeaker Out x 1\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003ePower Output (rated): 230W @ 8 Ohms, 320W @ 4 Ohms\u003c\/li\u003e\n\u003cli\u003ePower Output (peak): 270W @ 8 Ohms, 375W @ 4 Ohms\u003c\/li\u003e\n\u003cli\u003eGain: x 28\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 47k Ohms\u003c\/li\u003e\n\u003cli\u003eSensitivity: 1.5Vrms to rated power\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion (THD): 0.01%\u003c\/li\u003e\n\u003cli\u003eSignal to Noise Ratio (SNR): 91dB @ 10W\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 0Hz to 50kHz (-3dB)\u003c\/li\u003e\n\u003cli\u003eRated \/ Peak Current: 10A \/ 18A\u003c\/li\u003e\n\u003cli\u003eStandby Power Consumption: 0.9W at 115V outlet, 1.7W at 230V outlet\u003c\/li\u003e\n\u003cli\u003eIdle Power Consumption: 14W at 115V outlet, 14.8W at 230V outlet\u003c\/li\u003e\n\u003cli\u003eWorldwide AC voltage: (115 VAC \/ 230 VAC) with Voltage Select Switch\u003c\/li\u003e\n\u003cli\u003eAC Fuse: Slow-blow, 5A, 250VAC\u003c\/li\u003e\n\u003cli\u003eDimension: 59 mm H x 215.4 mm W x 394 mm D\u003c\/li\u003e\n\u003cli\u003eWeight: 6 kg\u003c\/li\u003e\n\u003cli\u003eColor: Black \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eST-10M is a phase inverting amp.
