I now have the speakers of Louis Raatjes. He is a musician And has ears to make the most beautiful speakers! The drivers are original Audax, but with exceptionally good components. For this we use silver cables. Everything along with the EWA-M50 happens something magical. I hope you can come and listen to what you've made! This is the first time i feel the music! Thx Colin From Johan De Zutter
Our new, and we think revolutionary cables, will be available as Speaker cables, Interconnects and Mains cables. The cables follow on from Colin Wonfor's previous designs by adding improvements in the noise cancelling / rejection area. The main design objectives for all the cables were Remove as much common-mode noise as possible from the signal. Ensure that the cable itself itself does not generate any noise / RFI. Make the cable as immune as possible to external noise. These objectives were applied to both Signal level cables (Interconnects / Loudspeaker) and Power cables (Mains). Performance data for each cable will be published in due course.
Specifications for the M50 Stereo Power Amplifier. Input. The input impedance is 22KΩ Input sensitivity for full power is 1V providing 50W into 8Ω both channels driven. Output. Power rating 50W/8Ω both channels 100W/4Ω both channels DC offset < 5mV Noise open input < 2mV Peak Current > 64 Amps peak. Bandwidth 10Hz – 120KHz ±1dB Damping Factor > 100 Power Consumption. Mains on standby < 1W Power on no signal < 40W Power Supply. The aux standby power supply is used to soft start the main amplifiers power supply. The main PSU consists of a 350VA transformer and four large 10,000µF/50V bulk capacitors.
Mike Brailsford I own a prototype of this amp, and up until I heard it in my system I was pulling my hair out that my PMC 21's weren't doing it for me ( we wanted small standmounts ), yes they had speed, clarity and imaging but lacked a little in the bass, but as soon as I connected to the EWA M-50, holy moly my PMC's came alive! So much so that I'm not actively looking to rid of the PMC's now 😊 Highly recommended that you try and demo EWA's new products, I think you'd be impressed 😊
