Graham Slee Reflex C - MC Phono Stage Preamplifier

• The Reflex C is supplied with the PSU1 power supply, and a choice of voltages and power plugs; 100 Ω or 1k Ω input impedances; and there is also an option to have a mono switch fitted.Moving coil cartridges output somewhere in the region of 0.1 - 1 mV - they're low output.
• The idea behind the moving coil cartridge is great! By making the magnets fixed to the body, the stylus moves the coils of wire instead. The coils of wire are made really light by using only a small number of turns, which means there's much less inductance compared to moving magnet cartridges.
• This results in a nimble cartridge whose frequency response goes much higher, and without the inductive peaking you get with moving magnet.
• But everything has its downside, and with moving coil it's the phono preamp electronics that haven't kept pace with the progress the moving coil cartridge made.
• Overcoming The Physical Difficulties of Phono Preamps
• The output of a moving coil cartridge is so low that ultra-low noise electronics are needed to amplify it.
• Ultra-low noise means the input stage has to be restricted in its "latitude" and so the input easily saturates on loud passages and record noise (clicks and pops).
• Loud and "busy" musical passages become harshly distorted - even if the specifications declare the opposite - audio analysers can only measure steady state.
• Inputs which easily saturate also have poor slew-rate - the "processing speed" is slow and leading edges of the music signal are curtailed - it's called slew-induced distortion.
• The Reflex C Gives You The Freedom To Choose
• The Reflex C uses low-noise video amplifiers which overcome the difficulties of input saturation and slew induced distortion.
• You can play the music you want! Throw the fastest tempo music at the Reflex C and you'll marvel at its pace.
• It captures all the subtleties of your music - all its detail - plus it projects a really convincing and articulate stereo image - and much less in the way of clicks and pops.
• The Reflex C is the answer to moving coil preamplification you've been waiting for.
• Suitable Cartridges
• The Reflex C is suited to low output moving coil (MC) with output in the region of 0.2 - 1.0 mV (ref 1kHz at 5cm/sec)
• Cartridges having lower outputs may be used if you accept the risk of hearing more hiss than you may be comfortable with.
• Your amplifier's volume control is intended to be set to give you the loudness you want and should be adjusted accordingly. With the lowest output cartridges you will need to turn the volume control higher than you would use with other sources such as a CD player.
