The Special Edition of the Gram Amp 2 phono stage preamp features 50 percent more gain to deliver a higher output favoured by owners of passive preamps when using medium to high output (4.5mV or above) moving magnet phono cartridges. However, it can be used with all moving magnet, moving iron and high output moving coil cartridges.
Supplied with a basic ("green energy") power supply with self adjusting voltage, and with power-pins fitted to suit your power outlet — you can upgrade by swapping over to PSU1 power as and when you're ready.
