So Good We Went One Better

The “stonking” musical performance mentioned by Geoff Husband at TNT Audio magazine in 2001 just about said it all about the Gram Amp 2.

The legendary value-for-money of the Gram Amp 2 was etched into audio history right there and then.

However, to show this wasn’t a fluke we went one step better and made our best-selling budget phono preamp: the Gram Amp 2 Special Edition.

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.
