“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 pre-amp: 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.

Launched Stateside

Shortly after the launch of the “beer money” Gram Amps in 2000 we were asked if we could make an even-better version for the US market, and the Gram Amp 2 Special Edition came into being.

It quickly picked-up awards and recommendations from a number of US Hi-Fi publications because of its “bang for the buck”.

Since then its design – both in audio performance and appearance – has been refined a number of times.

Each time it has been judged by customers and magazine reviewers – and has not been found wanting.

For such a low-cost, small and lightweight phono preamp, it has proved itself capable of delivering a blistering musical rendition.

As might be expected the Special Edition has become a much sought-after dedicated MM phono preamp amongst record fans in the UK and Europe as well as in the US.

Cartridge Partners

The Special Edition will not be found lacking in the company of the best high output cartridges.

But where budget dictates, less-costly cartridges like Audio-Technica’s AT95E will still let it produce a highly satisfying sound.

The Gram Amp 2 Special Edition phono preamp won’t stamp any “signature” on your music so you’ll be able to hear all the qualities of your cartridge.

It will be a lasting part of your hi-fi system, and won’t be easily outdone by upgrades to the rest of your system.” – GSP Audio
