I'm selling my XI Audio Formula S including the Powerman, its linear power supply.

Both the devices are in perfect conditions and have always worked flawlessly. I've owned several amplifiers in my "audiophile career" and this is certainly one of the very best ones I've ever had and enjoyed. At the moment I own way too much gear which doesn't get used enough so am trying to downsize a bit. More classifieds will follow in the coming days...

The Formula S offers plenty of power, even for the most demanding headphones. It's built like a tank, in a very simple yet appealing design. Its compact form factor makes it ideal both for a hifi rack or a desk.

The amplifier and the power supply come both in their original packaging.

Price does not include 3% PayPal fees and shipping. Happy to ship anywhere in the world but buyer pays PayPal fees and carrier of his/her choice.

For convenience, this is the conversion of the price in the most common currencies, at the current respective conversion rates (note that the payment will have to be made in CHF):
- 3435 EUR
- 4050 USD
- 2918 GBP

The following is a set of quick pictures I just took of the two devices. Appreciate it's not the best quality but happy to share more upon request so please feel free to send a private message in case.
