Lehmannaudio Stamp amplifier

This stereo power amplifier convinces with its intrinsic qualities: music lovers are wildly enthusiastic about the excellent sound quality of our Stamp. And with its compact dimensions, it amazes the audiophile world. Instead of yet another colossal power amplifier, we present this more than serious amplifier that holds its own anywhere, despite – or precisely because of – its size.

Even if you own small, trendy loudspeakers or listen to music through your second sound system, you can expect a rich and uniquely pure sound. The Stamp offers you exactly that, without stealing the limelight visually or sonically.

A sophisticated power amplifier

Like all our units, the Stamp will leave the Lehmannaudio factory with first-class components that produce a uniquely faithful and fascinating sound. Among others, we use components from Nippon Chemicon, BC Components and Epcos. To guarantee low-loss power delivery, we apply a 105 µm copper layer to both sides of the double-sided circuit board.

The internal audio wiring is completely solid-core. It is soldered directly to the terminals and the circuit board to avoid additional plug-in connections. The extra-large linear power supply is fed by a magnetically and statically shielded toroidal transformer. With dimensions of just 280 x 115 x 42 mm, the Stamp delivers up to 2 x 20 W into 4 ohms. Loudspeakers with a sensitivity greater than 87 dB/1 W prove to be perfect matches.

Installing this refreshingly different power amplifier is a piece of cake: thanks to its modest size, you can place it right next to your signal chain. With the optional mounting kit, you can also easily fix it wherever suits you best – for example under your desk or on the wall. Incidentally, if your loudspeakers have bi-amping terminals, you can reconfigure the Stamp in no time. For bi-amping you need two Stamp power amplifiers. In combination with our Linear, you get a pure preamplifier/power amplifier combination that will surprise you.

The owner closed the shop to help

I bought a second-hand soundbar from Audiofrenzy. The service is quick and friendly. I needed help getting the device into my car and the owner helped me straight away — he closed the shop to do so. Old-fashioned service and respect for the customer.
