Product Details

Struss Audio is a high end manufacturer with over 40 years experience and the Struss Audio Ultimate amplifier is the pinnacle of all that experience resulting in a product that really is the ultimate. The name says it all!

Designers of Struss Audio have once again reached a new level on their way to perfect sound. The Ultimate amplifier is more subtle and noble, clear and spatial, powerful and confident. Anyone looking for the full sound of outstanding power, consistency and musicality – will find them in this device. The Ultimate is an integrated amplifier with the possibility to use the preamplifier and power amplifier separately. It has been designed in a dual-mono system (balanced), which is an extension compared the previous model. It features two very efficient transformers. They are magnetically and electrostatically isolated, each with a power of 600W. The amplifier receives enough power to drive any speaker. The power of 250W at 8 Ohms makes the Ultimate a beast. Both channels work in a balanced configuration. There is no coupling capacity in the whole acoustic channel. It’s a clean DC circuit. The amplifier has been built in the J-FET / FET technology. Dynamics and speed are features you will immediately notice.

The preamplifier is a new solution. It was decided to opt for a passive circuit that supports all linear inputs. It transmits the signal from a CD player, DAC or streamer through the volume control directly to the power amplifiers. The passive preamplifier design has been maximally minimized. The Ultimate uses an advanced constant input impedance, high-sensitivity circuit that matches the line input specification. A turntable can also be connected. With both MM and MC cartridges. This part of the preamplifier circuit, similarly to the linear one, consists only of discrete elements. The phono section will surely provide an unforgettable experience for fans of analogue records. The Ultimate also means:

  • Massive housing optimised for the presence of resonances
  • Shortest possible signal paths
  • Magnetically and capacitively neutral electrical system
  • Full security and protection for your speaker outputs
  • Enhanced HPCS system (Struss Audio’s patent)
  • High quality RCA, XLR and speaker jacks
  • Metal remote control
  • Processor isolated from the signal path for remote control

The Ultimate is an innovation that is in line with the classics. The task of the amplifier is only to deliver a perfect musical message. The construction has only the necessary features, because the most important are the acoustic qualities. It’s a very accurate sound with a real rendition of the space and atmosphere of the recording. It is distinguished by great dynamics, tonal balance and an exceptional, intimate aura which it generates from the first bars. This makes the Ultimate an amplifier with the highest sonic parameters. For those who love the charm of the lamps, but are looking for a strong amplifier transistor, the Ultimate is an excellent choice.
