Struss Audio Ultimate Integrated Amplifier | Hifi Pig Struss Audio Ultimate : un ampli Hifi bien tradi par une quadragénaire polonaise du High End (on-mag.fr) Purchased in October 2021 - MINT Struss Ultimate – an audio amplifier allowing for separate use of preamplifier and power amplifier. Built in J-FET / FET technology, dynamics: 135 dB.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 resonancesShortest possible signal pathsMagnetically and capacitively neutral electrical systemFull security and protection for your speaker outputsEnhanced HPCS system (Struss Audio’s patent)High quality RCA, XLR and speaker jacksMetal remote controlProcessor isolated from the signal path for remote controlThe 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.SPECIFICATIONSPower: 2 x 250 W/8 ? (CLASS AB) - 2 x 400 W/4 ?
