STAX introduces a new semiconductor driver unit SRM-400S, the successor model of SRM-353X.
STAX custom-made low noise DUAL FET is installed on First Stage. And FET is also installed on Last Stage. The characteristics of right FET and left FET are measured strictly. Selected FET are installed as well as SRM-700S. SRM-400S succeeds to the design and the manufacturing method of the high end model SRM-700S, the amplifier which FET are installed in all stages.
In addition to the conventional power transformer for the high voltage circuit, the newly designed power transformer with the winding for the low voltage circuit is installed in SRM-400S. The low voltage winding enables to improve the power efficiency and achieve further power saving and better sound quality than the conventional driver units such as SRM-353X.
The new chassis which is more rigid than the conventional model is installed. The chassis has a hybrid structure using a lot of non-magnetic aluminum and further reduces the effect of the environmental noise factors such as vibrations. The inputs are RCA and XLR, the mutual exclusion inputs. The custom made concentric dual volume knob which is common to STAX products and RCA PARALLEL OUT functions are installed same as the conventional driver units. All electric components are strictly selected considering the environment. Also the sound quality and the performance is improved. The complete DC amplifier configuration that the signal circuit includes no coupling condensers is one of the biggest traditional features.
SRM-400S takes over the high resolution sound which is unique to the semiconductor circuit and dynamic low range sound reproduction. Simultaneously, the good sound balance is further pursued than SRM-353X. From the low range to the high range, the sound of each range is well harmonized. Not only for the combination with the advanced lambda series, SRM-400S is also ideal for the upgrading from the entry level SRS-3100. This is the promising new model which covers from beginners to intermediates among the renewed driver unit lineup.

Talk about hifipro
It was in 2016 that the idea of an e-commerce site for the sale of new products was born: HIFIPRO. Mario Gagnon, owner of the second-hand Audio store since 1985, nurtured his passion for music since childhood. This enthusiasm allowed him to excel in his studies and projects. Dedication, time and love for sound and its reproduction led him to open his own store. It will quickly become a reference in the sale of high fidelity devices in Canada. He and his colleagues spend a lot of time following progress and new developments in order to stay up to date with the latest technologies. After more than 30 years of success, Used Audio has acquired a very loyal customer base, participated in and obtained several recognitions from consumers and professionals during several exhibitions. For several years now, they have been shipping items across Canada, so Mario decided to create HIFIPRO. It is with great confidence that he and his team are ready to offer you the best products and services. Our goal is to help you make the best possible choice according to your needs and criteria.
