Alpha Design Labs (ADL) has now introduced an all-new product – the STRATOS. The STRATOS will be positioned above the ADL GT-40 (which will also have some enhancements). Though it hasn’t officially been announced as a replacement model for the ADL ESPRIT (my own reference DAC / headphone amplifier), I expect that this is likely the case, given features and pricing.
Building on the features of the GT-40 the ADL STRATOS brings something new to the table – DSD capability, a first for ADL. The STRATOS is truly a jack of all trades and quite possibly a master of many, having a built-in preamplifier, phono stage, headphone amplifier, DAC & ADC (24-bit/192-kHz), as well as DSD functionality (both 2.8M and 5.6M) via USB connection. S/PDIF optical input and output are also provided.
The STRATOS can thus serve as the hub of a music system and/or a work-horse of a desktop system. With it you can create pristine digital versions of your LP vinyl albums or get the most out of your headphones with robust amplification and the audiophile quality DAC.
Additional features include L/R analog inputs, switchable line or phono inputs and a controller that supports both ASIO and Asynchronous modes. The STRATOS also uses the finest Furutech RCA sockets to deliver high-quality sonic results. A clear step-up from the GT40 in performance, the STRATOS, has been reconsidered and rethought using the latest technology and the latest designs.
