The character of the unit is solely created by the SQ Phillips NOS pentode tubes and the Lundahl interstage transformers. There are two C-core transformers available, a silicon iron core and a nanocrystalline core, and the Sora design allows the user to toggle between the two transformers during operation. While the silicon iron transformer represents a \"normal\" transformer with some character, the nanocrystalline transformer has virtually no hysteresis, thus adding no coloration throughout the audio range.\u003c\/p\u003e  \u003ch3 id=\"toc_1\"\u003eTRANSPARENT PROCESSING AND FLEXIBLE FREQUENCY CONTROL\u003c\/h3\u003e  \u003cp\u003eThe rest of the circuit utilizes the best available JFET-input IC operational amplifiers (OPA828) for absolute transparency.

The preamplifier pays homage to West-German engineering from the 1950’s while utilizing modern components and construction techniques. The front end is based around the Telefunken EF804S, a very special and sought-after NOS pentode, combined with a high step-up ratio Lundahl input transformer. The most distinctive feature in the classic German 1950s designs was the use of pentodes in the first stage of sensitive electronics. \u003c\/p\u003e  \u003ch3 id=\"toc_0\"\u003eHIGH GAIN LOW NOISE FRONT END\u003c\/h3\u003e  \u003cp\u003eThanks to the special front end, the self noise of V804 PRE is very low, fully comparable to the best solid state rivals and the maximum gain is also very high. The latter of the two tube stages in the amplifier also features a SQ pentode, the E180F. This stage is also coupled to the outside world through a Lundahl transformer. The core of this transformer is silicon iron which adds a hint of thickness and smoothness to the top register.  The gain of V804 PRE is adjusted in 4 dB increments via an Elma rotary switch. The gain adjustment is equipped with an automated -20 dB pad for the lowest gain settings.
