Schiit - Replacement Tubes for Valhalla & Valhalla 2

The story of Schiit Audio begins with two veteran audiophiles Jason Stoddard, formerly of Sumo, and Mike Moffat, formerly of Theta coming together to shake things up a bit. Both of them have extensive experience in developing lots of audio and A/V products including the Andromeda III, Cobalt 307, DS Pre and Angstrom 200. From power amplifiers, I/V conversion stages, D/A converters, relay-switched stepped attenuator volume controls in preamps to developing the first DTS home theatre surround processor on the market, Schiit Audio has developed a lot of audio products over the years.

Headphones are the need of the hour everyone who likes music uses a headphone. Therefore Schiit Audio moved to develop personal audio equipment while continuing to design a speaker-based system which includes the industry-leading preamps, amps and DACs. So right now Schiit Audio has a plethora of audio products ranging from personal audio to speaker-based systems. Schiit designs affordable audio products that bring happiness in your lives.

Unlike ordinary DACs that use delta-sigma, NOS (new old stock) D/A chips, multibit chips, high-cost R2R ladders, Schiit uses unique DSP-based closed-form digital filter which improves the sonic performance of the multibit DAC. Therefore the Schiit's multibit technology brings all of it together using the current-production, medical/military grade D/A converters.

Schiit has opted for an innovative approach for the analog side as well. Even the most affordable Schiit headphone amplifier is a miniature, fully discrete, DC coupled, current-feedback power amplifier. Schiit is credited for introducing Continuity output stage to solve the issue of transconductance droop which was common in Class AB amplifier design. Schiit has also developed balanced topologies like Nexus in Ragnarok 2 and a perfect combination of tube and solid-state with Coherence in Lyr 3.

All the Schiit products are designed for solidity and durability. Even the smallest of the products are made of aluminium and steel while the larger products are made of high-end C core transformers, power supply filtering and low-noise control. All the products have to go through severe testing procedures including the latest APx555 audio analyzer and Avermetrics analyzers. Every product from Asgard and up goes through burn-in to address the issues faced during the initial period of usage. Schiit takes care of all the service and support requirements so that you can concentrate on great sound.

Schiit believes that local control of all the aspects of production improves the delivering of the product. Therefore all the Schiit products are designed and made in the USA and most of the cost of the components are going to the US-based companies. Assembled in the USA means that Schiit's chassis guys are from San Fernando Valley, Schiit transformers are made in California, Schiit boards come from the east coast of the USA and all the designing, assembling and testing of Schiit products happen in Valencia, California.
