Theta Digital Generation VIII Series 3 Preamplifier D-A Convertor
Theta Digital Generation VIII Series 3 Preamplifier D-A Convertor
The Generation VIII Series 3 delivers the most accurate, defined, natural sound that digital technology offers. It represents over twenty years of Theta Digital's tireless research and development in D / A converter design, and achieves the highest levels of sonic performance possible in a product category that Theta pioneered: the external DAC.

The G8S3 is a full differential, true balanced DAC preamp featuring custom-designed software-programmable digital filters feeding into two digital-to-analog converters per channel, one for each phase angle.

Theta Digital Citadel 1.5 Mono Amplifier
Theta Digital Citadel 1.5 Mono Amplifier
The Citadel 1.5 is a monoblock power amplifier offering all the advantages of the knowledge, research and dedication that Theta Digital has brought to its other amplifiers, and then some. The heart of the Citadel 1.5 contains fully-balanced differential, zero-feedback circuitry, and zealously selected solid-state devices throughout. We scrutinize the selection to optimize component parts in each and every stage, and for the performance of the amplifier as a whole. Custom-made capacitors, Vishay precision resistors, copper buss bars, Litz / Teflon wires and a custom-made output connector are just some of the components that combine to make the Citadel 1.5 an unprecedented technical statement. Sonically, this quality is expressed as a new level of veracity and intimacy in the experience of music, and in the prospect of movie soundtrack performance that no commercial theater can hope to rival. The Citadel 1.5's power supply design is an exercise in delivering massive brute power with absolute integrity. We give its output stage a high-current Kilowatt power transformer itself, which feeds a unique dual-choke and capacitive filtering system. This technique is rarely applied because of the huge choke size necessary to avoid impeding high current demands. Its filtering system employs two massive chokes almost as large as the power transformer. These are fed from an ultra-fast / soft-recovery 35 Amp full bridge rectifier, which are then filtered by two capacitive banks totaling 80,000uF. The synergistic effect of this filtering system results in high-current power supply lines that are more than 8,000% cleaner than conventional supplies. The sonic result of these super-clean supply lines to the output transistors has not previously been achieved at such a high power levels. The mechanical housing for the Citadel 1.5 is no less specialized than its internal components. More than an aesthetic statement, its seamless housing, devoid of traditional fasteners on top, front, and sides, provides a strong, stable environment for the operation of the amplifier. The power supply resides in its base, isolated from the amplifier module above. The

Theta Digital Prometheus
Theta Digital Prometheus
A collaboration between Dave Reich, Theta Digital’s chief engineer and Bruno Putzeys, class D "Wonderkind" of Hypex fame, Prometheus marks a fundamental departure in our amplifier philosophy. Rather than design amplifiers that highlight the amp/speaker interface and demand careful consideration when choosing the corresponding transducer, Prometheus is completely load agnostic.The frequency response is load invariant. Harmonic distortion, at less than 0.01% at 500 watts RMS full-band at 4 ohms is virtually non-existent. The same is true for IMD.

Theta Digital Casablanca IV Chassis
Theta Digital Casablanca IV Chassis
The Casablanca IV remains the finest sounding, most flexible preamplifier / processor available today even 18 years after its initial appearance in 1996. Continuous upgrades have maintained our vision of a reference-worthy multi-channel audio processor with audiophile performance, come-hither cosmetics and world-class usability and maintained essential contemporary features. The 2012 revision to the III HD brought a new, Dave Reich designed power supply with HDMI and lossless audio decoding. Today's upgrade to the Casablanca IV brings 4k HDMI video pass-through (when upgrading a Casablanca I, II or III. The 4k HDMI card is an option when upgrading the Casablanca III HD), state-of-the-art audio bandwidth to 192 kHz, increases DSP processing power by a factor of 10, adds world-class digital room correction and optimization from Dirac Live operating at a world-leading 96 kHz and our novel Jitter Jail II to fix insidious timing errors especially inherent in HDMI audio signals. Only Theta Digital has offered such quality and long-term value in this ever-changing product category.
