• The TIDAL Prisma. Transparency and invisibility at a new level. The Prisma does exactly two things only, and it does it in absolute perfection: selecting the source and adjusting the volume. It has to be experienced to understand the game-changing way it does this. It takes itself acoustically completely out of the way between the source and the power amplifier. The unique concept, the TIDAL pre-amplifier topology itself, and the execution of the complex multilayer PCB board are the inner heart of the unique performance. On top of all that the Prisma comes with our legendary fully balanced MC phono input. A line stage like no other, as always embedded into our timeless and iconic TIDAL cabinet and built-in perfection.
  • The TIDAL Intra results from the uncompromising implementation of our most basic requirement: pure amplification of the musical signal without adding any sonic color or concealing even the smallest details.  With it, we offered TIDAL amplification in the same cabinet size such as the Prisma and Camira. What might look at a first view as a multi-channel purpose amplifier - is more than that. The TIDAL Intra is first and above all a high-end stereo power amplifier. It contains two physically divided stereo modules, built like a dual mono power amplifier. For true stereo power amplification, one channel per module per speaker side. Then each main power supply for each module takes care of only one channel - for ultimate 2-channel sound. The options on top of that are built inside already: one could also connect with two channels per speaker for passive or active bi-amping. Or one does integrate the TIDAL Intra into a high-end multi-channel system. Intra can also be bridged for subwoofer applications with the TIDAL LPX technology.  The Intra offers true stereo excellence!
  • We have pushed the concept of the Impulse stereo power amplifier to its extreme and developed an all-new 1.600 VA power supply with true power regulation. Thus, the TIDAL Ferios mono amplifier board is certain for all practical means and purposes to be supplied with never-failing power reserves and a lavish feed of clean current that will easily drive every imaginable speaker. The generous supply of additional power is merely a welcome byproduct. The real goal was the absolute relaxation with which the Ferios performs, to the extent where any attempted description of sound attributes becomes meaningless. The Ferios is quite simply a benchmark for amplification in this size.
  • The TIDAL statement power amplifier in monoblock fashion. The Assoluta is the finest we offer to amplify the most delicate music signals to ultimate power. The Monoblock offers all the loudspeaker's grip and control without adding color to the signal.  The result we have accomplished is beyond the trial to get an idea out of the provided specifications, data, and used technologies. Silence. Finesse. Endless control. Music in its true beauty.
  • Not The Typical Class A

    The Rei employs a WestminsterLab proprietary iBias and CCS systems, what it means in terms of electronically. The Rei will warm up much faster than other typical Class A amplifier, and the iBias technology constantly varies the bias depending on the current and also the loading of the amplifier. And the result sonically, is you get the best of the Class A without the typical draw backs. Is truly unique.

  • Completely redefines what the preamplifier's can do in your system.

    The ultimate aim of the Quest is to create the perfect preamplifier to accompany the Rei and the cables lineup. With the Quest, it completes the loom between your source and pair of speakers. Setting out to push the boundary, it redefines how a preamplifier can contribute to the system and the ability to extract every bit of potential from both the recorded music and the music reproduction system.

  • Of course, it is digital conversion that lies at the heart of the C1.2. The perfect preservation of time and amplitude information is critical to reproducing musical signals stored in digital formats and we believe that the advances incorporated in the C1.2 build significantly on the solutions adopted in the C1, taking digital performance(s) to a whole new level. Both noise and jitter are central to the design of any high-performance DAC. We have developed an entirely new MEMS-based, shunt regulated and thermally compensated clock for the C1.2, improving clock accuracy significantly (as well as providing highly developed clock-sync and external reference clock options). A four-fold increase in processing power has allowed us to further refine the proprietary CH-PEtER algorithms, introduce 32-bit fixed point processing and increase input compatibility to include all high-resolution digital formats, whether from optical or file replay sources. Our proprietary CH-Link HD interconnection allows the transfer of native DSD and MQA data in the digital domain, from the D1.5 transport to the C1.2. The AES/EBU and S/PDIF inputs accept PCM at up to 192kHz/24bit resolution, while the HD streaming input will accept PCM data at up to 768kHz/32 bit resolution and DSD512(8x). Local regulation of the DSP and FGPA further reduce the system noise floor. The DAC itself employs no fewer than four converter chips per channel, in a fully differential, dual-mono topology. The vital analog output stage is discrete, fully differential, Class-A and DC coupled. The modular input architecture ensures that the C1.2 remains future proof, able to adapt to changing digital standards or system demands.
  • The heart of any disc player is the transport mechanism itself. But what do you do if current mechs simply aren’t up to the job? If you are CH Precision, you build the CH Precision D1.5! The carefully selected optical pick-up and motor are precisely mounted on a massive brass sled that weighs almost 1kg (2.2lbs). This high-mass lowers the mechanical resonance frequency of the module several orders of magnitude lower than in most other transports, while ensuring an ideal counter-weight to the torque of the spinning disc. The critical mechanical parts of our proprietary Mechanically Optimized Reading System (MORSe) are built entirely in-house. The complete module is isolated from the rest of the chassis using four alpha-gel isolators, fine-tuned to filter vibrations all the way down to AC mains frequencies. This prevents vibrations generated by the spinning of the disc from reaching sensitive electronic boards, as well as low frequency vibrations originating in the power supply or chassis disturbing the accurate tracking of the laser mechanism.
  • The problem is, that as soon as you have more than one box (and one master clock) in the system – for instance, if you use a transport and DAC – then the errors can increase exponentially. The easiest solution is to synchronize the two clocks, designating one as the master and slaving the other to it. That’s exactly the solution provided by the Clock-Sync cards available for the CH Precision D1, C1 and I1, while the sophisticated software control incorporated into each of the units allows owners to designate master and slave according to circumstances and system topology. But what’s better than syncing two or more units to a single master clock? Syncing them all to a single, superior, external reference point – a reference like the T1 Time Reference external clock. The T1 generates a super accurate, low-jitter signal that delivers measurably lower phase noise and more accurate transfer and conversion of digital signals. It is built around a high-frequency 10MHz oven controlled oscillator (OCXO), its core temperature and output further stabilized by encapsulation in a mechanically isolated billet aluminum block. Why not just use one of the popular and readily available Rubidium clock modules like everybody else? Because those Rubidium modules have a limited life span – generally between six and eight years – and they contain radioactive material. At CH Precision we expect our products to have a much longer working life than that, so incorporating components with a finite life is contrary to all our beliefs – especially if those components then present a serious disposal issue.
  • This is one area of technology where size really matters – just not necessarily in the way that you might assume. The critical circuits in your audio system run on DC voltage. The level of that voltage needs to be precise and the level of residual noise it carries needs to be as low as possible. All CH Precision components contain sophisticated power supplies with extensive local DC regulation. But this is one field in which you can never put too much protection between the signal path and the noisy, RF polluted and mechanically intrusive AC supply. The X1 is an optional power supply for the C1.2, D1.5, L1, and P1. The X1 can be fitted with single or double regulators which powers up to two components without performance sacrifice. It is recommended the dual regulator power up only digital or all analog sources.
  • The I1 is supplied in standard form equipped with four digital inputs (CH-Link HD, AES/EBU, S/PDIF and TosLink – although a second identical digital input board can be added in the spare chassis slot if you need the extra connections) one set of balanced and two pairs of single-ended analog inputs. The factory fitted Ethernet Control Board, which allows the unit to be remotely accessed, configured and controlled via the CH-Control Android App, can be replaced with a full network streaming capable Ethernet input and a separate, asynchronous USB input card can be added to enable connection of computer sources for file replay. The discrete, fully-complementary analog input boards can be fitted with additional internal circuit blocks that allow owners to convert either or both of the RCA analog inputs into current-sensing MC phono-inputs, complete with switchable replay EQ settings for RIAA, eRIAA, Decca, Columbia, EMI and Teldec (DGG) curves. Finally, a Clock- Sync board allows you to slave the I1 to external master clocks, or designate its internal clock as the system master. Dominating the interior of the I1 chassis, you’ll find a massive 1000VA transformer that’s more than capable of supporting the 100 watt/channel into 8 Ohms rated output; in combination with the 100,000uF of reservoir capacitance it allows the output stage to handle awkward loudspeaker loads with ease.
  • Faced with exactly the same challenges as the M1.1, the A1.5 embodies the same sophisticated, modular and scalable approach. It might be (slightly) smaller than the M1.1 and around two-thirds of its weight, but it’s still four amplifiers in one. It still offers the same adaptable, software controlled topology, adjustable input configuration and gain, user selectable global feedback ratio and cost-effective upgrade path. It offers exactly the same, incredibly short signal path, fully discrete, fully balanced and fully complementary circuit, built with the same carefully selected components to the same exacting standards. Even the casework, although shorter, has the same footprint, uses the same construction and includes the same mechanical grounding/stacking system. In fact, in every important way, the A1.5 is, quite literally, an M1.1 writ small – or, in Hollywood terms, “Honey, I shrank the amp…”.
