The I1 integrated amplifier is possibly the most complex project that CH Precision has ever undertaken – and the most versatile product we have ever produced. Imagine the core qualities and capabilities of the C1.2 DAC Controller and A1.5 Amplifier combined in a single box. Now throw in the choice parts of the L1 Line-stage and add the option of a P1 phono-stage, all combined in a single, standard CH chassis and you begin to get the picture. 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. All digital inputs are fully MQA compatible, while our latest proprietary, fixed-point PEtER spline filtering and updated DSP deliver accurate and musically natural digital decoding. 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. How did we pack so much functionality into a single chassis? By leveraging the power of sophisticated software control, modular construction and advanced digital processing. The I1’s volume control is a remarkable hybrid design, that uses an R-2R resistor ladder in the analog domain for setting coarse levels, with fine adjustment taking place in the digital domain, a combination that allows incredibly precise level control without eroding bit depth, resolution or dynamic range. Likewise, the I1’s advanced analog-to-digital conversion stage allows us to set overall cartridge gain and replay EQ in the digital domain, providing unparalleled phono replay flexibility, accuracy and features in an integrated unit. You mean we turn the analog inputs into digital? Yes – but if you don’t tell your friends they’ll never know. Indeed, many listeners swear that the I1’s phonostage delivers some of the finest analog sound they’ve ever enjoyed! Which tells you that its digital replay is pretty impressive too… Features AES/EBU, coaxial S/PDIF and optical TOSlink digital inputs I2S proprietary CH Link HD digital input Balanced XLR and single-ended RCA analog inputs Current-sensing RCA phono input, ideal for MC cartridges, RIAA, eRIAA, Emi, Columbia, Decca and Teldec EQ curves, optional RJ-45 Ethernet audio input, UPnP, Tidal, Qobuz and Web radio compatible, optional USB class 1.0 and 2.0 audio input for direct connection to a computer, optional Proprietary CH-PEtER synchronous spline-based data upsampling, converting any incoming audio stream to DXD resolution Resolution enhancement for audio material of less than 24 bits Two ultra low jitter digitally controlled VCXO oscillators, one per time domain Individual multibit Delta-Sigma converter per channel Pure class A, fully symmetrical analog design Fully discrete, ultra low noise, high slew rate design Hybrid digital and analogue volume control Tight tolerance high-grade metal film resistors 120dB range in 0.5dB steps Volume pre-trimming on each analogue input Phono input adjustable gain Post volume control stereo balanced line-level analogue outputs Pure class A ultra low noise driver and class AB pure follower power stage Feedback Ratio adjustable from 0% – local feedback only – to 100% – global feedback only – in 20% steps ExactBias circuitry Power transistors and heat sink temperature monitored No output relay Customized Argento loudspeaker binding posts Shielded 1000VA power transformer Hyper fast soft recovery diode bridge rectifiers Total of 100’000uF reservoir and filtering capacitors Made in Switzerland Specifications Standard Inputs Factory fitted with CH-Link HD, AES/EBU, S/PDIF and TosLink digital inputs The CH-Link HD interface allows for synchronized transfer of high definition audio content (up to 32bit/768kHz) and DSD, offering the ideal interconnection to the D1.5 CD/SACD Transport or other CH-Link HD equipped units Standard digital inputs accept PCM to 24bit/192kHz, DSD 1bit/2.822MHz (DSD64 DoP encoded) Ethernet Control Board (replaced by the network streaming board if ordered or retro-fitted) Optional Digital Inputs The I1 can accept two digital input boards, allowing multiple digital sources to be connected.

The reference level McIntosh MC2.1KW Monoblock Power Amplifier is the ultimate power in home audio amplification. Our 75+ years of experience as the leader of sound reproduction has led us to the MC2.1KW. The pinnacle of audio amplification, the MC2.1KW stands as a testament to our unwavering commitment to sonic perfection. This tri-chassis marvel possesses the remarkable ability to deliver an astonishing 2,000 Watts of pristine McIntosh power, forever transforming your home stereo or theater experience. At McIntosh, we don't just appreciate sound – we are made of sound. The MC2.1KW is the embodiment of our passion, and it invites you to embark on an extraordinary journey through sound. Available separately or as part of our Reference Music System and Reference Home Theater System, the MC2.1KW pairs seamlessly with our XRT2.1K Loudspeaker or its predecessor, the XRT2K. However, its versatility knows no bounds and it's not limited to just being used with McIntosh speakers but instead can be used with a wide variety of other speakers. It is ideally suited for audio systems that have power hungry loudspeakers; systems located in extremely large rooms; or for audio enthusiasts who simply demand the latest and best in state-of-the-art home audio amplification. SYMPHONY OF TECHNOLOGY The MC2.1KW consists of three separate modules: one Output Module and two Power Modules that each contain a 1,000 Watt amplifier. The incoming audio signal enters the Output Module from the preamplifier. An in-phase signal is sent from the Output Module to one of the Power Modules and is amplified. At the same time, an out-of-phase signal is sent to the other Power Module and amplified. Both amplified signals exit the Power Modules and reenter the Output Module where they drive opposite ends of the bi-filar wound McIntosh Autoformer™. This combines the two audio signals back into one with the power summed while any noise is reduced or completely canceled. Through this artful engineering, a low distortion audio signal leaves the Output Module to deliver pristine sound through your speaker. Why are there three modules instead of one? There are two reasons. First is about practicality; each module weighs over 120 lbs (54 kg), so if it was just one module it would be very heavy (close to 400 lbs (181 kg)) and tough to move. With it being comprised of three modules, each is more manageable to move. Another reason has to do with the electrical wiring typically found inside homes. If the MC2.1KW was just one module, it would need to plug into a high voltage outlet (for example: the kind of outlet used by electric ranges in the United States). With it divided up into three modules, each can have a more common plug that works with the type of outlets commonly found in homes so that special wiring does not need to be installed inside your walls. A TRIBUTE TO 75 YEARS OF EXCELLENCE McIntosh celebrated our 75th Anniversary in 2024. To commemorate this milestone, the first 75 pairs of MC2.1KW sold through May 31, 2025 to each country McIntosh is distributed in will include special anniversary badging. The Output Module will have a dual anodized laser-engraved badge proudly displaying our 75th Anniversary logo on the top, while the handles on all three modules will have "75 years" engraved in them. These additions are sure to make every MC2.1KW built through May 31, 2025 a true collector's item for McIntosh enthusiasts. FULL POWER WITH NO SACRIFICES Thanks to our hand wound Autoformer, the full 2,000 Watts of power can be delivered into a speaker regardless if its impedance is 2, 4 or 8 Ohms. This means you won't need to sacrifice any power if your speaker impedance doesn't match the amplifier's output impedance. That's because amplifiers from most other brands only have one output impedance and if that doesn't match your speaker's impedance, then you could sacrifice up to half of the amplifier's power capabilities. This will not happen with our Autoformer and its unique ability to output full power at three separate impedances. A SONIC LEAP FORWARD The MC2.1KW succeeds the MC2KW, which rocked the Las Vegas convention hall – and the entire audio world – when it was introduced at the 2005 CES Show. The next generation MC2.1KW offers many sonic upgrades. Chief among them are substantially larger filter capacitors that improve the performance of low end frequencies as well as significantly improving dynamic headroom. These eight larger capacitors are located in the Power Modules behind the custom Power Bank that is visible through the front panel glass. Our patented Solid Cinch ™ speaker binding posts easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the posts are gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables. There are dedicated binding posts for 2, 4 and 8 Ohm impedances, with the connectors for each impedance rating located on a separate output platform on the back of the Output Module. Each output platform also has three sets of identical binding posts to facilitate bi- or tri-wiring your loudspeaker. Four of our McIntosh Monogrammed Heatsinks ™ are found on each Power Module. Made from high quality materials with excellent thermal conductivity properties and connected to advanced high current output transistors that eliminate thermal equilibrium lag time, these heatsinks maintain efficient heat dissipation, ensuring consistent audio quality from the first note to the last. Other upgrades include enhanced circuit designs with modern components and shorter signal paths; updated electrical wiring; bayonet IP68 rated interconnect cables that connect the three modules together; and direct LED front panel lighting. DUAL INPUTS FOR ADVANCED SYSTEM CONFIGURATIONS New on the MC2.1KW are dual sets of balanced and unbalanced inputs, conveniently allowing you to connect more than one preamplifier. This gives you the ability to easily switch between vacuum tube and solid state signals, such as from our reference level C12000 Solid State and Vacuum Tube Preamplifier that has outputs for both signal types, or from separate vacuum tube and solid state preamplifiers. Or use the second set of inputs to connect two preamplifiers of the same type, the choice is yours. The dual inputs on the MC2.1KW give you added system flexibility and lets you use the signal type of your choice depending on the type of music you're listening to and your listening preferences. TRUSTED MCINTOSH TECHNOLOGIES Our exclusive McIntosh technologies ensure your investment is protected and your experience flawless. Power Guard ® monitors the audio input signal coming into the amplifier and if it detects the amplifier will be overdriven, makes real time, near speed of light adjustments to prevent harsh sounding and potentially speaker damaging clipping. These adjustments are imperceptible to your ear so there is no degradation to sound quality. Sentry Monitor ™ is our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal. Quad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signal. Power Control to send power on/off signals to other connected McIntosh components (such as CD Players, turntables, tuners, and media streamers) for easy system power up and shutdown. WITNESS THE BEAUTY Crafted with stainless steel polished to a gleaming mirrored finish and immaculate metal casework, the MC2.1KW is a visual masterpiece. Black glass front panels, illuminated logos, rotary knobs, aluminum handles, and a responsive blue Watt meter complete the timeless design.

The Musical Fidelity M5si integrated amplifier is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. It has inputs for phono (MM), 4 line inputs and USB ‘B’ up to 24bit 96 kHz. With very low distortion, outstanding noise ratio and an extremely flat frequency response, it is configured as two independent monoblocs with a separate preamp, but all mounted on one pcb. Its technical performance is about equal to the M6si. The M5si produces an extraordinary sweet clear lucid sound. Significantly it was developed after our amazing legendary Nu-Vista 800. Consequently some of the Nu-Vista 800’s subtle pcb layout solutions have found their way into the M5si. And in turn those solutions stem from our legendary TITAN power amp. The Musical Fidelity Design-Philosophy Further flexibility is provided by the M5si‘s carefully considered connectivity, which includes 4 line-level inputs, a switchable home-theatre throughput, a USB input, a high quality MM phono stage and trigger in & outputs. When you hear it we are sure you will understand the relationship between the two. The M5si projects a deep and wide stereo image with very extended bass and a crystalline top end without a trace of harshness. Musical Fidelity NOW streams We’ve seen a surge in offerings from HiFi companies with all-in-one solutions, sometimes with big displays on top. Unfortunately, such developments mean that sound quality suffers. At Musical Fidelity, we acknowledge that any WiFi or BT circuitry generates a substantial amount of RF pollution and distorts analogue amp circuitry when incorporated into integrated, one-box solutions. Musical Fidelity stands for sound quality and robust design that lasts for decades. We INVEST our money and resources in top-tier hardware and the pursuit of optimal music reproduction. Robust mechanics - Discrete circuits - Huge transformers - Class A/B amps. No HF and RF distortion. We aim to have the best hardware and sound quality in every price range and make true high-end affordable. We are partnering with one of the best STREAMING SPECIALISTS - the US Californian high-tech company LINKPLAY. The M5si Stream includes a free WiiM Pro. The separate box and separate power supply ensure that we reduce RF and HF radiation and we can keep our analog amplifier technology as good as it is. LINKPLAY offers state-of-the-art technology, seamlessly compatible with any contemporary streaming service on the market, all navigable through an INTUITIVE and user-friendly APP.

The Musical Fidelity M5si integrated amplifier is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. It has inputs for phono (MM), 4 line inputs and USB ‘B’ up to 24bit 96 kHz. Internally, the M6si is configured as 2 independent monobloc power amps with a separate pre amp. It is, in fact, a pre amp with 2 monobloc power amps that just happen to share the same casework. It features technology trickled down from our legendary 1kW TITAN power amp. And the M6 combination of high power, high current and extraordinary stability means that it can drive any loudspeaker with ease.
