Heresy IV Overview

A Little Heresy Is Good For The Soul.

Because of its size, the Heresy IV offers the greatest degree of placement flexibility in the Heritage series. First introduced in 1957, this three-way horn-loaded loudspeaker is still able to deliver the awe-inspiring KlipschKlipsch sound that our fans around the world know and love.

DESIGNED & MADE IN THE USA
The Klipsch Heresy IV speaker is a testament to the quality that Klipsch demands from each and every one of its audio products. Remember great sound? We do, too. The Klipsch Heresy enclosure is made in the USA, by proud craftsmen in Hope, Arkansas, just like Paul W. Klipsch (PWK) intended.

COMPACT, THREE-WAY LOUDSPEAKER
The Heresy was originally introduced in 1957 with a compact three-way design utilizing a 12” woofer and horn-loaded midrange and tweeter. In 2006, the Heresy III was upgraded with a more powerful woofer and a bi-wire network as well as midrange and tweeter compression drivers and features a titanium diaphragm for smooth and accurate definition.

DRIVERS
The Heresy IV incorporates an all-new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702 midrange is mated to the K-704 Tractrix® horn, providing you with a wide coverage pattern and smooth response throughout the listening area.

The K-107-TI titanium diaphragm high-frequency driver features an all-new wide dispersion phase plug, providing exceptionally even high-frequency dispersion throughout the listening area, making for a wider, more accurate sweet spot.

NETWORK
The Heresy IV has been completely revoiced from its predecessor, utilizing premium componentry in an all-new high-fidelity network — minimizing electrical degradation throughout the circuitry — for truer to life sound with best in class efficiency and power handling. The new network draws from the classic three-way steep slope design of the legendary Klipschorn, La Scala, and Cornwall speakers.

TRACTRIX® PORTS
For the first time in its long legacy, the Heresy now features a rear port – improving low-frequency extension by almost 10Hz, for room-filling bass. Utilizing Tractrix geometry, the all-new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom-designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.

BI-AMP INPUT PANEL AND BINDING POSTS
The Heresy’s premium, aluminum input panel accommodates large, high-quality speaker cables. Strong, versatile, and quality binding posts provide the capability for bi-wiring or bi-amping. The quality continues with Audioquest Type 4 with Star-Quad Geometry internal wiring featuring carbon-loaded insulation, nitrogen-injected PE, and solid long-grain copper conductors ensuring the purest signal transfer from the input cup to crossover network to drivers.

MA252 Overview

The MA252 2-Channel Integrated Amplifier is the first hybrid integrated amplifier from McIntosh. Taking retro design cues from the legendary McIntosh MC275 Vacuum Tube Amplifier, the MA252 combines the best of vacuum tube and solid-state circuit design to create an amplifier that’s both visually and sonically stunning.

"The McIntosh MA252 offers an alluring combination of tube romanticism and solid-state resolution and authority... The ability to connect the listener to the music makes this tube-solid state-integrated a special component by any standard. I could happily listen to the MA252 for a long, long time." - PartTimeAudiophile

"If you’re looking for a definition of a ‘musical’ sound, the MA252 is it personified." - Audio Esoterica

The preamplifier stage uses two 12AX7a and two 12AT7 vacuum tubes housed inside stylish protective cages; the output stage is a direct coupled solid-state amplifier that delivers 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers. An all-analog design, it comes with 2 unbalanced, 1 balanced and 1 Moving Magnet phono input for turntables. All 4 inputs can be given user-friendly names in order to simplify user control. Bass and treble tone controls help fine-tune your music to your personal preferences. A full range subwoofer output is included for use with a powered subwoofer to further enhance low frequencies.

"Carved like a boat designed to surf all the waves of music." Listening to it proved it to be "fast, powerful, precise... but without losing the sublime McIntosh charm." Presented with ON Magazine Top Audio Award. - ON Magazine

A "beautifully designed amplifier" with a "relaxing approach to the music, but still it plays with control and power." It is "pure pleasure for the ears." Awarded 5 Stars. - Stereo+

The MA252 Integrated Amplifier features our McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors. These transistors eliminate the typical amplifier warm-up time so that the MA252 is in peak operating condition from the moment it’s turned on. A powerful control microprocessor is used for smooth system operation, along with some of the latest audio-grade circuit components that deliver the best possible sound.

Thanks to its solid-state output, the MA252 is our first product containing vacuum tubes to include our patented Power Guard® technology. Power Guard monitors the output signal for signs of overdriving and makes real-time micro-adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers. If Power Guard is activated, the 2 vacuum tubes connected to the affected audio channel(s) will flash an amber color; they will return to their normal green color when the clipping has stopped.

"The MA252 is a component worthy of consideration as the core to an audio system that will allow the user to listen for hours without fatigue. And, based on McIntosh's reputation for long-term reliability and service, possibly listen for decades." - Stereo Times

Other McIntosh technologies found in the MA252 Integrated Amplifier include Sentry Monitor™, High Drive headphone amplifier, and gold-plated speaker binding posts. Input selection, bass, treble, tone bypass, balance, and input offset levels can be adjusted using the front panel knobs or the included remote control; all settings and input selection will be shown on the OLED display. The entire unit sits atop a beautiful polished stainless steel chassis with a classic McIntosh-styled die-cast aluminum name badge attached to each side.

RS250A Complete HiFi Network Streamer Overview

The new RS250A features an upgraded DAC, opamps and word clock. The chassis gets an upgrade too, as it is now available in silver or black. With a large touchsreen display, terrific user interface, and the ability to operate the RS250A with a remote one can fully configure and operate this network music streamer without a tablet or phone. The RoseApp is available for iOS and Android devices, and is also super intuitive to use. There are a ton of features and connectivity options with the RS250A as well. One can use it as a streaming DAC with volume control, driving a pair of powered speakers, or monoblock amps. Or use your own preamp for a full analog volume control. Last there is the option to use the RS250 as as a streamer only, keeping one's existing preamp and DAC in the system.

The Streamer
The streamer can connect via Ethernet or Wi-fi. It has a powerful Hexa Core CPU with an Android based operating system. This also means you have compatibility with Android AND iOS devices. One can add up to 4tb of internal storage, connect an external drive via USB, or access your music library on your home network's NAS.

The DAC
The RS250A uses a new DAC and clock with proprietary processing that offers a low-noise, low-distortion, ultra-high-resolution sound with rich analog density. Sampling rates go up to PCM 32bit/768KHz and native DSD512 (22.5792Mhz). In addition, there are 5 filters one can choose from for tailoring the sound to one's individual preference if using the Ethernet input. The USB input is limited to just one filter however. Additionally, oversampling can be implemented as well if desired.

Linear Power Supply
The RS250A is designed with a low-noise toroidal linear power supply. Something that is difficult to find at this price point.

Flexibility
One thing we found very interesting about the HiFi Rose products is the ability to set the analog output voltage. There is of course the variable setting if one wishes to use as a volume control. But there are several fixed settings one can use to optimize the gain for ones preamplifier or amp.
