About The Parasound Halo P6/A21+ Pre-Power Combo

The Parasound Halo P6/A21+ Pre-Power Combo combines pure quality and heavenly sound that stays true to Parasound’s mission, to constantly innovate and put great sound into stunning packages. Buying the two together will deliver more than just a saving of a few dollars in your back pocket, but will ensure you get a marriage made in heaven - well in a musical sense anyway!

Halo is Parasound’s premier line and completely designed in the USA.  Yes, they have incredible styling and have done so for decades. Good news is the 'beauty' is also behind that beautifully engineered front panel! Parasound Halo series products have a reputation for going head-to-head with some of the most expensive and often 'hand-made' reference equipment on the market but due to the savings of relatively small-run mass production, cost a fraction of the price. The sheer quantity of rave reviews and honours is unmatched and without precedent. In fact, many of Parasound’s Halo products are stereophile class A Recommended Components and have been for the past sixteen years. The P6 and A21+ is no exception! The P6/A21+ Combo contains quality design and plenty of features that are perfect for those wanting amazing stereo performance in a medium sized room.

Halo P6 Stereo Preamplifier: The Parasound Halo P6 is the perfect addition to any modern home stereo or home theatre system. The new DAC in the P6 helps widen your software playback options via two optical, one coaxial and a new USB receiver - now with plug-and-play support for Windows 10 in addition to Mac. The USB input inside the P6 supports PCM up to 384 kHz/32-bit, native DSD256, and DoP DSD bit streams. The coax and optical inputs accept PCM up to 192 kHz/24-bit.

Packed Full Of Features: The P6 is also perfect For Vinyl Lovers. The Halo P6 Comes equipped with a high quality phono stage that supports MM (The most common), MC and MI cartridges. You can select these through the new three-position load/cartridge selector switch. The high quality features continue with the inclusion of a quality current-feedback headphone amplifier in the P6. The clever design of this headphone amp helps prevent distortions that lead to listening fatigue. The amplifier can drive headphones up to 600 ohms. With plenty more features such as balanced and unbalanced subwoofer outputs, high-pass and low-pass crossovers, Burr-Brown Volume Control and Theatre Bypass inputs it’s a truly must-have stereo pre-amp.

Halo A21+ Power Amplifier: The new Parasound Halo A21+ power amplifier has been designed with the most advanced, proven class A/AB amplifier technology and is built to extremely strict quality and performance standards for which Parasound is renowned. Parasound decided to update their already brilliant A 21 power amplifier which had become a staple for their brand since around 2008 - almost 10 years which is. With the assistance of legendary Audio Designer John Curl, they’ve created a beautiful and powerful successor to the A21...the A21+ stereo power amplifier. Read on for more info.

Circuitry Designed By John Curl: Parasound design consultant John Curl has been a legend among audiophiles and electronic engineers for decades. He pioneered measurements to correlate musical accuracy with the materials used in parts, worked with world-class touring companies, has designed highly coveted audio classics, including the original Mark Levinson JC-2, Denneson JC-80, Vendetta Phono Preamplifier, and CTC Blowtorch preamplifiers; master recorders for Wilson Audio and Mobile Fidelity; and the mixing consoles used in live concerts by The Grateful Dead and the Montreux Jazz Festival in Switzerland.

As Parasound's featured amplifier designer since 1990, he has created many products that have earned Parasound worldwide acclaim, including the Parasound Halo JC 1, JC 2 and JC 2 BP, JC 3, JC 3+ and JC 3 Jr. and JC 5. John is particularly proud of what he and Parasound have accomplished together: “The circuits I design for Parasound are extremely sophisticated and are typical of products that are far more expensive. I can’t think of any other audio products that offer nearly as much bang for the buck.”

Parts Selection: Every part within the A 21+ is carefully chosen for its accuracy and reliability. Metal film resistors with 1% tolerance are selected for their precision and because their values don’t drift as they heat up during operation. Polypropylene and mica capacitors are used extensively for their superior linearity and low dielectric absorption. Semiconductors are selected for superior performance in their specific roles in the circuit. Gold has the best conductivity of any metal, so Parasound use high quality gold-plated input connectors and speaker terminals. The double-sided circuit boards are FR4 glass epoxy for long-term durability. The chassis is made of heavy gauge steel to safely house the internal circuitry. This attention to detail when selecting parts makes the difference between a very good amplifier and an outstanding amplifier.

The Power Supply: The heart of the power supply is a massive 1.3kVA toroid power transformer, chosen for its efficiency, low hum field, and high power rating. Encapsulating this massive power transformer in an epoxy-filled steel canister assures ultra-quiet performance. The A 21+ power transformer employs multiple independent secondary windings so that each amplifier channel has its own power supply, assuring more than ample DC voltage at all times and under all conditions. It also reduces inter-channel crosstalk that can blur the sound and impair the correct sense of where instruments, dialogue and effects are positioned.
