Natural PWM-Type Digital Power Amp That Reproduces High-Resolution Sound Sources with Remarkable Purity

 

In order to vividly portray absolutely everything in various high-resolution sources; from the nuances in the most delicate performances to the highest energy-filled dynamic musical passages, Yamaha has built into this amplifier a digital power amplifier that outputs up to 70 watts per channel and features powerful drivability. Natural PWM type digital modulation with an extremely simple circuit configuration provides both natural, uncolored sound quality with higher efficiency. The low-pass filter of the latter part of the power amp, which significantly influences the sound quality, is a large coil made of low-loss, low-distortion OFC (oxygen-free copper) wire material. This simultaneously maintains the purity of high-resolution sound sources, while enhancing the power of the bass and ensuring warmth in the mid and high-frequency sounds. This delivers the best quality sound reproduction that is rich in musicality. This amplifier also features a Pure Direct switch that bypasses the tone / balance controls and a back buffer amp to improve the purity of sound as well.

DSD 5.6 MHz and PCM 384 kHz Playback with High-Grade USB DAC Functionality

Built into the unit is an exceptionally high-grade USB DAC which can reproduce high-resolution sound sources with all their original quality. It is compatible with native playback of DSD 5.6 MHz (DSD128) or 384 kHz / 32-bit PCM which records music information with extraordinary detail by sampling up to a massive 5,644,800 times per second. The D/A converter is the high-performance SABRE32™ (ES9010K2M) from the U.S. company, ESS Technology, and its USB device controller IC is from the latest product from XMOS®. By restricting shutter noise through asynchronous transference, this delivers pure reproduction and optimum sound quality.

Fully Enjoy the Quality of High-Resolution Sound Sources with Your Favorite Headphones

Another major benefit of the A-U671 is the availability to use it as a high-quality headphone amplifier. With the USB DAC function, mixed with its internal high-performance D/A conversion, high-resolution sound sources will sound their purest.

Yamaha Factory Refurbished

Buying a Yamaha Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with all original accessories included. When you consider that a factory-renewed Yamaha product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is, in many ways, better than new. And for your piece of mind and protection, your purchase is covered by a manufacturers warranty valid at any authorized Yamaha repair center (you can look-up locations online here or call 714-522-9888)

Yamaha, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Yamaha certified technicians, where they are fully tested, repaired (only if necessary), and tested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Yamaha Factory Refurbished" product.

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our inventory.
