"100% a Buy!" - Zeos Pantera, Instagram, CanJam NYC 2023 The world's first DAC +Amp + Headphone stand The unique design of the EF600 serves more than aesthetic purposes: it's also a functional headphone stand. This space-saving feature allows you to stow your favorite pair of headphones directly on the EF600, eliminating the need for a separate headphone stand. R2R Ladder DAC Unlike most DACs on the market, which use "Sigma" D/A chips from companies like ESS and AKM, the EF600 uses a "ladder" method to convert the digital signal from your computer into the analog signal you hear in your headphones. This approach uses an array of highly accurate resistors for tremendous musicality. HD Bluetooth With Bluetooth, wirelessly connect a phone, laptop, tablet, or streamer to the EF600 and enjoy hi-def codecs like LDAC, which deliver lossless sound reproduction for audiophile-grade sonics. RCA + XLR inputs Connect a turntable, CD or SACD player, and enjoy the EF600 as a high-performance headphone amplifier that's fully compatible with most players via RCA and XLR. Massive 5W per channel output power Power will never be a problem with this DAC/Amp. Delivering 5 watts per channel @32Ω, the EF600 can drive the vast majority of low-efficiency planar headphones, including the HIFIMAN Susvara. Balanced + S/E outputs You'll find four balanced outputs on the front panel: 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, and XLR four-pin balanced.

The FiiO BTR7 is a faithful and thrilling upgrade to the BTR5 Bluetooth DAC/Amp. It boasts its predecessor's fully-balanced dual-DAC-and-amp architecture, and adds a number of excellent quality-of-life improvements, like a color IPS display and wireless charging. Radiant color IPS display The laminated aluminum alloy body is optimized for comfort and ergonomics. It's paired with a 1.3" IPS color display that is the showpiece of the BTR7. The display features a brand-new colorful GUI that organizes information with an intuitive hierarchical design. Powerful high-performance DAC In each of the left and right channels of the BTR7 is the ES9219C, which is paired with a low-pass filter and an amplifier in a highly-optimized audio architecture that captures every last detail and dynamics of your music. Extraordinary and bold THX amplifiers The BTR7 is the first portable Bluetooth amplifier to utilize two THX AAA-28 amplifiers. Thanks to a design breakthrough, the FiiO R & D team was able to fit four channels of the THX AAA amplifiers into the BTR7's compact body for a fully balanced audio design. The result is 88% more single-ended power output and 30% more balanced power output compared to previous designs. Wireless freedom The Qualcomm QCC5124 Bluetooth chip, with its dual DSP and dual-core CPU architecture, ensures a stable connection and supports high-res formats like LDAC/aptX HD/aptX Adaptive and more common formats like AAC/SBC. XMOS XUF208 control chip When used for USB Audio, the BTR7 uses the XMOS XUF208 chip to receive and decode audio data streams, with support for PCM 384kHz and native DSD256. Wired + wireless charging As a multifunctional Bluetooth amplifier, the BTR7 needs plenty of battery power when used throughout the day. Not only has the battery capacity been increased to 880mAh, but both wired and wireless charging support allows you to charge in more scenarios. USB wired charging is fast and efficient, while Qi wireless charging is convenient and will automatically stop charging when the battery is full. One-click dongle mode The BTR7 can be used as a wired decoder and headphone amplifier for your phone. Simply press the "CHARGE" button with one click to switch into and out of dongle mode. Compared to the typical dongle, the BTR7 does not consume your phone's battery power.

A new baseline for balanced sound The K7 has a six-stage audio circuit with truly balanced analog and digital sections, which helps to reduce crosstalk and reproduce music faithfully and noiselessly. Balanced amplification couldn't sound better Using the same THX AAA 788+ amplifiers as the K9 Pro, the K7 is capable of outputting 560mW into a 300Ω load at 1% distortion, and 200mW into a 32Ω load at 1% distortion. This ensures both low and high impedance headphones are fully powered with optimal musicality. Dual AK4493SEQ D/A chips The left and right channels are each equipped with an efficient high-performance AK4493SEQ D/A chip. These 32-bit D/A chips support 768kHz PCM and DSD512, ideal for high-resolution audio source playback. RGB indicator lights The RGB indicator lights are capable of displaying single colors as well as mixed colors, with a unique light flow effect during power on/off or input switching. Worry-free listening Overheating, overload, and DC protection systems ensure that the K7 always operates at its best, so you can always enjoy a worry-free listening experience. Multiple independent power stages The K7 features a power design consisting of multiple independent stages, with the voltage of each stage regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply. All in all, the K7's power design supplies plentiful, clean power for an extraordinary listening experience. Smooth operator The K7 features an all-aluminum alloy construction, carefully finished with CNC and other processes. Its elegant black color is perfectly complemented by the gold accents of the THX and Hi-Res Audio badges and the splashes of color from the RGB lights. Precisely-tuned volume Thanks to its ADC curve reconstruction, the volume potentiometer features 112 smooth steps of adjustable volume free of channel imbalances and noise. Space-conscious design The K7 features a space-conscious design that only measures 2.1 inches thick and with a footprint smaller than ⅓ of an A4 sized sheet of paper-allowing it to fit snugly on even small desks.
