The world's first high performance full balanced discrete class A headphone amplifier by Eleven Audio TM combines smooth detailed sound with the noise free black backgrounds. Amazing low level detail, smooth very real mids and vocals, and clear highs only begin to describe how good this amp is!

Internal user replaceable batteries dramatically reduce AC line noise to negligible levels. This amp will run for hours without AC power, or plug in for continuous play, with the same highly refined sound on either power source. Circuitry is designed to float the batteries on the mains at all times for pure clean sound.

Accepts only balanced XLR L/R channel inputs. Four channels of amplification straight through to a high performance balanced headphone connection with 1.5 full watts of super smooth sounding class A bias amplification. DC coupled means huge low frequency bass resolution, the Broadway sounds way larger than it looks and can drive nearly any power hungry headphone with ease.

Specifications:

  • Frequency Response: DC-100 KHz
  • Power: 1.5 watts @ 32 ohms fully balanced class A operation (amplifier biased full on at all times, no edgy crossover distortion typical of other amplifiers)
  • Signal to noise ratio 130 dB
  • Run time: Approx. 6 hours on full battery, indefinitely while connected to the external AC power supply
  • Inputs: Stereo balanced 3 pin XLR's only
  • High quality volume adjust potentiometer
  • Headphone Outputs: 4 pin balanced XLR and 4.4 mm Pentaconn
  • Batteries: Replaceable Li Ion 18650 x 4 batteries add to power supply filtering
  • AC Charge adaptor: 100-240 VAC, 50-60 Hz. (Unit has built-in battery management, auto-off on low battery, auto charge). Requires a standard grounded IEC C13 style AC cord (not included)
  • Dimension: 8.3 in W x 6.1 in D (plus volume knob) (212 mm L x 156 mm D, 190 mm including volume control), 1.9in / 48 mm H
  • Weight: Approx. 1150 grams with battery

HIGHLY RECOMMENDED for our ABYSS Diana headphones

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
