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

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

They work! Even if you hate socks
I am not a sock wearer. Can't stand having my foot entirely shrouded in cloth. I don't wear socks with my sandals, slides, clogs and other shoes most of the year. Only on the coldest winter days. I know, It's weird. So, with my sock phobia one thing that happens is your heals get dry and rough. I opted to try these because the toes are free. I barely notice the socks on my heels/ankles when my toes get air (outside of bedcovers always). I put good thick lotion on my heels and sides of feet. A little less on the toes so they don't stain anything. The silicone lining on the heel holds that lotion against the affected areas. In a couple days my feet felt soft and looked pretty. No cracks, no white roughness. They look pink and freshly spa-ed. Fit is good on size 9 feet with thickish ankles. Highly recommend.

Nice Socks, Bad Shipping
The socks are definitely worth the price. They are cozy and non constructive. They colors are nice. My only complaint is the method in which it was shipped. Slapping a mailing label on a clear bag is not acceptable. The shipper didn't consider protecting my privacy. I hate to think if it was something extremely private. Consumers deserve better when it comes to the content of their mail.
