For sale is my Little Dot I+ headphone amplifier, which has seen only light usage.
Purchased from Little Dot in August 2010, it's in perfect working order and excellent condition. Feel free to fire me any questions - higher res. photos can be supplied on request.
Shipping cost to be determined dependent on location. Any shipping cost will be no higher than the courier charge. I'm happy to be flexible as to courier of choice, so long as some method of recorded delivery/tracking is used. The headphones will be shipped in appropriate packaging.
PayPal only.
I'm also selling my Grado SR225i headphones - please check out the listing. If you purchase both items I'll reduce the price of each by 5% (and combine shipping of course). This amp is a popular choice with Grado headphones on account of providing the sound of tubes with a solid state output stage (better for low impedance headphones like Grado's).
Thanks for looking!
Manufacturer's Description
The Little Dot I+ is a hybrid transistor-vacuum tube headphone amplifier, which combines the smooth, musical sound of tubes with the high output current of transistors. The vacuum tube stage is run in Class-A, the MC33078 operational amplifier (socketed) provides voltage amplification, and BD139/BD140 transistors serve as output buffers. The Little Dot I+ is specifically designed and optimized for driving low impedance headphones that require high current to perform to their full potential. Depending on how the switches are configured, three different families of vacuum tubes can be used (EF95, EF92, and 408A). With two gain settings and DIP switches for vacuum tube rolling, the Little Dot I+ offers versatility and incredible sound quality in a tiny footprint!
