In 2014, we profiled a Kickstarter success story for an audio product known as The Vamp. Simply put, The Vamp was a self-contained, single-channel amplifier that let you transform any speaker into a wireless Bluetooth speaker system.

Aside from serving as an alternative to self-contained speakers, The Vamp gave people a reason to hang on to old (vintage) speakers that might otherwise end up as electronic waste in a landfill.

Having sold more than 10,000 units since launching two years ago, the team is returning to Kickstarter in hopes of funding a successor to the original device as well as a brand new product.

The Vamp Stereo, as its name suggests, accommodates two speakers for stereo sound for more than 10 hours on a single charge (rechargeable via micro USB cable). It also comes with a magnetic metal disc that allows you to mount The Vamp on the side of a speaker. Its creator, Paul Cocksedge, says it has "twice the sound" of the original and uses the latest Bluetooth technology although unfortunately, the amp's power rating isn't mentioned (FYI, underpowering a speaker won't damage it as myths have led many to believe).

If you don't have an old speaker or two to use with The Vamp Stereo then you may be interested in The Vamp Stereo + Speaker.

The Vamp Stereo + Speaker is essentially a speaker box with a cutout for The Vamp Stereo. Offered in black, white and natural color schemes (think plywood), the box measures 340 (L) x 200 (W) x 130 (H) mm and weighs around 4.6 pounds. Interestingly enough, users can connect two additional speakers for even more audio although again, it's unclear how much power the device is capable of.

The Kickstarter campaign is seeking to raise just shy of $130,000 to bring the two products to market. Those interested in backing The Vamp Stereo and The Vamp Stereo + Speaker will need to part ways with around $52 or $92, respectively.

There's also a third option, a speaker "totem," that's only being offered during the Kickstarter campaign. Described as a "beautiful sculpture," the totem aims to project sound to different corners of your room. It doesn't come cheap, however, as the silver-tier with two speakers will set you back about $995 while the top-tier, bespoke totem with three hand-picked speakers can be yours for roughly $1,990.

As of writing and with 16 days remaining, the campaign has raised more than $71,000 from close to 900 backers. If funded, backers can expect to receive their goods come March 2017 (two months earlier than initially advertised).
