Desktop Valve Amplifier catches the eye and ear

[ad_1]

The devil is in the detail, of course – and I’m no audio expert – and this is on KickStarter, which is American English for “Caveat Emptor”…

However, New Zealand’s IMS Electronics already has a track record in this area and the Desktop Valve Amplifier is an amplification of existing work…

Check out the Kickstarter page, the full specs and admire the images! The unit is built around Raytheon 6418 Glass Tube Valves, the Savi Audio SA9227 audio streaming controller (described as compatible with all Windows operating systems and Apple OS) and the Texas Instruments PCM5102A audio stereo DAC.

As well as the eye-catching innards, aluminum casing and Gorilla Glass complete the 140 x 120 x 25 mm package.

Additions to their previous Kickstarter project (the Hybrid Valve Headphone Amplifier) include a 100 Watt speaker amplifier. There are also two headphone jacks (6.5mm), each with their own volume controls, so two people can listen in together.

Saviaudio’s SA9227 and Texas Instruments PCM5102A are at the heart of our extremely hi resolution DAC valve amplifier (32bit/384kHz). Combined with the military spec Raytheon valves and award winning Burr Brown series OPA2134 amplifier chip, this combination produces extremely hi quality audio with extremely low noise and distortion.
