Reviews and user comments


Part Time Audiophile

"Pardon me, but the A1’s got some balls... it sounds like a desktop amplifier; it has a sonic presence and detail much larger than its physical size and appearance might lead the listened to believe."

"The BEST portable rig I have ever heard."




- Michael Mercer, Audio 360


Digital Audio Review

"The A1 really likes to flex its musical muscles. This doesn't just mean that the Glove A1 plays louder than its rivals but that it also takes better control of your headphones' drivers, which in turn translates to superior rhythmic propulsion as well as more obvious separation. And whilst it's impossible to know how close the Glove's take is to the original performance, it connotes accuracy as a sensation: clean, crisp, and detailed.

Goodman's Glove is bang on the money for electronic music's clean lines and rhythmic urgency"




- John Darko, Digital Audio Review



"A far greater sense of texture and the space the recording was made in. Also far greater micro details but not at the expense of warmth or that lovely analog sound we all crave. That's with the T5P's. What's amazing though is that my first generation LCD2's running balanced don't sound dark anymore, it's like the glove has removed veils from them, never thought that would be possible!"




- Ian Dixon, Early Customer
