GUSTARD just released their first headphone amp, H10 this month and yet have any review from users.
But Gustard have made a good effort for their DAC , x10 & x9 3rd generation. And it would be no doubt for another high cost efficiency product.
The Gustard H10 uses 2 high quality transformer and each power supply response for either left or right sound channel. The high power transformer can reduce the 2 channel crosstalk. The H10 having RCA and Balanced XLR input and output as 6.35 jack.
Price is US$394.90 and available from Kidult Online
