    Riverstone Audio - Tested/Matched Pair (2 Tubes) 7-Pin GE JAN 5654W Fully-Tested Vacuum Tubes - Upgrade for 6AK5 / 6J1 / 6J1P / EF95 - GE 5654W Platinum Grade Pair

    • The mangi lacks good bass response and the Little Dot MK II does as well because it's a tube headphone amp
    • Greater bass response, no loss of detail (than the stock tubes), and everything is a bit clearer, broader frequency response
    • I can get great bass response from either headphone amp which is great
    • The original tubes sounded dry and lacked dynamic range, but these make everything sound more natural and improve bass response as well.
