Influencer Sound Opinion: Z Reviews |
“How good is the TOPPING A90? Fucking good. Fucking real good.” “This beats [the THX 789] on paper. There is at least a transparent difference between [the A90] and [the THX 789].” “I really like this amplifier. It really does all that crazy bullshit it’s talking about.” |
“If you’re a THX fanboy, this is the best THX amplifier I’ve ever heard.” “It’s worth its cost. That’s all I gotta say.” “If you’re looking for $2,500 benchmark amp performance for $630, there you go.” “The A90 is still the $500 choice. This is a comparable choice...but I like the analog controls of the A90 better.” |
