MEET THE EA30 SERIES
Power, performance, and practical new features
At the heart of our headphones lies a meticulously engineered planar magnetic driver. This advanced technology ensures unparalleled phase coherency and an ultra-fast transient response, reproducing music with breathtaking realism, accuracy, and detail.
Tech Highlights
The EATA30 Pro features Topping’s proprietary NFCA(Nested Feedback Composite Amplifier) technology. This particular implementation utilizes 10 pcs of OPA1656 op-amps. In conjunction with the UHGF (Ultra High Gain Feedback) topology, this ensures an ultra-low noise floor, where noise levels are recorded as just 0.3µV, which translates to a THD+N of 0.00006%.
I/O
Inputs include both a single-ended RCA and a pair of 3-pin balanced XLRs. In the rear panel, there are 2 other pairs of outputs, which are pass-through outputs, not to be mistaken for pre-amp outputs.
The pass-through outputs are connected to its corresponding input, meaning RCA to RCA, and the ¼” balanced to the 3-pin XLR inputs.
While they are pass-through outputs, they are cut off when the headphone amp section is active, and only activated once the A30 Pro is switched to the off position. So this would work great with a setup that has both a headphone setup and active speakers since the headphones won’t be playing at the same time as the active speakers
Power
With power on the A30 Pro listed as 6W into 16Ω and 840mW into 300Ω, it can easily power most of full-sized headphones
