Short answer: the PSI Audio A21-M. It ranks #19 of 68 powered bookshelf speakers by sound quality (rated 4.5/5); the Meyer Sound Amie ranks #38 (rated 4.2/5).
Why pick the Meyer Sound Amie: ASR measured a 2.1dB response span from 300Hz to 5kHz and a 6.99 ideal-subwoofer score, supporting reasonably even midrange balance. Watch for: Measured -3dB extension is 48.3Hz, so full-range monitoring benefits from bass support.
The case for the PSI Audio A21-M: ASR measured 39.6Hz -3dB extension and a 2.2dB response span from 300Hz to 5kHz, giving useful bass and broadly even mids. The tradeoff: The measured tonal result is good rather than a clear advance over less costly competitors.

Meyer Sound Amie: $8,200 per pair RSPE Audio Solutions eBay
Pros: ASR measured a 2.1dB response span from 300Hz to 5kHz and a 6.99 ideal-subwoofer score, supporting reasonably even midrange balance. Its professional nearfield design is suited to a deliberately configured monitoring system.
Cons: Measured -3dB extension is 48.3Hz, so full-range monitoring benefits from bass support. The broader response and off-axis measurements are less even than the strongest competitors despite the narrow midband span. Professional installation features add cost without guaranteeing a tonal advantage.

PSI Audio A21-M: $7,440 per pair B&H Photo Video eBay
Pros: ASR measured 39.6Hz -3dB extension and a 2.2dB response span from 300Hz to 5kHz, giving useful bass and broadly even mids. Its 7.72 ideal-subwoofer score supports serious monitoring, with analog phase compensation offering an alternative to DSP-based systems. Measured bass extension of 39.6Hz (-3dB).
Cons: The measured tonal result is good rather than a clear advance over less costly competitors. There is no built-in automatic room-calibration system, so placement or external correction still matters. The premium construction and analog circuitry should not be mistaken for proof of better audible performance.
