Short answer: the Audioengine A5+ Classic. It ranks #27 of 67 powered bookshelf speakers by sound quality, rated 4.0/5, at $399. The Palmer STUDIMON 5 ranks #44, rated 3.6/5, at $350, $49 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Audioengine A5+ Classic: ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. The tradeoff: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments.
The case for the Palmer STUDIMON 5: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. The catch: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend.
Buy the Audioengine A5+ Classic. It is rated higher for sound quality, and the $49 saving on the Palmer STUDIMON 5 is not enough to make up the difference.

Audioengine A5+ Classic: $399.00 per pair Amazon B&H Photo Video eBay
Pros: ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. The analog powered pair is straightforward to use without an external amplifier. The measured result supports a more capable tonal balance than its former low position suggested. Measured bass extension of 68Hz (-3dB).
Cons: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments. The existing review reports crossover-region directivity errors and a distortion feature around 800-900Hz. The score does not make it a reference monitor, and adding a subwoofer cannot correct those midrange and off-axis issues.

Palmer STUDIMON 5: $350 per pair Thomann eBay
Pros: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. Balanced inputs and a conventional compact monitor cabinet make it straightforward to use with studio equipment. The broad response trend is approximately level rather than strongly bright or dark.
Cons: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend. There are no room-EQ controls to address broad placement errors, and the available score does not establish clean output.
