Short answer: the JBL 305P MKII. It ranks #11 of 58 powered bookshelf speakers by sound quality at $319; the Topping MA4 ranks #33 and costs $449, so there is not much of a tradeoff to weigh.
What the JBL 305P MKII offers: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression. Watch for: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.
What the Topping MA4 offers: Topping’s first loudspeaker, notable for deliberately skipping the DAC and DSP the company built its reputation on. A single balanced XLR input feeds a fully analog crossover, which Topping argues keeps the signal path free of extra conversion stages. The bass alignment measures a low Q of 0.452, rolling off cleanly rather than peaking, and extension reaches 49.8Hz at -3dB for a compact 4 inch two way, at a genuinely low price. Watch for: On axis deviation measures 0.503dB average, on the rougher side for this catalog, and listening window smoothness sits at a moderate 0.44. No USB, Bluetooth, or digital input of any kind, an unusual limitation from a DAC company and a real constraint if you want a simple all in one desktop setup. This is Topping’s first speaker with no track record in the category, and current US retail availability is limited, most confirmed stock is through European or Indian resellers.
Buy the JBL 305P MKII. It ranks higher for sound quality than the Topping MA4 and costs less, so there is no real case for the other one.
