Bought these around 5/1/2022. Already have the Swans D1090 and Edifier S2000mkiii. Have two rooms, a 200 sq/ft office and a large living room with 20 ft ceilings. While the Edifiers sound great in the office, the D300's simply feel too powerful (if there is such a thing). But the Edifiers fail spectacularly in the living room, while the D1090's perform well in either. That was until we bought a piano which crowded the placement and caused bass resonances at mid-high volume. The D300's are indifferent to poor placement. They project a wider sound stage, deeper bass and more top-end detail than the D1090's - and do so at any volume - way more than I would care to listen to. Out of the box, the ribbon tweeters are too hot and "sharp" sounding. But they can be dialed down a db or two while still retaining excellent detail. They also have a rather high crossover at 3k. This results in a thinner low-high/upper-mid than the D1090's, sounding a bit less lush at times, while accentuating the sense of spaciousness & openness. Ultimately a 3-way system like Swans M300mkii would perform even better in the mid-range, for 50% more in price. But a 300W 2-way with ribbon tweeters and startling bass extension, bi-amped in attractive enough cabinets...?? If you want to fill a large room to audiophile standards, and can only part with around $500, then you can research this to death (highly recommended as there's some great content out there), only to conclude same as I that there's nothing even close to the D300's - save for the D1090's.
