Check out Fyne Audio F500, should be a great pairing with E-280. There is a lightly used pair on sale for $850. My all time favorite bookshelf speaker is TAD Micro Evolution One (ME-1) but that may be out of your budget.
Accuphase Bookshelf Speaker Pairing recommend
Friends: I would love a bookshelf speaker suggestion: I have come into a used Accuphase e-280 integrated amp which I will use for streaming music in a small den (11 x 11 ft / 3 x 3 meters). I now need to buy bookshelf speakers: I would love speaker recommends from knowledgeable folks here. I prefer warm rich tones, detailed and controlled, leaning toward feeling like "live". . I already have a good subwoofer. I appreciate your time. Thank you.
