I am in the process of downsizing from large Dunlavy speakers with Levinson amplification to smaller floorstanding or bookshelf speakers with moderate power (35 watt EL34 or 40 watt KT88) integrated tube amplification. I don't need super high efficiency speakers, just efficient enough to be a good match for a tube amp. I am hoping for full-range sound at more modest listening levels.
After years of status quo, I ventured out recently to audition some new equipment. I listened to a low-powered (15 watt) integrated Leben tube amp paired to Dynaudio Focus 220 speakers (86 dB efficient). This was a great match although I am concerned that the sound will compress and the imaging will collapse at higher volumes or in a bigger space than the demo room.
Any suggestions are appreciated.
