I just picked up the AD 250 and am looking for a decent pair of bookshelf speakers ($150 - $300 range) to pair with it. Currently using a pair of Yamaha AP4400S's that someone left on the sidewalk a few weeks ago.
The AD 250 is supposed to put out 50 watts at 4 ohms and 30 watts at 8 ohms. I was cautioned by a (Crutchfield) sales person that my amp is bit underpowered for some of the speakers I am considering (ELAC 5s or 6s, for example).
The AD 250 seems to meet my needs -- small footprint and very simple -- but I would consider another amp if I really need more power. Strong preference to avoid a full-sized amp, however. With the Yamaha's I am using right now I've noticed the volume knob needs to be somewhere between 1/3 to 1/2 of maximum to get the volume level I typically like to listen at. Most of the bookshelf speakers I am looking at have larger woofers, so I see a potential problem here. (Aside from the ELACs, speakers I've seen with good reviews from websites like What Hi Fi include Dali Spektor 2, Q Acoustics 3020i, Wharfedale 220s. Also looking at Polk S15s, which may be a better match for a low-power amp).
The speakers will be set up in a bedroom (about 150 sq. ft.), but I am trying to push sound into another smallish room. I don't envision playing anything terribly loud. I am also using a chromecast audio device, which connect my bedroom speakers with a similar setup I have in my living room. W
Does anyone have any recommendations for (passive) bookshelf speakers -- either specific speakers to look at or specific properties to look for (e.g., sensitivity above a certain level, speaker size less than x inches, etc.). Or is there a different (DAC/)amp you recommend I look at?
