if one is willing to deal without the bottom octave and a half of bass, the pinnacle pn2 model [an oldie but is available here and there for rummage sale prices] is hard to beat in terms of its relatively uniform frequency balance and holographic imaging. it is also fairly sensitive in terms of getting to room filling volume on relatively little amp power [less than 10 watts per channel].
Bookshelf speakers- Buying a Bargain
Buying a bookshelf speaker has more variance in performance than any other audio item IMO. Over the last 30 years I bought sbout 20 bookshelf speskers. Most do not sound good at all. Mission, Klipsch, Pioneer, Wharfedalw were all poor performers. Only two bookshelf speakers I bought sounded good with great articulation and low distorting being Revel M22 and Audio Monitor Silver 3i. Revel M22 are too rare and too expensive. However the Audio Monitor Silver 3i and I suspect any Silver series are great speakers and the Silver 3i are about $300 on eBay. Per what I read the Bronze series are rather ordinary- avoid.
I always used rebuilt and upgraded Tube amps with best sounding tubes thus did not mask speaker performance.
