It was a pair of Twenty.24s that I got after auditioning the PB1i. In all fairness, the comparision should have been made with OB1i or perhaps even a lower model but that I don't believe was the issue. What I did not like was the overall presentation; Basically, to me the Twenty.24s highlight the top end tad too much, I mean it is great when you listen to a well recorded 24/96 percussion track with the extended dynamics of hi-resolution recordings, the symbols come out with such realism and strength that you can imagine the band to be right there in the room but I also noticed it masked out some of the midrange detail. The 24s midrange itself seemed slightly recessed compared to the rest of the range. Again I have to say the 24s midrange was astonishingly airy and the wide dispersion characteristics and imaging capability meant the Twenty.24s simply dissapeared, and it seemed as if I was right in front of a tall, wide, wall of sound so it was good from a soundstage perspective. But in the midst of all that, I felt I was missing finer details of the mid, vocal range. Textures could be heard but I found myself having to concentrate harder to pick up details - difference in presentation most likely to blame. With the low-end, I felt the 24s were slightly too tight (if there is such a thing) for my taste, one thing that struck me with the PB1i was its slightly relaxed bottom end - didn't appear to have the same solidity as the 24s but when a different track was played, I could hear tight, impactfull low notes with a great amount of detail & character coming out in that region - it seemed like the PB1i let out low-notes as-is in the recording without adding its own "tightness". Dont get me wrong, the twenty.24 low-end was taut, articulate and extended but for me, it lacked the level of energy & finer detail I was looking for. At the end of the day, I was comparing the Twenty.24s with a speaker twice as expensive so that is my fault. Then there is that difference in electronics and of course floorstanders tend to be more sensitive to room characteristics but at the end of the day, the one thing that mattered was whether I could see myself enjoying the speakers long-term and I felt that would not be the case.
