First thing about the Halo was that it took about 3 to 4 days of playing it constantly before the sound settled down to what it is today. Like I mentioned, the Halo provides a lot more detail than the Rotels that I was using before and the Rotels were a big improvement over the Carver I had before that. I had the Halo on my older DT's (BP2004) and they produced more bass over the Rotels in fact I had a room peak around 80 Hz. This went away when I got the BP7001sc and put these up front and put the BP2004 as the surrounds.
The subtleties are pretty good with these speakers and amp. When playing something like a group 'Over the Rhine', the subtleties in the recording can be mesmerizing especially female voices. Playing some other stuff like Nine Inch Nails which can go from very loud to very soft to very loud again, it provides a pretty good kick and keeps up with no problems.
For fast response of the system, I use the opening of Sarah McLachlan's 'Building a Mystery". Around 17 seconds or so, it sounds like someone bumped a mic stand. I feel that if the system is slow responding, you won't hear it. But this comes through real clear on this amp and didn't necessarily on the Rotel. With the Halo, I hear a lot of details but sometimes I also hear the limits in the recording which can be disappointing. The topic of bad recordings are left for another day.
The A52 is rated for 120 watts but has a huge current reserve. I can drive the system to 105-110 db and no problems except that it is too loud and rattles the furniture upstairs. I could go a lot louder but don't want to break anything. The A51 seems to handle everything well from very acoustic material to very hard rock. I don't listen to much classical or jazz so I can't comment on this type of music.
If you go this way, you won't be dissappointed. I bought the amp at one store and the speakers at the other and both salespeople said the amp would be a great fit and don't worry about anything. The A51 of course has more power but I don't think that you would ever need it. From what I read, the electronics are the same between the 2 except for the final power section.
