My concern about those is AVForum reviewed them as being on the bright side, and the previous edition of them was reviewed by Sound & Vision and mentioned them leaning on the bright side. Heavy metal recordings are often very forward in my experience, and I would want a neutrally voiced speaker for that.
How loud do you really listen? 105dB peaks at reference on the LCRs in movies to me is very loud, I tend to listen at -10MV or lower even for spirited listening sessions. My LFE channel is run a little hot, and basically runs at reference, but my mains are considerably lower. Music, especially heavy metal, has WWWAAAYYY more sound energy than a movie. A movie you get a quick pop or boom at 110dB, heavy metal it will be very sustained. If you listen at 110dB you are going to get hearing loss very quickly.
That said, I'm not your mum, with the Sierra Towers's and Monitor Audio's you'll for sure need an external amp to reach those peaks. So factor that into budget. If you want to reach those levels with a receiver, you might want to consider something horn loaded like Power Sound Audio. They have good service and are very sensitive. Their towers will hit 110dB will just 10-15watts depending on placement at 8ft away.
I too am concerned about the Silver 500 being slightly on the bright side. I have tried the newer Bronze 5's, and I found them to be a bit hot when it came to snare hits & overly sensitive to vocal sibilance. They did have the much-improved bite and clarity to the electric guitar range I was looking for but at a cost. I am trying to figure out if the Silver 500 and Bronze 5's share the same tweeter because I suspect they do. If that is the case, I don't know enough about speaker design to know if a different crossover or design could tame that in the Silver 500.
I certainly don't listen at 110db. I have a sound meter, and I mostly listen in the 88-92 range. However, I like having plenty of power on tap, should I choose to play a couple of songs at 100-102db. I like to have some horsepower on tap, and for my gear to show zero stress should I choose to exercise it.
I'm currently using an Onkyo NR901, which is an older flagship AVR (pre HDMI) with a large power supply and amp section, fully 4ohm capable. I use it for the bass management mostly. It seems to sound good but I will probably grab an Outlaw RR2160 at some point "just because". My budget doesn't have too many limitations other than whether I feel I'm getting a good value. I'm won't be keen on getting into the territory of diminishing returns.
The PSB speakers do look interesting, I haven't considered them before. I don't have much experience with horns but they scare me because I don't want anything too in my face. I have some Cerwin Vega RE-38's, which are 15" woofers & 102db sensitivity. Overall they sound decent but don't come close to even the older Monitor Audio Bronze B4. In comparison, the CV's sound more two dimensional and boxy, plus lacking in instrument separation. I suppose I am looking for a neutral sound signature (perhaps with a touch of warmth) with excellent mids, a three dimensional sound, and a top-end that is detailed enough before getting anywhere near "bright" territory. I just described the Sierra Tower, didn't I?
