I was a litte nervous when hooking up the M60 to Crown...But after hooking up, I could notice the difference as compared to the Onkyo.
Below is my summary (some of you may not agree if you're a big fan of Axiom)
1) crown/BMB vs OnkyoNR801/M60: BMB sounds better
2) OnkyoNR801/BMB vs OnkyoNR801/M60: It's hard to tell which one is better
3) crown/M60 vs OnkyoNR801/M60: Sounds more accurate, cleaner, tighter, stronger on Crown. I guess this is expected because the Crown is much stronger than the Onkyo
4) crown/M60 vs OnkyoNR801/BMB: M60 is much better. I guess because BMB designed for Bar/Karaoke. Onkyo is not strong enough to drive it.
5) crown/BMB vs crown/M60: On low to mid volume. I like M60 better. On high volume or Karaoke (mid-high volume), I prefer BMB
My conclusion:
- Crown DOES make a big difference. Only problem is that the constant running fan is a little annoying sometimes.
- If everyone rates the M60 high, then BMB CS500 is too cheap for its price ($295). 3 times cheaper than M60, but sound very nice. Don't get me wrong here, I also like M60 much.
Anyhow, thank you all for your suggestions.
Cheers!
