I’m using a RX A1050 to run a 5.1 setup. Will it make my front (BMR) speakers sound better if I add a 2 channel amp? I only listen to music and medium volume. Budget $500.

At medium volume levels I would think that the 1050 would be able to power the BMR's just fine. Of course, that really all depends on what YOUR "medium" level is and how loud you really want to be. Not to mention, how far is the MLP from the front-stage?

Adding an outboard amp can improve things, but I honestly think your are fine w/the 1050. It is known to have a beefy amp section. How do you listen to your music? All 5-CH's?


Cheers,

Phil

Sometimes I use 4.1. Any recommendations?
If you are using mainly 4.1, then I would look at the Outlaw Model 5000 amp. It is, of course, a 5 CH amp, but not much out there that is going to best it for the price. It is going for $599 as we speak. Here is a link:

The B-stock Model 5000's are sold out at the moment. The Model 5000 is conservatively rated at 120 X 5 RMS@ 8 ohms and weighs in at a hefty 50 lbs. So, it is a monster to say the least. Highly recommend if you plan to add an outboard amp! :):):)


Cheers,

Phil

From the specs of your receiver: (nice specs btw)
Dynamic Power per Channel (8/6/4/2 ohms) 135 / 165 / 210 / 280 W
Rated Output Power (20Hz-20kHz, 2ch driven) 110 W (8 ohms, 0.06% THD)

I think you already have more power than your need. I have 75 watts per channel and it's plenty. I'm listening to my BMRs loudly at -20db. I don't think you really need to upgrade, but say you got a really nice power amp all it would do is give you more headroom and maybe cut down a tad on the THD. - Would you hear a difference? IDK.

The only concern I would have is when you are driving 4 or 5 speakers with the 1050, there is some possibility of the combined load of those 4 or 5 speakers stressing the power supply.
This would depend on:
1) what mode you are using to determine the signal of the additional (from stereo) channels - for example, if you are running multi-channel stereo, there is a good chance that all channels would see demand peaks at the same time; where as most movies will not (an explosion to the front-left will arrive at each of the speakers with different timing). So worst case is your maximum peaks are occurring on all speakers at exactly the same time.
2) what is the impedance and sensitivity of the other speakers. If you are running Gene's Status Acoustics 8T's as your surrounds (which are power hungry and drop below 3 ohms),you are overloading your amp before even adding in the mains!

I suspect you are fine as you are, but we can't rule out the possibility that your system might tax the AVR without knowing this.
One test you could perform is to listen as loud as you ever would to the 4/5 speakers, then switch to stereo and listen to see if it sound cleaner of not. I feel very comfortable that your AVR would handle 2 BMR's by themselves without issue, so that can be a reference.

I can't speak for the Yamaha, but I used to own a 50WPC 5.1 HK AVR that had no problem driving 5 speakers (min impedance 2.7 - 3 ohms) - Def Tech BP7000SC, BP7001SC, CLR3000.
