Which amplifier?

355 Views 8 Replies 4 Participants Last post by  jdsmoothie
I'm going to be running a Clearwave 4T & CC front stage. I'm trying to decide which amplier to use to get the best bang for the buck. My current receiver is a Yamaha rx-v663. I'm torn where to best allocate my money.

I won't do a ton of stereo listening but will do some. I would probably say 80% Movies & 20% stereo listening. For those unfamiliar, my fronts require 65-360W and have an 88dB sensitivity.

Here are some of the options I've been looking into.

1) Upgrading my receiver to a Denon x7200

2) Emotiva XPA-3

3) 3 x Emotiva XPA-1L

4) Emotiva XPR-5

I'm not sure about getting the new Denon as I'm still waiting to see what becomes of the 3D sound war between Dolby Atmos, Aero 3D, & the future DTS-UHD. I figure if I wait another year I'll at least get all 3 decoders.

I'm not sure going all the way to the XPR-5 would be worth the almost 3x price tag over the XPA-3. Same thing with going the route of the 3 1L's. It's only an additional 50W per channel for almost double the cost.


Any other suggestions are welcome.

You could check an SPL calculator to estimate how much power you might need: myhometheater.homestead.com/splcalculator.html

I'd hold off purchasing any amp if purchasing the X7200W as this AVR should provide more than enough power for your speakers. Atmos comes pre-loaded, while the Auro 3D upgrade will cost $199. No information has been released yet on the availability of the DTS:X upgrade.
Your fronts don't "require" 65-365 watts. They put out 88dB with merely one watt if that is a proper sensitivity spec. No sub?
^^^ They put out 88 dB at 1 m with 1 W input at the frequency or range of frequencies used for the sensitivity measurement. Ten feet away, a single speaker only puts out 78 dB'ish. Put another way, you actually need 10 W to hit 88 dB from one speaker if you are sitting ten feet away. And 100 W will put out >100 dB from a pair of those speakers ten feet away, loud enough for me but I need my ears. Probably doesn't really need an external amplifier.

I agree if the OP does not have a sub then that is by far the biggest bang for buck proposition.

Just a point that the speaker will put out a significant amount of sound with 1w, i.e. it doesn't require a minimum of 65w....but since we have little idea of his room or use....

I think the sub is what he's missing, will lighten the load on the avr/amp used as well as supplement the low end where those speakers don't go.
Thanks for all the replies. The SPL calculator was a huge help with making my decision. I have a sub. It's a Dayton Audio Ultimax 18 I'm actually trying to find an external subwoofer amp as well it's a 1000W RMS dual 2 ohm VC. My room size is 13 ft W x 21 ft L. It's a theater set-up with 2 rows of seating stadium style. The first listening position is maybe about 8.5 ft from the fronts and the second seats are about 13.5 ft.

So do you think I should wait or go ahead and get the Denon x7200?

Popular sub amps are the Behringer iNukes 3000DSP & 6000DSP. I use a Crown XLS1500 for my sealed SI18HTs mostly because I already had the amps, but haven't decided yet if I'll go with one sub on each their own 1500 in bridged mode (1440w at 4 ohm) or as I'm currently trying one on each channel of one amp (525w/ch).

If you like the features of the Denon, particularly Atmos etc, I think that's a good choice. I recently got the 4520 as I'm not going the Atmos route, XT32 was my main reason.

The new production line units with the HDCP 2.2 board will likely start shipping in June, so if you don't want to wait, and don't mind sending the new purchase in at a later date for the HDCP 2.2 board upgrade, might as well, not to mention a purchase in March also comes with a free Denon HEOS Link ($MSRP $349). :) If you want more specific information or pricing on this product, please contact us as we've got 2 in stock at this time.
