Need some advise and guidance regarding the power amplifier requirements for home theatre use.
I have Anthem MRX710 powering my 7.1 setup in Home theatre, my components are as below.
Fronts: Ascension Summoner 863SQTL (150 WRMS, with 91 dB 1w/1m sensitivity)
Center: Ascension 253SQ (120/200 wrms/max (@ 60Hz plus), , with 91 dB 1w/1m sensitivity)
Surrounds: Polk T15 (20 watts → 100 watts, with 89 db 1w/1m sensitivity)
Surround back (Ceiling mounted): Micca M-8C (100 watts, with 90dB 1W/1M sensitivity)
Subwoofer: Martin Logan Dynamo 600x
Room size: 4m x 3.8m (Acoustically treated with Acoustic pin boards, Martini Absorb HD50 on all 4 walls with carpet on the floor, ceiling untreated.)
I like loud volumes when watching movies to get the same feel and punch one gets from commercial theatres. However, I have never gone past -10db volume level with Anthem, as I find other members of the household start complaining before I even get a chance to listen at reference level. This is for mainly HT use, I do occasionally listen to two channel music but it is not my main stereo listening room.
Some demo audio at close to reference level sounds amazing and feel like increasing the volume even more, however I find some movie scenes at the loud volume seems to be bit distorted or somewhat incoherent that I find the need to turn down the volume. I am not sure, if this is the limiting factors of Anthem's power amp stage or just room acoustics.
So far, Anthem has been the best AVR, I have ever had and Sound quality is really really great. Lately, I have been questioning, if I should add a power amplifier to the mix, and if I did, will there be much improvements to the sound quality vs the money spent? I am mainly thinking about adding 2 or 3 channel amp for front stage. I have seen countless posts on the net where people suggest adding power amp to AVR to boost the sound quality, given the Anthem MRX710 driving 7 channels, I don't think it outputs more than 80-90 watts per channel.
Will adding power amp to my setup give me better bang for buck?
As for the budget, It is very limited at this stage and I am thinking somewhere the range of $1000 for 3 channels. Unfortunately, most in this range are somewhat at the same power rating as the Anthem or less, that I think will not make much difference adding them.
What do you guys recommend, Is power amp really necessary and will it be a better investment? if so, what amps would you recommend to go with Anthem MRX710?
Anthem's MCA325 is an ideal choice to match with Anthem MRX but at $3600, it is way out of budget for me. Should I get some inexpensive amp now or perhaps I should save up and go for it when budget allows and be done with it or I am looking at this at wrong way and should perhaps target my speakers. I am quite happy with the front stage, my surrounds are cheap speakers, but they do their job.
What has been your experience when adding the power amp to relieve AVR of some of the channels?
I’m a bit confused about this now, because I’ve gotten different answers.
I am using the HDMI arc connection ( it’s the only HDMI out) (Denon avr-x1600h) connected to the HDMI arc on my tv ( Panasonic fz950 OLED (which is full bandwidth)
I have my 4K blu ray player and PS4 Pro connected to my avr HDMI ports.
When I’m playing a 4K movie with Atmos on my blu-ray player, am I getting it down-converted to something lower quality, or full lossless atmos?
I understand that playing something from my tv, eg the Netflix app, I wont be able to get Atmos.
When playing a movie with atmos connected to the HDMI ARC port of my tv, my AVR says Dolby Atmos – True HD.
Now when playing it on the HDMI non arc port, it says the say thing, Dolby Atmos -True HD.
Everything sounds the same.
Don't know how to explain this but here goes.
I have an Anthem 720 together with 7.1 speakers plus a Panasonic TV plus just purchased an Apple 4K TV device.
Netflix via the TV and the Anthem the sound is awesome, and when I press the mode button it says it is playing in surround sound.
Netflix via the Apple 4K TV it says Dolby Atmos but the sound is no where as good. It stutters and sounds awful and you have to turn the volume up so much to get anywhere close to the same via Netflix on my TV.
Any ideas what this could be?
