Have you contacted CA about this? I'm curious of what they have to say. I may send an inquiry.

I did, but you know their CS is the worst on the planet. May be multiple users raising the same concern might jolt their self respect. All this time I've been taming my sub in Stereo+Sub mode not knowing that it was all wrong measurements. I only got to know when I applied 3 BFD filters to bring down 3 peaks in my FR with 80Hz crossover, and the 2 filters after 45Hz had no effect. I thought my BFD developed some fault. To further check I applied 48dB cut (maximum) at 53Hz and there was hardly any difference. The reason is that 53Hz frequency was not being served by the sub despite an 80Hz crossover, it was in the speakers.

I sent a "query" to CA about the "bass management issue". Asking if the update is available yet. biggrin.gif

Others should do the same.

And if you are from the Western World you should also apologize for having the NERVE to contact people at CA. Because you know they don't want to interact with filthy yanks, like us. rolleyes.gif

Makes me almost want to stop watching British TV shows mad.gif ............well....not really. But I've thought about it. tongue.gif

That is world's most bizarre customer services;

Dear Sir, I am sorry for the delay.
I have raised an internal engineering issue with your comments and those from another customer. This will take some time to study, identify the fault and correct. As such, I am afraid that there is no instant resolution to these issues.
I am sorry I cannot be more help in this instance.

These idiots should be banned at government level for pumping out junk into market without self and regression testing or they need to be educated on what exactly bass management is.

If it wasn't for the SQ in movies, I'd have thrown this AVR away. mad.gif

Yes. But bass management is best left to the AVR and crossover on the sub is bypassed in order to not have cascading effect.

Has anyone tested bi-amping after FW upgrade to 1.51 on 751R? The bi-amp light on the front display doesn't come on even when it is activated. I think the CA idiots missed the indication light also in the FW upgrade.

Gotta reply about bass management.

"This is being worked on at the moment and we hope to release something useful shortly."

Maybe someone should remind them about the Bi-Amp light not turning on. I'm not using it that way, but one of you fellows doing it should send them a query about it.

I wonder if anyone tested these things.
OK they did.
But did anyone THOROUGHLY test them.
You know......... make SURE everything worked right.

Understandable. BUT the unit won't get any worse and every update will fix a few things.

CA AVR's. I've never ENJOYED and DESPISED a product so much, and AT THE SAME TIME.

Yea, I know. The last thing I need to do is trade it in for some x brand whatever and spend the next five years beating my head against the wall. This really is an impressive receiver. Thanks for pullin me back!

I did a "hardware reset" after the FW upgrade on my 751 today. I reran the Audyssey basic only, I figured I would do the 2eq later since I dont use them. Anyway, something is different. My music sounds alot better than before. I turned on the Dynamic EQ and turned the treble and bass to 0, and I couldnt believe how loud and clear my music sounded. I just thought it sounded good before. Some of my favorite is Cheap Trick's Heaven Tonite on my ES minidisc player through analog. These are recordings from the 70s and hard to get right, but the 751 has nailed it better than I ever heard. Does anyone know if the Audtssey setup affects the Dynamic EQ settings? I'm thinking that I may not have done it right the first time or my receiver is just now coming to life. I was blaming the lack of midrange on my new polk speakers, but now I really cant complain about any of it. I've been having a real "love-hate" relationship with this 751, but I cant imagine getting anything else.

Hmm. Interesting.

I have to ask a couple things. Weren't the bass and treble ALREADY at 0, after the reset?

AND what did you have them at before?

AND finally, how long have you had the unit? Is it getting close to a month?

WTH. cool.gif

So I just did a reset. Ran Audyssey Setup (NOT EQ). And well.......

I'm not going to lie. It DOES sound better. tongue.gif

But it might be all in my head. wink.gif Might be leaving all the audio settings alone.

Something to try once in a while just to see what I think.

751R opens up in the mid-range and upper frequencies after about a month or so of use. The difference is very much noticeable. Every room is different and your room may be calibration friendly for audyssey. After reading your post, I also ran Audyssey and to be very honest I didn't like it one bit. It actually sucked the mid-bass out of it (80-200hz). Even after disabling it, I still was unable to get my old settings back. So I gave it a hard reset and ran it the way it was manually calibrated with only DynamicEQ.



Back to life.

Yes, the Tone settings were at "0" after the reset, but I adjusted them up without trying it, I was running the treble at 8 and the bass at 8. Now, I just put them back on 0 and it sounded way better. The unit is 1 month old now.

I ran the Audyssey cal. but turned it off. I agree with bh123, the Audyssey sounds bad. Dynamic EQ is where it at. I was wondering if the Audyssey calibration affects the Dynamic EQ's set points?

I think it does. Coz after disabling audyssey, I could hear different sound (thin mid-range) even with DynamicEQ engaged and bringing back my old settings (distances/levels) compared to when I didn't run audyssey at all with the same settings and DynamicEQ engaged.
I had to reset receiver and redo the manual set up, which brought back the missing mid-range.

CA vs NAD was a toss-up for me. I was not willing to wait for the new Anthems. I wanted some eq capabilities but was so dissapointed in the first two systems I tried, I went back to just my old 31 band eq on the sub and went T757. The main reason over the CA was I was able to get better re-assurences the NAD HDMI switching was reliable. If there was a CA dealer within 100 miles of where I live, I would still love to have one demo'd. Maybe they could get me to swap out my old Rotel 1055.

THe NAD works fine. Nothing special. Nothing wrong. It works. I can see why that would not give rave reviews, but after having HDMI issues with O, E and Audessey issues with M, just working is a big deal! I may still swap in my old Parasound for the front amp. My other upgrade was an oppo. I am extatic about it because... it works. I don't need to go get a cup of coffee while it decides to boot and maybe, eventually, if it feels like it, after enough Javaboot time, open the tray. Nope. You can turn it on and by the time you open a DVD case, open the tray. Sounds trivial,but it is the firast I have ever found that does. Nice work on old DVD's too.

If an AVR has ANY eq capability after tone controls, I would think managing 53 Hz would be the number one priority. Sad to hear CA can't. Ausessey did not. The Emo actually tried, but had so many other issues I sent it back.
Even a fixed narrow Q notch for both mains and subs would be a 90% fix. Remenber when we used to have "rumble" filters?

With CA, you can only associate two things. You love it 100% and, at the same time, you hate it 100%. The former is jaw dropping performance both in music and movies and the later is CA customer service, which makes you wana think you are one of the victims of Tobin Bell in SAW......very painful.

In much of the world, we have 8 foot ceilings in most homes, so 53, 54 Hz is a major problem. Not so everywhere. Just as a rumble filter in the US was 60 Hz, it was 50 just about every where else. I had a room once withthe smoothest bass I have ever heard. Not only because it was a large room with vaulted ceilings, but as it was a mobile home, the walls were just about transparent to bass so they caused no major modes!

I have a 11' X 16' finished room in the basement that I'm slowly converting to a make-shift movie and music room. It has an 8' drop tile ceiling. I wonder how the bass will sound. I'm afraid the ceiling is going to rattle real bad.

I have two Infinity 10" subs and a old polk with two 10s in it. One of the Infinitys would probably do. I need to do a sound check first before I move all my equipment in there.

Yowser! +8! eek.gif That's a LOT. Looks like a battle between treble and bass to unbearableness.

I used to +2 treble until the upper end opened up about a month into use. Now the AVR doesn't need it.


Ah! One month old. There's some other stuff going on in this case, but there is definitely a "one month old" change that goes on with these 2 AVR's.

Ah! One month old. There's some other stuff going on in this case, but there is definitely a "one month old" change that goes on with these 2 AVR's.


I know, I just couldnt get the sound just right. I was constantly tweeking everything.



I think the owners manual mentions a break in period. I can defiantly tell a big difference between now and when I first plugged it in. I hope it keeps getting better. My speakers are Polk RTi A7s, and Polk claims that it takes 80 - 100 hours to break them in. Thats a long time I think.
