Just updating with some photos.
Word of advice for folks looking into this amp or the 7x+ versions of this amp. I didnt put much stock into the 70+lb spec sheet on this 5X amp. I’m young and fit I thought. this amps weight is no joke and actually adds some difficulty to things. Simple putting it in the rack/shelf you have to be careful and thoughtful. Next sliding the rack back to the wall was quite the task TBH. however it is in now and i couldn't be happier!
Today i re-ran Audyssey. Using the Audyssey app. It gave me better results(bass) then just running on the 4300H for some reason. I then limited the correction to 1K hz and under for the speakers. Used the curve editor to help a bass dip at 70hz and now its time to listen.
First of all, congrats! The Anthem amp is nice and I have one. The Monolith has a larger power supply and the 70+ is expected, due to the large transformers.
Just one point on Audyssey using the editor to edit, if you simply use the App to shape the bass curve, it will be extremely unlikely to help your 70 Hz dip especially if it is one of those narrow ones. To actually help (but not eliminate) such a sharp dip, you have to use the App with a 3rd party UI such as Ratbuddssey and that's one reason why I created a thread for it.
It would be difficult and potentially lengthy process (2hours or more), as you basically have to lower all the peaks across the board by a few dB to level the 20-20,000 Hz and then increase the level across the board back up to compensate for the otherwise much low level. It is more complicated than that but that's the basic idea.
Thos narrow dips, according to experts including the respected Dr. Toole, are practically nothing to worry about. Again, you can't do much about it and it isn't actually an issue audibly speaking.
Below are example of such dip(s), and it is Dirac Live, so Audyssey is not the only one that couldn't fix such issues.
One that can be much improved, but potentially very time consuming depending on how ocd one is:
It can be much improved because the dips at 75 and 96 Hz are not very sharp dips. I tried lessening those dips by shaping the curve, that was easy to do with Dirac Live, but it still result in the two sharp dips. To improve it much further I would have to play around for hours, potentially. Even then, I am sure the dip at 96 Hz would remain while the one at around 75 Hz would become much better looking.
One can shows the sharp dips at above 120 Hz could be improved to some extent only while those at the lower frequency were virtually eliminated using the Editor App with Ratbuddyssey.
