Found it better than my Denon AvR 2805 100 channel amp. Put my ear on the speaker and it was clearer on A07 max. I heard distortion using my Denon. Believe it or not Im using that amp full volume on large bi amp speakers that push up to 300w.
@@ryanchappell5962 okay, thanks. 1. How much time did you spend with the 5532 and did you like the 5532? 2. Are you actually getting better fidelity by changing the chip? Or do these different op amps affect the frequency response mostly?
@ I listened to the 5532 for over 100 hours. I noticed a change going from the 5532 to the LME49720. The sound seems a bit more real and perhaps less forgiving which is probably due to speed of the LME. The differences between the oracle and LME are a bit more difficult to determine. It’s different but I’m not sure if it’s better at all. My guess is that the slower speed of the 5532 gives the amp a smoother warmer signature and faster chips like the LME, Sparkos, Oracle are going to be more direct sounding.
Easier teardown ... take the volume knob off, remove the nut underneath, take the two outermost screws out of the back, slide the whole thing out the back. Op-Amp wise ... don't waste money on exotica. Plain old JRC4558s at about 50 cents a piece will give you a noticeable improvement. FWIW the actual improvement is not putting in fancy op-amps, it is in getting the crappy 5532s out of there. For power ... with a 48 volt power supply you will get an honest to goodness 100w/ch with very low distortion on an 8 ohm speaker, up to 200 watts on 4 ohms. Speaker wise... these amplifiers are wasted on desktop speakers. Try letting them loose on something like a pair of LaScalas, Heresys, L-100s or Lintons... now that's a real treat.
@@scottbennett3119 No ... I'm saying it's better than the 5532 that comes in the amplifier. You can spend absolutely ludicrous amounts of money on these exotic chips... but the first step is to see if you need to. In many cases all the improvement you're going to get comes, as I said, from getting the 5532 parts out of there.

Hello, very intriguing video! Did you get a chance to try the Oracle op amp? I just bought the A07 Maxx and am interested in your outcome.
@@scottbennett3119 I am trying out an Oracle II 02 now and I’m not sure if I prefer it to the LME49720. I will need to swap back and see.

@ryanchappell5962 Thanks for sharing that. I am weighing the options...

Are you saying that the jrc4558 is the better choice for higher fidelity sound? I am looking to achieve better sound quality.
I just ordered the 4558D - dual op amps
