No word yet @amirm? Curiosity getting to me...FYI Anthem has kindly contacted me. I am following up. Nothing else to report.

That's if you want to make it into a study and prove/disprove it on a large sample of participants.The cost to setup blind testing, ensure the listeners aren't just trained, but have excellent 20-20kHz hearing, creating a properly treated room, using only speakers that everyone reading will agree are the best of the best, etc., etc., would cost in the $ millions (and you'd still find someone complaining that something isn't quite right, or the listeners are somehow corrupt). And this is why ASR uses the 115 dB threshold, because it is beyond any human hearing and it costs way less than humans listening in a controlled environment.
Aye, the room is the "elephant in the room" in terms of audio quality and 95% of the audiophiles completely neglect it.I guess in a typical untreated listening room, and with passive speakers, the room itself makes much more audible difference than an amp ever could.
You can. You just have to be brutally honest with yourself. If you have to go back and forth multiple times and strain to hear a difference, you can already be sure that there is no difference worth mentioning in practical scenarios.As a single user, I only care about what I can hear or not hear with my speakers and space. If I could test it on own and hear no difference, that would be enough for me.
This. And, in many cases no one can even tell which is the "right" sound. Even if you were present at time of recording, in the jazz club , or philharmonic etc., at every seating place you have different sound, and your place was guaranteed not at the microphone(s). Then, when comparing stuff, the louder sound will be perceived as better (popular error with comparing speakers, the more efficient win). Nothing is ever perfect.Our brain is so easily tricked, it even tricks itself.
I’m not advocating any particular method for establishing whether amp A sounds better than amp B. I’m just asking whether two amps with inaudible levels of distortion at a given output sound the same (all things being equal)? Then I’m intrigued as to why people buy expensive kit, if there is no audible benefit in doing so.
I know I can cause I'm such a skeptic May not be true to others. I got a DAC to see if I can tell the difference bewteen using my CD player connected directly to the amp or with it going through a DAC first. I can safely say that at least with the level of other equipment I have and my hearing, I hear 0 difference.You can. You just have to be brutally honest with yourself. If you have to go back and forth multiple times and strain to hear a difference, you can already be sure that there is no difference worth mentioning in practical scenarios.
E.g.: with the DSP off, I can hear no difference between my shiny new ADI-2 DAC and my old Titanium HD soundcard when using the DT-880 (that isn't modified much by the difference in output impedance).
Problem is: if you want to upgrade and want your new hardware to sound better, it most likely will. Our brain is so easily tricked, it even tricks itself.
https://www.audiophonics.fr/en/sour...tch-for-speakers-amplifiers-black-p-5400.htmlThe problem for me is how to set 2 AVR/Amps with the same speakers and be able to switch between them on the fly. I asked about it earlier on and was told a switch box, but I'm having trouble envisioning how that would move the speakers from one amp to another.
Awesome, thanks. Can a switch box cause any sort of deterioration? I mean, do I need to make sure I get a specific brand?

Anyway, I'm not planning on doing any upgrades, I'm just interested to know how to do it theoretically.
Forget manual switches, you'll need a switch box with relays and control it from you listening position. You also need a proper way to measure and adjust signal levels from your amps.Awesome, thanks.

This is the only way I would trust myself with comparing, anything that involves even a few seconds of "downtime" when moving from one to the other would not work for me.

There are people who swear to be getting a huge improvement when they switched to this or that ampI’m not advocating any particular method for establishing whether amp A sounds better than amp B.

Sounds like the perfect home comparison. I will bookmark this switch too. Thanks!I plan on comparing the AT525NC to the Benchmark AHB2 sometime in the next month. I was going to do this earlier but life intervened.
Here is the plan:
Here is the switch:
- Use Roon to a RPI3 DietPi Roon Bridge as the source.
- Use the SHD 4 DACs to copy out 1 to 3 and 2 to 4 for simultaneous stereo output.
- Use a multi-meter and sine wave signals to gain match the outputs for each amp (this can be achieved with 0.5 dB, not ideal but not bad)
- Send each stereo output each set of channels to an A/B amplifier switch.
- Switch between inputs in a Single Blind Test

This may not satisfy others, but it is interesting what can be done at home.

Yep. The switch part is what I was missing. Now I got to two bookmarked, so I'm theoretically prepared for when I'll need to do suchForget manual switches, you'll need a switch box with relays and control it from you listening position.

SPL meter isn't precise enough. You need to measure output voltages (with speaker load).Yep. The switch part is what I was missing. Now I got to two bookmarked, so I'm theoretically prepared for when I'll need to do such
I have an SPL meter so I can get pretty close with level matching I believe.
Maybe the Anthem rep will say ok ok I hear you loud and clear. We will give you an AVM70 as you have made a lot of noise with the AVM60 and back pedal from their previous comment that a AVM70 won’t be available for ASR as they have many other reviewer who have priority. But if anyone here is willing to send Amir a sample, that’s ok too.No word yet @amirm? Curiosity getting to me...
Where did they say that?We will give you an AVM70 as you have made a lot of noise with the AVM60 and back pedal from their previous comment that a AVM70 won’t be available for ASR as they have many other reviewer who have priority.
I just checked and for both analog and HDMI input the mode button says, "None." For some reason, setup button no longer brings up the menus. I am going to pack the thing now and send it to its owner.....
