Yes the difference in bass got me interested in making Rew measurements as there was more difference than expected. Otherwise it was just a boring subwoofer leveling mission (which was not needed anyway, the gain in amps is nearly the same).
The really easy way for your own use?
You'll remember one of my suggestions was to check the polarity on the Fosi.
You’ll remember I said that was the first thing I checked. They were wired correctly. Regrettably, I did not attempt running it in the wrong manner just to see.You'll remember one of my suggestions was to check the polarity on the Fosi.
I can imagine this would be the case. I mean audibly most of my own (admittedly very minor forays) have suggested exactly this. Nope, none (justifiable audibility). But that is with listening. Can't hear any difference. Move on.
My suggestion specifically was
IE to check the amps, not necessarily your wiring. I'm not trying to criticise you here that you didn't, I'm just pointing out I was trying to work with you to find a cause - as well as informing you about how misleading bias can be.
This is extremely difficult to test, and I most definitely do not have the appropriate equipment necessary to test this. One needs a method to test the output from both amps simultaneously to ensure there is an actual delta-T between signals. As it was simply fixing an amp for my dad and then sending it off, the only qualifier was, “it makes sound.” I already put enough into gifting him the amps (with expensive, discrete **-**** rolled into them), and was not about to blow even more budget on expensive testing equipment—not to mention we were both anxious to get the amp back to the post office and in its way back to him ASAP, so taking time to acquire said testing equipment and perform the testing simply adds even more delay—my dad just wants to listen to his new amps already, man!
To tell the whole story here,there are cases that such a change can be audible.I can imagine this would be the case.

Because I come from the vinyl world where capacitance matters with cables etc. and because I think volume controls can influence the sound of an entire system, I wonder about impedance, and indeed anything else anyone might like to mention with this particular cocktail.
Digital outputs to amplifier inputs - all seems fine and dandy.
I have one example of FET vs Bipolar and it really niggles at me. So I see the monos as a way to test.
If I can muster up the energy in the next few months!
You see on ASR we need measurement afficionados to interact (like you have). And not preach.
Perhaps some members were doing this - I didn't read them all - and if they were, perhaps in that context my posts came across the same way. However my intent was to point out that your impression could be because of bias - in spite of how clear the difference you heard was, while ALSO suggesting other possible causes for you to investigate if you cared to.
Yes I had one of these big time mess ups where (they were correctly inserted) there was excessive bass. My subwoofers had to be cut right back so I just got rid of them immediately and went back.
Again - bias may have nothing to do with your conscious expectations or prejudices. They are built into the "wiring" of your brain, based on everything you have learned and experienced since the day you were born.
I have no idea what you are saying but hugs are appreciated. There are never too many hugs in the world.
Big hug @antcollinet - must be congenital hearing...
But this would not be conscious expectation or prejudice.
My tests with the monos might have conscious expectation or prejudice, because these are based on previous.
My previous had no previous.
Hugs all round. Tomorrow is a new day. Night night - it is the time for wise owls
Aha!I have no idea what you are saying but hugs are appreciated. There are never too many hugs in the world.
I spoke perfect sense (I think) but you are welcome to my world (not having an idea what someone is saying)
I think indeed it would be useful to confirm with the RCA ...that would be a strange one! I'm also using balanced.I just played the following stereo system test tracks through Tidal:
Bunker Analog - Stereo Test: Speaker Setup, Calibration Tones, Soundcheck
Listen to Stereo Test: Speaker Setup, Calibration Tones, Soundcheck on TIDALtidal.com
The second track is a phase test, and my system tested fine for in-phase and out-of-phase. I also confirmed left and right connections were correct. I am using all balanced connections too. I could try RCA connections to determine if something is off with single ended connections.
My wife was listening to the system and she was very impressed with the V3 Monos. She said the sound was very three dimensional and the KEF LS50s disappeared. Hope others can sort out the phase issue they are experiencing.
Is your system out-of-phase? Using the cited test tracks, my system is in phase without a doubt.
I'm not signed up for Tidal but I do have a test 'CD' stored on my hard drive when I get back to my system. I am sure that it will have a phase test.
