Ok as long as you tell about CD player... But look it as a drive (I2S or Coax to your lovely DAC) and you get a winner...

It seems so when I see smsl claims for 132dB SNR for XLR which are 5 Volts. Am I correct to believe si?

Hello Excellent question ! Did you get an answer?

This is why 32 or 36 are less performant than 42 or 48. After curent is important and on 4 or 8 Ohms load, 8,5A will deliver more then 5A even if voltage is only 42V. Very good value for money for this Audiophonics 42V 8,5A PS I mentionned earlier. Worth thé test

Just a question of more power available for delivering this highly demanding spectrum area. You call it frequency response. I didn't.

At this stage I suggest best fit with Fosi V3 and Aiyima A07MAX (stereo config and mono config) is Audiophonics one : 42V 8.5A https://www.audiophonics.fr/fr/adaptateurs-secteur/adaptateur-secteur-alimentation-100-240vac-vers-42v-dc-85a-p-17308.html?search_query=42V%208.5&fast_search=fs Better...

as long as you apply that same 2.83 V throughout the frequency range 20-20,000 Hz, you will get the 86 dB @ 1 meter, This clarifies a lot Many thanks

Thanks for all Guy's : I'll have a lot to digest : I was focussed on Power and have to review all my mental processes Thanks for all your clarifications. As said : I was here to question and understand . I have now my part of job

Thkx Antcollinet I was confused by the RMS volts !

Thanks Peng, Gasoline Antcollinet and Turtlepaul These are exactly the kind of insights I expected ! The speaker is a four loudspeaker having a complex load "nominal 8 ohms/ minimal 4 ohms) Final question : 42V-8.5A and Fosi 48v 5A are in similar price tag (the 48v 7A is 3 times the price)...

I don't take into account the capability of PS to exceed rated power Audiophonics 42V 8.5A If 4 ohms 42/4 = 10.5A per channel requested if 8 ohms 5.25A per channel requested In both cases max current is 8.5/2 = 4.25A is the limitation => 42*4.25W per channel =178W Fosi 48 5A 4...

Hello Gasolin75 I thought that if the Power supply is 48V on let's say an load of 6 ohms, U/R = 48V /6 Ohms 8 Amps is requested per Loudspeaker But Fosi is limited to 5A in total so 2.5A per channel So per channel P=U*I =48*2.5= 120W per channel Same with 42V , 7A requested ; but 8.5A in...

What would be the best match for getting best power from Fosi 48V 5A or Audiophonics 42V 8.5A power supplies? Is this correct to expect max 48v*2.5A =120W per channel if Fosi and 42*4.25A = 178.5W with Audiophonics whatever the load between 4 and 8 Ohms?

Thanks, Interesting. Since some months/years , Amirm doesn't find any bad measurement .. Maybe these tests are finally useless. Good to know..
