[drMordor]

For San4 and all
bypassing OpAMp pins

 

[nerone]

Nice progress Vitaly!
I thought high quality capacitors were going to used in this version of your amplifier? I see Samwha caps in the PSU, not a brand I would consider “high quality” and sourced from reputable suppliers like Mouser, DIGIKEY, etc...

 

[drMordor]

Samwha use in reputable amps as nCore, this is normal caps

Caps

drMordor, have you only tried with OP AMP1656?
Could replacing the 1656 with another op amp change the sound?

Thanks for the added information drMordor

Guys, I tried to make a good amplifier with a low cost, I can use any capacitor you want, but it will increase the cost.

My "AllInOne" amp came with 5532s soldered in place. It is a wonderfully neutral sounding amp! I don’t want to swap them out although I don’t doubt that putting 1656s in place would give it a richer sound.

Cheers, Pete

OPA1656 is my idol now))))
Compared with AD711, NE5532, MC33272, opa627

I seem to agree.
A few recent projects allowed me to roll opamps, when I installed the OPA1656 I never removed it. Neutral and balanced, it just does it’s job and stays out of the way

Good job Vitaly. I am sure you have chosen the best caps for the money. I have Panasonic’s in my 3e 3255 but I changed too many things at once to make any comparisons. Really looking forward to listening to the AllInOne. My case build is going very slowly, it is a lot of work and I have been putting it off.
