[av-trouvaille]

Above was mentioned the Leaf dac can be found quite easily. Today, it does not seem that easy.
Can you please share what is currently the place to go for a nice offer?

Hi, can somebody tell me what caps are those 16V 220uF? Brand, series? Also those in between the op amps? I have ordered this amp for a price of 150Euro and want to get maybe the best out of it with the change of op amps and maybe changing some of the components if possible for some better ones as an upgrade. Thank you

Seems to be Generic SMD caps (for those in the interface board)
for those next to the 5 OP amps, I see 4x standard Electrolytic Capacitors

If I were you : I will start with the OP amps update to begin )

 

[JoeFPSGamer]

Yes, op amps change will be the first. from your photos I can see some Elna RF caps (4 bigger smd caps by the BT module) but I cant see what are those other SMD caps mentioned in the previous post. also the after buffer op amp caps. I know, that you don't have this unit, but maybe somebody can answer those questions. If not I will write down some parts that are going to be replaced and or upgraded to get the full potential out of it. I have some WIMA caps in mind as coupling caps

Give a try to the OPA2210 (Genuine) , they are modern Bipolar super Beta from TI ! They are just awesome for all around Audio use.

I have some OPA1612 for a test. I don't think, that the OPA2210 is the best for music but I can be wrong.

Give a test ) I have tested the OPA1612 / 1656 / 1642 / Burson Audio V5i, Muse 02 / Muse 03, OPA2210, OPA1622, OPA1692,
I keep on saying that the 2210 is the best for me at least with my amps.

 

[JoeFPSGamer]

If I can get my hands on some, then I will try them, right now I have 1612 for test, some LME49990 and other OPA. How was the stock vs OPA1612 like? a drastic change?

 

[JoeFPSGamer]

And those are Elna RV and not RF caps, just to make it clear

@daniboun what have you noticed sound quality-wise, when you replaced the original power adapter for that Leicke?
