I used headphone monitor to audition these little OpAmps. Here is my findings- #1. (LME49720) sounds warm and bright. #2. (4580D) is airier and more open at mid with higher tops than #1 #3. (MUSES02) is more of V shape and sharp at highs, much clearer than #2 #4. (SS3602) is like a combination of #2 and #3, opened up V, not as airy as #2, bassy and high at tops. #5. (NE5532) is punchy bass, V shape with high at tops, warmer than #3 and #4. #2 is my favorite for my taste.
I swapped from LME49720 to OPA2134PA High Performance Audio OpAmp Burr Brown, but they don't seem to play any role in any of the tests. The LME49720 sounded too dull, I had this experience before with an ASUS DAC. I am very satisfied. 👍 Maybe too cheap?... I haven't changed anything on my two ZA3s.
What kind of banana plugs do you use for these cheaper amplifiers? Most of my banana plugs do not fit into your amplifiers, what size banana plugs do you recommend?
NE5532 for my 62 year old ear's. Thanks.👍
My favorites are: MUSES02 and SS3602 😊

How many opamp need to RCA line out for Fosi ZD3 dac?
Thanks.
LME49720❤
Did you replace opamps in both the dac and the amp? Thanks.
The DAC only and with 2 op-amps replaced.

Hello, 4mm ones will fit. Please refer to the link if you need to. bit.ly/4eN5SHi
Hard to tell which is which because of the gaps. Create another sampling were the music continuously playing representing each opAmps.
Thank you for your advice. We will consider it.🥰
What are SP601 speakers
Fosi's speakers😄
Annoying - Muse sounds best on the 1st, 3602 on 2nd, and LME on 3rd 😂
