It just shows how system dependant these mods are. I really like the 4032 as I find it has the best control of deep bass. Dont find it fatiguing at all-the 4562 on the other hand was 'lazy' with bass notes.

Completely agree with you about bass control between the two chips. The problem I have is that my speakers are BRIGHT, so they do need a bit of taming, so I've just ordered some OPA2107s to try out.

Have performed the mod to remove the two caps this evening. Initial impressions are good - midrange clarity has improved which has had a real impact on making wind instruments sound more natural. Vocals are more intimate too. Bass also seems more tuneful, that monotone bass that the 4562 has been accused of has eased somewhat. Still not as low and well controlled as the 4032, but a definite improvement.

Leave the space left over from the removed caps clear. I am working on a solution for the 4562 to address its low frequency response.

I just wanna doublecheck here before ordering the op amp. It's the OPA2107AP from Burr Brown i want? Can i use that in the Line out and the 4032 in the headphone out?

Understood. Glad I took the time to completely remove those caps now, rather than just cut the legs. One thing to add after a bit more of a listening session last night.. Piano now sounds sublime. You can hear the weight being applied to the keys. That brought a real smile to my face.

Hi Stan,

Does this mod also 'work' on the headphone section. If not why is that?
