No problem. Make sure you get the LM4562NA.Originally Posted by mwahahaha
Cheers Trailer much appreciated.
Think I might start with giving some LM4562's a go and see how I get on from there
Cheers

LM4562NA for the 7520 and LM4562MA for the 7510 - just to be clear.
Any news on the problem reported with the THS4032 - I am waiting to buy one.

I's still awaiting some feedback on the problem - I am living with it at the moment as the sound is so good, but it niggles and is a bit distracting.

Have you both got the Pin4/8 cap fitted?

Ok, I'm getting some 4032's next week.
I've been listening to the 49720's again this afternoon. That's 48 hours in the 7520 now.
Firstly things seemed to have changed for the better. A definite improvement on the 4562's. Bass is deeper and there is much more detail and clarity of individual instruments. Not quite as big a soundstage but I'm being picky on that one.

Just a suggestion (and I know nothing about electronics)-could you get hold of another THS4032 and try it without the capacitor. That would tell you if its been damaged by heat when soldering or possibly a dry joint is causing the crackling.

OK, that's a thought - I have a spare chip and some BrownDogs - I'll give it a try. As a matter of fact, if I swap the two opamps around, the crackling gets a little worse, which could suggest one of them is a bit iffy.
Thanks for the suggestion - I'll keep you posted.

I will also roll in a LME49720HA to find out the difference with the LM4562HA.
I saw this seller on ebay.
'We recommend using Black Gate (or similar) capacitors on the power rails for these opamps'.
I wonder if he means connecting pin 4 and 8 with the fore mentioned cap.
