G'day all, in my various DIY phono stage projects I've tried a number of different high performance dual op amps and the OPA2134 is a favourite. However I've used the LM4562 in a number of audio projects of late and whilst I concede that it is a very low noise dual op amp, I'm not sure about its 'sound quality'.

It may just be a case of 'getting used to its sound', but does anybody have any longer term impressions about the LM4562? Regards, Felix.

Well documented chip! :D

I'd try it in a heartbeat.

Cheers!

Felix, I see you have shown up here. A long way from SNA. I must take a look at the chip specs. I'm about to build a friend a CMoy HP amp for him to take on the plane. He travels to NZ about six or so times a year and has some very high end ear buds. I have found a little Jaycar plastic enclosure I can just get the prototype brd. and 9V battery in. His build request is "compact". As always, my intention is to use the OPA2134 (as you know my fav. chip). But I should look at others. Where did you get your LM4562 from?

G'day mate, oh I've been here for a while now! I've obtained my LM4562's from Farnell Australia (element 14). Regards, Felix.
