Mod your Beresford 7520

[trailer]

I did do a post on here somewhere going through the op-amps post Wolfson somewhere on here. Needle/haystack?

Yes I would be very interested too. I have settled on the ths4032 in the std tc7520 after trying quite a few combinations, but am interested in the extra detail and the need for opamp reassessment that you are picking up in the wolfsoned 7520.

Hey, thanks for that.

Can you remember (and this is a big ask ) about the 4562 compared to the 4032 thru the Wolfson?

Unless you have NO life chances are you wont remember, be good if you did though!

Tell me about it!

I'll have a rummage.

Ta.

I found your original post.... for info.

Right as promised some findings:

I thought I'd have a listen to the 7520 with the 4032's as that is what was in it pre-Wolfson. Initially it is impressive but after a while it got a bit tiresome and not really good for late night listening. I had a thought that maybe I could try the old op-amp rolling trick again.
This morning I decided to give the op-amps ago:

LT1364: Less tiresome as the 4032's but with the same amount of detail.
4562's: Smoother with the same amount of detail and I thought these will do.
However, I still had a couple of 49720's to hand. I popped these in and they were even better. Smooth, detailed and VERY natural sounding. Not digital at all, very analogue.

I've been listening to Ryan Adams 29 CD (an old favourite) this afternoon with the 49720's and it really is a pleasure. I'll let them warm up again for couple of days and hopefully they'll get even better.

I'm guessing that the extra resolution(?) of the Wolfson with the 4032's was just a bit too much out there for long listening periods?

Thanks for that Ampusson, interesting stuff.

Seems theres a real need for reasessing the best OpAmp with the Wolfson?

Oh, woe is me, I'm even more confused now !! - and here's me thinking that it was a straight choice between 4032s and 4562s and now: -

I think I'm going for a long lie down until there is some sort of concensus, or maybe I'll ignore the 4972s and stick with Stan's views expressed to different people - I really need that lie down.
Good Night

Not sure about a real need. I fitted the LM4562NA, which is the best choice IMHO. The LM4562HA is superior, but also more than double the price.

I've observed the OpAmps to be system dependant, with sounding good for one not neccessarily good for another.

I'd stick with what Stan says

And I'll stick with your opinion Stan, at least as a Baseline

Snap!! - seen his very last post? - the one posted immediately prior to yours?
