Beresford 7520 - Op Amp Question

[admin_exported]

I ordered the Bersford 7520 a couple of says ago. Will be planning to use it as a spare DAC/Headphone amp with my Apple Airport Express.

I wanted to order the LM4562NA op amps as soon as possible but not sure how many I will need to upgrade both the DAC and headphone sections? Is it 2 or 4?

Was planning to buy these from Mark Grant Cables as used them before for other bits and bobs ... are there any other / better places that people are aware of that these op amps are available from?

Mark is very good, very cheap and very straightforward as I've bought stacks of cables from him, so I wholeheartedly recommend.

2, they are normally sold as a pair.

Thanks guys.

I also found the old thread.

Ordered from Mark Grant even though it was a tad more expensive than the link posted in the old thread.

I wonder how it will compare to the existing op amp as well as the DAC-XP and my MF Headphone Amp.
