HiFlight (Ron Kerlin) is where I got mine. I bought pre built modules from him, he's a top bloke. You can find his details on this thread as he is also an avid fan of ibasso gear. He's the chap behind "topkits" (premium chipsets for rolling).
It's worth doing though as the 5002 is easily my favourite buffer.
Hope that helps....
Well i just assumed that the buffers were like op amps, so slot right in.
So they need additional dip module, with a resistor in tow.
But after speaking to ron, i think i'll plump for his topkit, it'll come with what im after and them some,
should keep me happily tinkering for quite some time
And like you say ron is a top chap, so i don't doubt it's an excellent package.
Well it's what most with the P4 seem to choose, im enjoying the AD797 it's opened up the sound a treat, so the OPA627 and HA5002's should be rather special.
And if it's not to my liking, at least i'll have others to try.
