Leo,
How do find the 1364's? I'm pleasantly surprised.

I can report that the new version of the Tirna 4032 mod fits in my 7520 with the lid on. They are about 2mm below the lid. Saying that, I've removed the sticky pad and glue from under my amp board and trimmed all the component legs under it as short as I can get them, so even at this reduced hight they may not fit in some people 7520. I'm going to pass this info back to Tirna and see what they say.

Hey!! We know what we're doing! We want the optimal sound for the least amount of money without getting our own electrical engineering degree!

I don't have a 7520 but it works quite decent in another dac I've been trying it in, it went a bit bright with some material,it actually seemed to improve after some running in, sound was quite forward compared to say the LM4562
Certainly not a bad chip!

all you need is a 7520 owner who also owns a scope

I have a 7520 and a access to a digital scope.
Just tell me what I need to do and I'll give it a go.

The detail is excellent. Best I've heard so far. Just need to tame the top end a bit.
