I found the opposite! Gave up on the 67SE and went back to the 63.
67 never really let loose, the 63 was always much more interesting.
The difference should be negligible - it's down to what we did to the players IMO. No two modded players are the same.

Hi GLENN2 i know what you mean but i found the 63 needed a lot more mods to get it sound near the 67s sound.

Hi Glen
My biggest grumble is the detail on the 63, also the 67 sounded much more "analogue" after only a few mods.
The 63 really hasn't changed all that much despite changing loads of components and using "better" BGs and tin hat amps.
on re clocking the dac and servo, if it jumps forward i may continue with regs and psu's
As i'm not an electronics engineer i don't understand why the 2 players are so different
The only thing done to the 67 not done on the 63 is splitting d/a supplies, i tried it but it failed to read the disc so put it back to original.
When did you find that "leap" in performance?

Cheers Ian

Three major mods for me were:
1) Clock (Tent XO2 + XO Supply)
2) Regs for each DAC section
3) Regulating the servo amps (already done for free on 67)

For op-amps, I like a toe-tapping sound and for me those LMs (even the tin hat ones) are total pants.
2xAD825 did it for me (although 2xAD8065 was very good, as was LM6172+OPA627). All SMDs.

Hi padman know what you mean my 67 only had the tin hat opamps caps power rail caps and HDAM by pass and it sounded bloody good. But the 63 had all the same mods and it sounded **** till SIMONT fitted me 5 extra power regs and tonight he fitted me a c1 clock but its bit late to have a good listen but the short listen i did have it sounded very good i will let you know my findings. As im interested why 2 simler players can sound so different

Maybe thats what holds this player back??

I thinks it was splitting supplies that really made the 67

Could be right as simon put 4 regs on the dac it made it sound better but then he added another for the servo and to me the one on the servo made bigger sound improvement than the 4 on the dac

The layout around the clock crystal is worse on the 63 too, but doesn't matter when you add a separate clock.

The acoustica clock hack is the best mod you can do on a 63 if you're not actually replacing the clock I think.

Hi Glenn.

Are you still using opamps, or have you gone discrete?

Lee.

I went discrete on the 67, but with a Zapfilter. It made a big improvement, but the 63 with AD825 still beat it in the end. Even the Zapfilter couldn't shake off the slightly constipated sound that my 67 had, and that my 63 never had.

I don't use it anymore - I use a Squeezebox3 and a lightly-modded Dacmagic. To my ears it's better still, especially the imaging, which is holographic. But I digress....
