Actually I am focusing in the digital section only because I am using an external DAC (the Sony gives a lot more definition and soundstage than the analog section of the CD53).

Can you suggest some upgrades in the coaxial output lines ?
Canging CT01 (0.1uF) to something bigger ould help ?

Oh, yes, you spoke about your DAC earlier, sorry .
The quality of the digital out could be improved with a better transformer; I read somewhere that the standard one is not a very high quality component. Or you could totally eliminate it if your DAC already has one at the input. There's no need for two of them, it's used to create galvanic isolation.

Dunno if a bigger CT01 will improve things, a better quality might help however. I think there's a ceramic in there now.

Regards,

Ray

It's just nice to show the system off to people who understand!

And Adam was in Sheffield anyway. I think I've inspired him to do more CD63 (and other) mods!

You certainly have, so brent had better get his iron warmed up (new job permitting).

Simon's system did sound pretty damn fine, but i think we spent more time talking than listening to the music. I think that shows how sad we really are

My 63 is still on hold until my new headphone amp, switchbox and silver IC's are built. But i have a question about which upgraded RCA sockets people use on the back of their equipment. I know simon uses the maplin 1 ones but ive been looking at some silver plated ones for my switchbox, but as i need at least 6 pairs the cost is just horrific. Has anyone actually noticed a difference between these cheapy ones and silver ones, as my new stereo IC's are using 0.5mm silver wire in the chris venhaus configuration, with a cotton outer covering coupled with yarbo silver plated RCA's and im not sure if cheapy maplin rca sockets on the switchbox will affect the sound in a negative way ??

The 1 teflon-insulated ones from Maplin provided a shade more detail and less grain than the knackered old standard ones on my CD63ki.

I would say if you're using silver wire and plated plugs then you want to keep the continuity of having silver plated RCAs. Or if you get a well paid job then solid silver ones

I'm sure you know to use silver-loaded solder too. It's cr@p but soldering silver will always be annoying.

This is a pretty pointless post but just to let those who care know I have reached 10.06Kgs

I replaced the 15VA tx for the driver ics to 30VA. There is no sag in the raw voltage rails now. The treble appears to be tighter and it seems to offer better resonance in the bass department. As a side improvement the laser tracking is crisp.

VA is now @ 104VA
