Marantz CD63 & CD67 mods list

[6h5c]

And here are some scope graphs, just some highlights:
33.8688MHz output at point T1: measured 9.0ps jitter. My 24.576MHz Flea does 8.9ps here. Not too shabby!

[6h5c]

This is the 16.9344MHz version, with 13.9ps it's a bit higher, but who's complaining?
Nice stable waveform, duty-cycle is nearly 50%.

[6h5c]

And this is F/2 for the 16.9MHz version: at 8.47MHz measured 12.5ps jitter, great for servo clocking.

Hi Ray

Looks like brent has another winner !

Yesterday I had a long talk with Ken Ishiwata and after explaining the mods done in my CD53 he told me I should try discrete regulators.... I told him about brent´s Spower but he did not know these.

In the end I asked if he liked files and he answered yes if these are WAV.

He does not like PCM and devised a special kind of dac that does not use fixed 24bit words.... floating number of bits is better he claims and that by itself would take care of file sizes without the need for compression.

I then asked him about caps... He considers ELNA Silmic II to be even better than BG and uses Silmic or cerafine depending on the location... In the end told me to be very carefull about nonpolar caps...

It was a very informative conversation indeed.

He was in Cascais presenting his last SACD and Amp during an Audio Show that I attended.

I was invited by the organization so I could set a meeting with him.
He knows about this thread but does not know the enormous work that has been done.

Cool . He was in Holland too a few weeks ago, but I missed the presentation.

Funny, I happen to have my eye on the Elna's as a replacement for the obsolete BG's. Seems that's the way to go then .

I have been experimenting in my riaa and Silmic II work better than BG nonpolar there.

The only position I still need a BG std is on the shunt vref.

Compared to BG, Silmics lack detail IMO. They have nice tonal info, but seem shut in in the upper mids and treble to me.

The best alternative I've found are Rubycon ZA, they have similar detail levels to BG FK, although they can sound a little "dry" and aren't to everyone's taste. It isn't really an issue when using good regs though.

A nice combo, is a large Silmic after the reg, and then ZA close to the load.

Cheers, Lee.

I am using BG at the shunt output and Silmic at the load..... works wonderfully.

ZA do have trebble extension and quietness as BG but lack the wonderfull extended bass.
