Thanks Martin - I can't see an easy way of configuring it like that though. I may just go back to RCRC....
Tried putting the inductors on the underside tonight - it got worse!
I'm sick of pulling this player apart now - totally bored with it!
Maybe I'll buy something that sounds good to start with.

I hope you have deep pockets my friend!
Brent and I listened to one of the top Naim players when listening to ATC speakers in Sheffield the other week. That might be good enough with no mods. Actually the thing was certainly better than mine.

That's a CD player that won't need modding

Interesting that they've decided to do it like that.
Is that a) so they can use the same tx for amps
b) because one large tx saves money and still works well or
c) because large is better than multiple small ones
Or all of the above...
My clock transformer might have to go internal now as I've failed to remove the noise problem I've had ever since creating the external power supplies for it. Those psus could power the servo section instead.
I've removed my "reg boards" which appeared to be unnecessary for the clock and clock divider. They both just use a directly soldered super reg fed from the external psu. Actually this seems to sound better and it's much neater.
I got some resistors today so I can finish building my discrete output stage this evening

Hi Guys,
Yesterday night I have compared my marantz cd63se ((discrete filter with independet psu,BG caps, +/- 12V raygulator, +5V raygulator for all digital section, 7805 regs for all analog section, BG cap for all decoupling (DAC,servo,decoder), clock hack from martin,scottky diode for all PSU,wima mkp10 for all bypass)) with consonance droplet (my friend) with result :
My marantz :more natural (less digital), more weight (big and bold).
Consonance droplet:bass more warm and smooth, soundstage more neat.....I mean every musics stuff looks fokus.
Anybody help me how to beat Consonance droplet ?
Regards
aquar

This beast?

Reclock DAC and reclock servo. Clock and clock divider must be fed by "super regs" and a dedicated transformer. The player LEAPS forward using this power arrangement. Timing, bass, detail and focus will shoot ahead!

Hi Simonthy,
That's right for consonance droplet, but I didn't find for review?.
Unfortunately, tentslab clock, audiocom etc very expensive from my place, I hope get AD8561 soon for kwakclock apllied and I was studying sulzer/borbely regs for improve all raygulator, offcourse I will use dedicated transformer.
Basicly I am very glad with my marantz , and I feel still have a lot potential to improve again.

There's so much improvement to be had from clocks, power supplies & transformers and nice voltage regulators. Without using wood in the chassis and tubes in the output your player may never sound similar to that odd kidney-shaped one.
It's true that some of the nicest improvements are costly to buy as complete items. I only buy these things occasionally as it's all I can afford.
I might have my discrete output stage running tonight.
The resistors are very large for the board!

Martin - my inductor hum problem....
I rotated one of the inductors on each channel so that the terminals were reversed but it was in the same position.
The hum is much reduced.
Would swapping the other one make it reduce further or go back to how it was?
Is it because:
a) I have made the hum more common-mode so cancelled by the analogue stage?
or
b) The construction of the inductor is such that it is picking up less hum in this orientation?
Presumably if a) it will get worse if I switch the other inductors around, if b) it will get better.
This area of the PCB is starting to disintegrate...

! Look at that thing! A cheap Sony transport & PCB and KSS laserunit! Eek !That means it is not that hard to beat with a decent modded Marantz.
