Question Aleph 3/Marantz CD-63SE Tweaks/DIY

Hi All
I run a Marantz CD-63SE into an Aleph 3 directly (by using the volume control on the CD player) and into a pair of Gallo Nucleus References. I was wondering if there would be an improvement if I ran the CD into an Aleph pre-amp and then into the Aleph 3? I wanted to do some tweaks/DIY and was wondering in which order to go about in terms of the most audible improvement for the whole setup?

1. Tweak the Marantz following what is given in tnt.audio - change to IEC socket, RCAs, clock, etc
2. Build the Aleph pre-map.
3. Currently I am using ordinary power cables and I can make some of my own DIY power cables.
4. Get an external DAC and use that between the CD63 and the Aleph 3.
5. External DAC and Aleph pre-amp.

Which ones would you suggest and in which order?


thanks much
vsr

None of the listed above will give the improvement of building the preamp.You actually haven't heard Your Aleph 3 yet If You are driving it from Marantz CD (maybe with 6V output from Audio Note DAC it could sing ,but no way with it).I advice You to build either Aleph L (excellent match for Aleph 3) or Aleph P,which is a little bit more sophisticated.With either of them You can't go wrong.

For marantz, do a search here, there's lots of suggestions that'll take you further than TNT, also do a search on Audio Asylum's Tweak section (or Digital)
good luck

As I recall the Marantz 63 family of product uses a digital volume control, dropping bits to attenuate level. Having done that particular experiment some years ago (with a modified Marantz) I can assure you a good pre-amp will help things considerably.

The Marantz vol control is digital and any attenuation will result in loss of data bits resulting in poorer quality sound. Every notch you turn the digital volume down from max setting makes the sound worse because it reduces the digital resolution available. Keep the Marantz vol control at max setting.

Also, the preamp is designed exactly to drive the main amp; the output of your CD is not. So I think it would be a gamble whether you could improve on a pre-amp.

For very useful information, DIY modifications and upgrades visit:

Maybe a simple opamp pre could bring some clarification here, as they are relatively simple to build and cost is low. I run my ZenV4 with a tubed pre and it really is better than driving it from my marantz cd48.

Default Modifications

1) Upgrade the clock, mandatory upgrade.

2) Remove all electrolytic cap that are in the signal path

3) Bypass the SE amplifier

4) Change OPAMPs to a dual Burr Brown part

5) All more filtering-power supply caps

I've done this to several SE63 players, makes a big difference.

Unless one particularily enjoy doing the mods themselves, another very effective option is to use an external DAC such as the Meridian 203 Dac7.

These can be picked up for around UKP125 and are excellent for giving CDPs over about 5 years old a new lease of life.
