Why would you want to tweak this?

I'm curious about what you think of this cd player.

I bought one myself recently.

Hi, why not ?

I had planned on getting something more expensive (Arcam), but then thought I'd save the extra cash for better amps and a music streamer such as the Squeezebox 3/Soundbridge. I really like the looks and spec/price of the CD5001 but thought I could tweak it a little. I even thought about using an external DAC.

I'm curious as to how this player compares to something like the Nad 521bee (burr brown DAC).

What do you think of the CD5001 ?

Hello,

I think this Marantz CD5001 player sounds very clear and detailed over the whole range. I am pleasantly surprised about the music it can reproduce from my old cd's. A lot better then my previous Denon DCD825.

But it sounds a bit flat and cold at the same time. It misses the dynamics which I do get from my DVD player and the music in films.

So I thought aswell that this player should be able to sound better with some minor changes. The question is what to change.

I've been looking for the service manual but not able to get it yet.

Anyone with some good ideas?

Max

Yes I agree, this is a lot more detailed than my old Kenwood CD player, but the "Kenny" had a punchier sound....

I'll probably start by fitting Spikes to reduce vibrations and change the power cord for fatter higher quality cable.

Aren't the electronics similar to the Marantz CD 5400 ?

Could we not make the same changes that Marantz themselves have made with the
CD5001OSE ? (I don't know exactly what they've changed though...)

Both cd5001/ose had the same dac, namely cs4392, but the ose version has njm2114 op-amp, instead of njm2068.

How do you know about the OPAMP parts?

Any chance you have seen the service manuals?

Check this out:

Might be worth a try.

The specs of the NJM2068 are even worse than the NJM2114.
