Default Denon DCD1500

Just found one of these at a thrift store. I want to tinker with it. What should I do to modify it? I'm going to start with the power supply by recapping it. Can I upgrade the op amps and dacs? If I can what will work in it?

Thanks,

Ed

This CDP from 1986 (mine is that old but works still after so many hours at work) has small potentials to be tweaked. The major drawback is a 7-pole (or was it 5?) LC-filter in a tin can. In 1986 the CDP was realy cool with oversampling but times are different now. The CD has one good property: Can handle scratched CD's rather well becuase of the slow laser pickup.

Too bad it wasn`t a DCD-3560, that`s a killer-drive!

But the DCD-1500 shure can be improved too. Uppgrading trafos gives more than changing caps, start with analog-supply.

But the easiest way to uppgrade is to add a set of extra
RCA`plugs on the rear, localise the out-signal on the op-amp(s) and just run the signal from there(bypass).

Another simple uppgrade is to add a solid-core powercable.

Ok, that`s a good start

That`s the funny part, if you don`t have a service-manual you just have to searc for them. I`ve used to do this with my system "playing", on low (!) volume, with a thin/soft little cable connected to the output you can take a "tour" inside your player searching for the best sound

Sounds scary? Just remember to do the ground-connection before you start searcing your op-amps!

Good luck!

PS.
Mybe you should write a letter to your family before doing this, just in case

Let the DCD-1500 rest in peace or have it at work or something.

Well,I have a DCD1400 that does not read the disks in one end of the house but works perfectly in the other end of the house.And this is not a one time affair.I've tried this many times.Soon as I relocated the player to any other rooms in my house it stop reading any disks. Soon as I brought it back to my work bench it works without problems. The electrical outlet in my work bench is next to the fuse box.I've upgraded the output stage for this player. Anyone experienced such problem before?
