Do you already have an account? I found a service manual for your DCD and see that it’s quite different inside than mybut still there are many similarities. The CC is a dual ultra low-noise wideband high slew-rate operational amplifier. As I didn’t know if they could be replaced, or even if replacing them would help, at first I left them in after replacing all 6 of the op-amps in the signal path 3 per channel. It would be kind of fun to solder in a socket so I could easily experiment with other opamps in the future for comparison.
Given the low power requirements of a typical CD player, and given it’s a digital device up to the DAC and reconstruction filter, it’s unlikely that swapping capacitors unless they’ve deterioratedtransformers, or the datasheeg lead would make an audible difference.
Do they typically all share the same pinouts? Your is the next gen after my SoundOfSoundNov 24, You need a service manual and schematic.

My subjective opinion is that the sound improved. And swapping a dac isn’t a simple thing. Welcome to Surplus Electronics Sales! What about a straight mains cable replacement to a thicker gauge, better insulated power cord, would that really do anything?
You have to give them some time. And I am concerned that changing an op-amp in the digital section might require re-calibrating tracking, focus etc and I don’t have the tools or experience to do that. Bratwurst7sDec 1, Hope that this helps, James. Out of order response s: I have to look at a schematic c4570d your first but am guessing that like my it uses a muting relay and so doesn’t suffer from the issues that muting transistors give.
Maybe due to the better conductivity of the brass over the stock nickel-plated plug? So in this case I can say that there was no risk in replacing them. A nice improvement in any case for about the price of a six-pack. Then I decided to put sockets in the BA filter positions with the thought that I could use them, or replace them relatively easily. Hi onanysunday, I have a DCD and have done a full recap and replaced the op-amps.
Seems like one of the better options is to start by replacing the opamp s I will check what’s in there right now to see if this could be improved by an LM Bells, Buzzers and Sirens. What I didn’t expect was that the low end had a slightly deeper, more powerful sound to it. You must log in or sign up to reply here. We have been in business for 5 years serving academic institutions, c4570d, service personnel etc.

Swapping the output opamp, or the adtasheet components in the reconstruction filter, could conceivably make some audible improvement, but it’s unlikely. And I don’t believe that this is just my ears adjusting to the new sound.
Your short message goes here. It dafasheet an excellent choice for pre-amplifiers and active filters in audio, instrumentation, and communication circuits. It looks fine for audio, certainly not a piece of junk.

I may be showing my ignorance here and I am ok with that. There are some op-amps in the digital sections being used as motor controllers etc and I have kept my hands off of them. We use USPS for our shipping and include delivery confirmation for tracking.
I also have now installed Wima MKS2 0. Fatasheet instance, can I swap out my clock to a faster one without having to change anything else relating to the clock? Discussion in ‘ General Audio Discussion ‘ started by onanysundayNov 21, datadheet Best to leave them as is imho.
I kept the Nichicons in there because I liked how they sounded. Responsive Zen cart dwtasheet by Picaflor Azul. I don’t know what Op-amps Denon has in your unit but the swap to LM’s was a definite, across the board improvement in my player. Shipping usually takes between days, it depends on your location.
The bass and mid-bass fills in, and everything just gets more clear, clean and butter smooth. Daatasheet beyond my abilities to comment on.
So for me they are hands off. We are strictly an on-line business and have no walk-in store front. Bratwurst7sNov 30, I first tried Silmics and then Nichicons.
I also changed the caps in the audio section.
