Sony DVP-S7000 modded.

Take a Sony ES class CD player and disguise it as a DVD player and you have the DVP-S7000. This mod takes an already very good sounding disc player and adds in modern Op-amps, high-grade Nichicon caps and a few other tweaks along the way. I don't know if this would be equivalent to the work that mod companies do, but it's a heckofa lot cheaper and sounds simply awesome.

The audio board is removeable! Remove six screws and five wire plugs and it's out. How cool is that :thmbsp:



I basically replaced all the caps with Nichicon KZ's & FG's. The Op-amps were replaced with National Semiconductor LM4562's. The power cord was replaced and a better grade plug was used.

I'll dig around and find some more pics I took and post them later. Here's a pic of the last mod I did. Can anyone figure out what it is?

Replace all 4 ops amps with LM4562?

Hi,

Thanks for the info.

Did you replace all 4 op amps (pair of 5238 and pair of 2114) with LM4562? Do you think this is cheap mod by itself?

You bypassed those filter caps?

RickyM. I suffer from the same s7000 affliction; I've got three units, two with the switches.

I've replaced opamps (LM4562), recapped on both audio and power supply board replaced the power cord with some heavier gauge wire (can't remember off the top of my head) and soldered that directly to the power supply board PCB, all to drastically noticeable affect (I have an unmoddified unit to make comparisons). The one thing I haven't done was the mod that you have pictured above with the missing caps. Can you explain a bit about what you've done there? And what about the 1st picture that shows some things soldered to the underside of the audio board?

Hi Pappas. One of the first things I did was put in those RCA chassis jacks. Even inexpensive ones are better than the factory "gold-only-on-the-outside" ones. This also allowed me to bypass the circuitry downstream of the coupling caps. My 'S7000 has gone through Nichicon's electrolytic, and various poly's in the output coupling cap position. I was reading something about passive pre-amps having weak bass and someone mentioned about output coupling caps causing a phase shift at the lower end of the frequency range, causing a cancellation of some bass. To test it out I used a couple of short pieces of wire and bypassed the caps I had in there. Nothing blew up and the sound got better. Bass was both a bit fuller and deeper and very clean. Mids & highs were more detailed without any harshness at all. So I took the caps out altogether.
Just curious, what plug are you using on your power cord?

Oh yeah, those grey things on the underside of the circuit board are .01uf caps used as bypass caps on the bigger caps on the audio board. Not really sure if they have any effect since I did another mod at the same time.

Hey Rick. I've been following the s7000 threads and the Leviton 8215-C thread over at Agoraquest for a while now (I see that you've contributed heavily. Nice work.). So, I've got the Leviton plugs on two units, plus my Pioneer Elite dv-38a.

Someday soon I'm going to replace the stock RCA jacks, but for the time being, can the same mod be performed on the stock RCA's? I'd like to try that. Sounds promising.

Has anyone done any further mods to these units ?

I d like to use it as a transport therefore is it worth to mod ?

Can I mod a certain section to improve the digital OUT path ?

thank you for any help
