I have just acquired one off these Pioneer PD-S801s CD Players it’s still in transit a moment so just waiting for it so thought id see if anyone on here has any experience with these looks like a good contender for the Laminator treatment as there’s loads of room inside it

And

Hi Colin,

I am pretty sure my mate had one and it sounded quite good and the build quality the same. I think the emphasis was on the transport mechanism being top notch.

No worries Colin. Got another link for you, although documents 703 mods but lists among others the 801 model.
http://lampizator.eu/LAMPIZATOR/REFE...ioneer703.html

Another link which I can't find now, did mention fitting Burson op-amps to a 801.

colin.hepburn · #6 6th July 2011, 02:31 PM

Yep that link was the one I was looking for thanks
I see from the service manual the op-amps are the NJM 5532DD which I class as bog standard
I would like to have a look inside but that would void the warranty as there is a sticker over the back panel and top cover

so better leave it for a while

The Plan is to recap with good capacitors maybe re-clock it and change the op-amps or add the lampizator using SRPP tube system and 6H6P tubes so a nice project

They make a good transport Colin. Maybe try it with one of these-

Heard one at Owston and it's great for the money. The dac chip is the same family as that used in the Logitech Transporter.

I've got one of those now, and I quite like it. It seems "better" than the last e-bay one I built.

I'm also liking the TDA1541 DAC in a Marantz CD75 that I've stripped down to the bare essentials and using as a top loader.

Next step is a 6n2p valve output stage same as Richard uses.

Hi Ali
Yep that’s another route to consider although the 801 only has a Optical out but I think you came wire in a coaxial out but not sure if i am capable of doing this

You can buy optical/coax converters quite cheap, I got one for my new TV as the digital out is only optical.
