It has to deliver 240volt 10-15amp at 50Hz, standard power here.
Which would be more than adaquate for a cd player.

Interferance, noise, spikes etc would have more of an effect.
So just a decent power conditioner could be an idea but even then
the earth in the building could have more of an influence.

ps this may upset some viewers

Hmmm, thinking of a dedicated generator in the garden
Makes the 200kg filter superfluous.

Ahh that reminds me of something I read in a hi-fi mag... Some guy had a boat with an active ATC speaker system on it. The power was of course coming from a large generator and huge battery pack. Needless to say he claimed the sound was superb!

Well I received my VAM 1202 in the mail yesterday. I installed it last night and I am back in business. It was very easy to install it was up and running in about 20 minutes. Now may be I could start work on the FET Stage.

Good job Dave. Will you build on the CDP board or are making my PCB?

I like the idea of the connectors with a simple contact point.
but why did they only do it for the earth connector.

With their discriptions of why the earth contact area can have problems.
the same goes for the centre pin(+).

From what I have read in hifi mags and on forums the center pin of an RCA does not suffer from the problems like the ground does. It apparently makes much better contact compared to the gnd.

Probably why Marantz only used RCA connectors with gold gnd and standard centers. Yes changing these does help I know!!!

Yes, that's the one. And it looks impressive. Kimber/Russ Andrews like Nickel for their phonos.

If someone said I didn't have to pay I'd have solid silver plugs and solid core silver wires I think. They'd be ohno-continuous-cast (not drawn) and high purity of course. And they'd be insulated with something non-plastic, or maybe foamed PE, that seems like a good idea.

But come on, these are wires, let's not get carried away (I know, I'm guilty). Until we've all got power as clean as Brent has in the player we can't justify spending big money on wiring, in my opinion.

It depends on the weakest link in the audio system being,-
cdplayer, preamp, amp or speakers.

Interconnects speaker cables power lines etc are so far down the list.

Yes and no, I believe the interconnect is part of the link.
I have found interconnect change the sound so much from cable to cable. The dearer I go with interconnects the more open and more natural the audio becomes.

You really dont want a crappy standard lead between even a bog standard 63 and equivalent amp, you are veiling the sound so much

Speaker cable also changes the sound but not to the degree interconnects do.

LOL

Ahh! Extra detail and lower distortion with these changed, worthwhile.

Agreed! But something really crappy or inapropriate will muck up the sound to some degree. (like DNM Reson speaker cable did to mine)

Yes, he would say it was good

Enough off-topic malarky for me now.

Theoretically I'm with you. Probably they have tested the results in practice as implementing two pins won't be problematic.
Shall I ask? Asked Philips the other day how long digital info will hold on a Compact Disc. Got a polite answer ( they had not experienced digital information was lost after 30 years...).

silver might be the best for conductivity but buy how much?

copper doesn't look too bad

maybe it's the oxidation that makes high end use gold rca's

allan

I use Cardas silver, shines too

Thanks Jaap
I am looking building PCB's a friend of mine works for a company that designs their own equipment. I spoke to him about maybe getting him to do some boards made if there are other inserted in PCB's. I can see how many I can get and how much they will cost. I will be giving him your lay out tomorrow then he is going to check into for me.
