I've just visited Guido's site and discovered a new product:
http://www.tentlabs.com/ProductEntities/CDplayer/CDplayer.html
..in reality I was waiting for the new dac
..but..
It's really nice! Especially the acrilic plane! ..I love this material!!
Guido, any info about it? ..its technical peculiarities?
Few questions:
1- What about the light (sun or -worse- fluorescent) which interferes with the laser? Is the open chassis your ultimate set-up? It's surely more aestetical than a closed box, but IMHO less effective.
2- Don't you worry about the vibrations? ..I see no suspension at all!! I used eight opposite magnets in my player (do you remember it?), it's really effective! Did you investigate about this problem and possible solutions?

The pic in the Dutch article on the player only has RCA's.
And i see only 1 output tube, a Mullard E88CC is very nice though. Small wonder as Guido must have picked up nice bits and pieces from Ed de Jong.
(Way back down in history i wondered if shaving my head as bald as Ed's would get me the g/f-s as exotic and freaky as his, and also 20 years younger.
)
CD-player looks very nice, even for 2.5 big $ bills.

Ciao Roberto,
Thanks for your kind words
The acrylic initially was made for demo purposes only, though I found many people like it ! It is available, though i do not reccomend it, indeed for stray light but also for dust purposes...
A "normal" cabinet will become available too, also DIY. In that cabinet i will take care of the echanical mounting / suspension of the drive.
Ofcourse you can make your own cabinet, all modules will become available seperately.
There are no balanced outputs, I see no advantage in normal applications, but if you want, you van drive a pair of transformers, Lundahl makes some nice ones. There will be 2 output impedances, 2.7k-ohm or <100 ohm, the latter being made by a well linearized FET buffer. The user can choose which he / she prefers.
Yes, I met the E88CC at deJongs place long ago, it is a fine tube, when used correctly.
all the best
There are some updates on the site.

How will the build in DAC (AK4384) of a CDPro2M compare with this PCM1704?

possible loop
Ciao Guido
I see you use the controller\display board from Nico as I do in my player.
I'm working at a deep revision of my circuit and I noted a possible ground loop between the cdpro board and the above mentioned board.
It could be generated by the flat (control) cable gnd connection and the boards own supply gnd connections.
Did you care about it?
Maybe a 100ohm//100nF as a breaker could be fine
Ah, nice case with wood sides! I planned to use it on my DAC!

Re: possible loop
Hi
Yes, these loops often are present. Actually I am not too worried about them, but you may try the suggested network.
