I would recommend you pick up the ground from the same connection that the spdif signal is on.. You will see there is 5V, GND and SPDIF all on the 3 pin connector.. Just make sure you get the right connections.

All done!

Display print?

you mean the LCD readout? - its just the standard JVC one! I kept it in its white plastic holder but mounted that to the inside of the case. LED is the standard one too, just have it coming of the supply after the diodes and through a 20k pot for brightness adjustment.


Thanks for the comments guys. Sounds really really good with Peters NOS DAC. I also made up an 8' BNC>>BNC cable but to behonest I couldn't really detect any difference between that and the 8" long one I was using before (and that was BNC>>RCA with an adaptor into Peters DAC). The case is standard 430mm by about 300mm deep and sits nicely on the rack.

Thanks to all for the help so far!

Crystal mods and output cap mods yet to come, and maybe a replacement of the PS supply with Peters one with all blackgates and MSR diodes. Also need to remove the ferrites from the mains lines.

Fran

The guy who photoshopped it must have a great sense of humor .....actually equally as much as the designer....

o so true
we only have 1 button...

Anyway today I mounted my display...the plan came together...
I can now take it off easily by hand if necessary...

Tonight I spent some time changing that c906 output cap between the original one and the ERO one from Peter.

Its amazing just how much difference this cap makes. With the original 'lytic, the midrange, vocals etc are forward, but not as distinct. The sound is warmer, bit more lucious. With the ero cap its a little more refined, with the vocals having more clarity but at the expense of a little bit of warmth and fluidity.

So I'm still a bit undecided on which to live with. I now know what you went though johnm!! I socketed the position so that I can change in and out easily. I also changed the crystal, but to be honest, could not hear any difference with it. I also added some damping material to the frame of the CD mech, also heard no difference.


So my question for those who have changed out the original cap for others, especially the ERO cap:

Did you notice a burn in time, did you notice what I heard and what did you leave in there long term? I'm wondering if some of that fluidity will come back in with time, or should I move on to another cap?

The C906 should be done last, after the voicing of PS and all the other caps on a main board, and after the enclosure is finalized. I use plenty of BG N's so lack of warmth and fluidity was not my concern. That cap is a final touch, sort of icing on a cake

Some people preferred the original cap, some like MIT RTX.

Hi Fran

I noticed the same sonic changes when removing C906 and the crystal. My transport has been running for sometime and I think you will find the sound improves considerably with time.

I have thought about reverting to the original two components over the last couple of days. I suggest you connect it to you main setup and let everything burn in, when you are familiar with the sound replace and compare.

I hope that helps

Richard

I most definetely second Peter''s advice....only in the completion stage you can judge what your final "" voicing"" will be
