Yes 100n = 0.1 ,that was a typo sorry . Thanks for pointing that out Terry .
Best to stick with approximately 0.1 around dac in my opinion and get the best quality caps you can fit in .When you go bigger usually you have to sacrifice quality to fit them in .
At the moment I am evaluating different caps around the dac. I am beginning to build up a strong preference for copper foils around .1 size I currently have Panasonic PPS copper foil caps in the MSBs and also bypassing these with a .01 copper foil underneath the circuit board .
The bypass is a clear improvement .
These copper foils difficult to source so I am also trying some new old stock ERO Roederstein 0.1uf KP .These are excellent quality film /aluminium foils but still small enough to shoehorn in .
I also have some very high end Japanese Toichi copper foils in 0.1 that I would love to try but they are rather big so not sure if this is feasible .
I am currently using Duelund VSF on the output ,and these are wonderful .
I have been accumulating very high grade caps ,as I feel this is by far the biggest area for improvement in audio gear .My CD94 MK 2 will be testament to that .
There are a few areas that are usually overlooked when it comes to upgrading ,and one of these is the decoupling caps around the TDA1541 , The DEM cap next to the TDA1541 is also important. A copper foil polystyrene cap is perfect for here .There is also a cap that takes the digital signal prior to the SAA7210 decoder in the CD 94 and related drives . These are usually cheap polyester .
My CD is still a work in progress and is very time consuming but is becoming very rewarding with each improvement .My problem now is that replay is becoming so good ,I don't have as much urgency to do the next mod
Its all too easy to just sit and listen to amazing music .
I have the parts to complete the upgrades and then some ,but prefer to assess each upgrade individually .This is the only way to be sure I get every ounce of potential from the 94 .
My current aim is to end up with a showpiece one box CD player .
