A numebr of my friends having listened to my modded CD63 (not MKII SI) they were so much impressed by it had requested me to carry out similar work for them. So far I have already promised three of my friends to do the job but on the condition that they have the patient to wait for months as I will carry out the modding when I have no other things to do. Don't be mistaken I will only charge them on material costs and I am not doing this work for my living. Carrying out the work on 3 units I think will keep me busy for a few months

I have 4 of those Mundorf caps on my DAC now. They take an obscenely long time to discharge after power off. I haven't timed them but it must be more than 20 seconds.

If you are getting the mundorfs they will be 25v but the Panasonic tsup's will be 16v.

I prefer the mundorfs but the tsup's are great value for money.

The caps after regs should not be FC's. I use a mix of BG and oscon sepc in my own player but favour Rubycon ZLG 470uF on analogue and Nichicon 330uF solid aluminium where budget is an issue. I also use large value Rubycon ZL or ZLH (1800uF) for the big cap after the main 5v reg.

There are arguments for smaller values for local decoupling, but interestingly, if you look at meridian kit, the prefer larger value local decoupling caps often using multiple 1000uf caps post reg with 470uf close to supply pins ( definately true in the 200 series equipment)
