You use what you like best. We had a member testing some and he was keen on the Wima as a safe widely recommended and logically priced bet, that's all.

Any thoughts?
That's what I use, and an MK-132V in 1M position, like dvb.
I think the money is best spent on the 220R position myself, being in direct signal path.
It is most influenced in the signal path, and resistor swapping in general here WILL yield results in sonic character.
To me, the Z foils are worth it.
I paid about $10.00 each for mine for 4 qty.
I am planning to put some in an F5 signal path to see what happens...

Thanks for the advice Salas and Tea-Bag.

I think I will have a knock out pre combining Hypnotize with the Lighter Note attenuator and the AMB Gamma 2 DAC\Sigma 11 PSU.

Tanks again for the advice.

The final combination of parts could end up individual to the set, we can not foretell what suits best in a total. Silver oil could be too open in a ''fast'' parts neighborhood for instance. I would check out some parts after break in. There is always a higher ''high''.

lol, could not agree more. I will start with the wima and move on from there. I have always been partial to Mundorf so that is why I naturally started in that direction. I also took part in DVB's group buy on the 4700uF PS caps.

What value capacitor is recommend at the output as niether my Aleph 5 or unfinished F5 has an input capacitor? I seem to remember reading this somewhere but can't seem to find it again. Thanks in advance.

2.2uF would work even down to a 20k Zin amp.

Here's another opinion to further obfuscate the issue

There are better places in a circuit to use the lauded 0.22uf Mundorf SIO as opposed to a bypass cap in an LED chain! Besides, when you look at the size of the cap and the space you have on the board...it starts making even less sense. Save that cap for another project!

I've started and most likely will stop with the WIMA in that position. The critical parts are the resistors and Jfet in the buffer circuit, the PS caps (4700uf), the attenuator and I/O section (RCA's or XLR's in my case). Salas has done all the work with the shunt regulated PS so that's nice. I'm using TX2575 for the 220 ohm resistors (matched to 1%), Caddock TF020's for the 220K resistors and either Caddock TF020's or Caddock MK132's for the 1 megaohm resistor. Again, I am building a differential version so matching of the key components in the buffer circuit can make a difference.

Anand.

Good advice.

Thank you sir.

Exact direction I have decided on.
