Is it Overkill to use Duelund Caps in Power Stage (Counterpoint SA-5.1)

Firochromis · 7th December 2012, 01:55 PM

Hi people,

I have a Counterpoint SA-5.1 pre-amplifier in my system which has phono and line stage upgrades performed by Mike Elliott. He used TRT Dynamicaps which are fairly good.

Now I want to change the power stage caps which are 0.47u at the right hand side of the chassis. My question is, is it overkill to use a Duelund CAST PIO cap (or similar) in the power stage, which I assume, is not in the direct audio line?

Any comments are appreciated...

You mean the power supply caps' bypasses, right? This pre already looks as upgraded as it possibly should be.

If you really have itchy hands rather upgrade the electrolytics

I agree: I don't have a single electrolytic cap in any gear from the output of the CD player to the input to the speaker drivers.

You could go with Mundorf M Tube Caps or Clarity TC series caps to replace the electrolytics, but they are much larger and probably won't fit where the orig. caps are. I would only use more expensive caps as output coupling caps, and even then Duelund are crazy expensive....

Hi, I mean the blue capacitors at the right hand side of the chassis, especially the bigger two. That part of the SA-5.1 pcb is the "High Voltage Regulator" section and the only un-touched part of my pre. That's why I thought I should upgrade them.

By saying "electrolytics" do you mean Dynamicaps?

Electrolytics are the blue spragues....

To substitute the electrolytics Mike Elliot loves Continental MKP film in oil but I believe you don't have spce to fit them. Also Spragues are axial so can't be difficult to change.

We are all rich since we spend the money to hi- fi stuff (which should have spent to kids) and time (which should be given to wife) to internet forums.

Oh, and l may be wrong about which should be for kids and which should be for wife.
