he Jensen totally wipes the floor with the other two capacitors. Above 10KHz there is nothing left of the noise. At 5KHz the noise already dips below 1V (-120dBV).
I don't know about you,but I'll gladly pay 33,- for this kind of an improvement. look
Now we are talking

Where can I get the Jensen caps for 33 ?

PS: What is a T-network ?

PS2: I recently read about the new Acuphase phono and the French mag quotes it has 2 x 22000uF sommthing per channel.

Should I increase the actual value (10000uF) ?

I like your psu !

Where did you connect the coils ? (after the caps ?)

What are the voltage outputs ?

Do you use it to power a salas shunt ?

Sorry for the questions but I have been reading about the jensen 4 poles and would like to know if this arrangement might improve things in my setup.

Ricardo

PS: I tried bypassing the actual 10000u BHC with some ERO and things improved a lot in high freq... more detail and extension, but the sound became too forward.

Well, it looks very good but I do not see the need for coils after the jensen 4 pole caps.
