But the biggest problem with the K75 was in the lack of highs, not so much on the lows. In fact I would call them rather sweet and darkish. And no amount of bypassing fixed things me (in fact I hate bypassing signal caps altogether). What is your amp's input impedance? Perhaps you need a bigger value.

 

For 22K amp, I found that 10uF had a very distinct effect for the lows with all the speakers I have tested.

 

I tryed  K75-10 2.2 uF at DAC output coupling after DAC there Is 20 K pot, UGS v3, and finally F5 with 100 K Input Impedance

Try k73-16 at 10uF and you will not regret it...

Any chance anybody knows the differences between the various Russian box caps?

 

I'm looking for 2.2uf or larger and there seems to be a bewildering array of variants from K73P-2, MBGO, MBGC, MBGCH, MBGP, MPGP, KBG-P, OMBG, OKBG, Green ones, Brown ones, Silver ones, square ones, thin ones.  Sheez.

 

Anybody?

Hi Mark, I remember seeing a couple of pages on the net on a different forum (I will take a look later see if I can find the site) that match the codes against construction type.
