I ran CASCADE through the system again for a couple of hours.
There is a marked difference it is now warm sounding but again the high frequencies seemed louder "again".
The soundstage has opened up.
The soundstage was very strange at first power on so I googled other people experiences with Black Gate.
Someone said it sounds like the soundstage has been compressed in the middle of the speakers like a V and pushed right to the back.
This was my initial impression and its now opened right up. Very strange of course of no consequence now due to black gate being as rare as Rocking horse poo.
Its interesting for me to hear the depth of sound even to what sounds like Sub-bass not always welcome but interesting.
Now some of this is obviously the natural reforming of the caps, but its interesting none the less.
Having used Kaisei in the past and its my normal go to capacitor, I would probably use the non-polarised version.
There was a much quicker time to settle in the circuit.
I tried the IsoTek short play on youtube and after the system sounded warm, however there was not the increase in loudness that seemed to follow Cascade and the HF were not so clear (or so it seemed).NB cascade is a free download. But be very careful if you use it I wouldn't put it through headphones or speakers. But whatever floats your boat
For interest the Polarised version of the Kaisei is not so warm sounding. Its not the same by any stretch of the imagination but think:
Non-Polar = warm mid tones.
Polar = brighter sound.
But both have good detail and clarity.
Just my thoughts.
