Parts came in today.
I am testing sound wise the more broke in Ampohm. I will test exactly when the silver wire is installed in second speaker. Listening to Tchaikovsky just a huge difference.
On Jimmy's website there is a comment from a new CAST owner saying
"It sounds dull,no dimension, small soundstage.
Thanks,"
I can understand where this person is coming from the CAST are a shockingly low resonance cap. They do not add anything I can hear of, to spice or colour things. I actually went up to hear if the tweeter was working. (and this was compared to VSF)
The Duelund parts have eliminated a few hundred pieces of vinyl I had. They can make the upper freq so clear it amazing but this will also show when the source is not good. You have no doubt.
What is good about low resonance cap.
1 Very dynamic.
2 Quiet, much less noise
3 Tight, accurate, sound with solid bass.
4 Instrument separation and accuracy
What is not so good about low resonance cap
1 reveals upstream weakness. (such as worn vinyl or digital harshness)
2 No echo to smooth out sounds
3 Does not give a added air to sound like high res caps.
The huge downside with high res caps is the resonance, yes can add fullness to the sound of some instruments but this is not done uniformly just at the freq of the resonance. This is done at the expense of upper and lower freq. in my experience.
I can not get the stock wire out fast enough. So it will be out tomorrow.
