If you are looking for warmth and that is your #1 need, then don't purchased the Duelund,Jupiter, or Vcap. They will not give you added warmth. In electronics the Jupiters would be the best choice of the three for your needs as the non-pancake style CAST is simply too tipped in the upper mids for added warmth. Again, this is in tube electronics with the non-pancake style CAST cap. But even the Jupiter, which is very smooth, will not give you "warmth".
The best choice is the Jupiter HT aluminum in wax which is one step down in price from the copper. I like the flat stacked, but the round is very similiar. It is a warm and very musical cap. Based on your needs I highly reccommend this cap. I have used it and quickly came to enjoy the warm presentation and full bodied personality of this cap. It is a big step over a Solen Fast Cap. Is it as detailed and lively as the Vcap, CAST, or copper Jupiter? NO. Does it have more of a warm, inviting and full bodied character, well yes indeed.
It is by no means thick and dark. It is more resolving than your common Solen etc...and the perfect choice based on your sonic desires.
Merry Christmas to all!
