Best caps for updating my VTL 225 mono's ?

I would go with the VTL upgrade as I have in the past. If there are other upgrades they will most likely do them at the same time.

16 caps would be really expensive to do with V/caps. I'm sure it would sound great but! There are several capacitor write-ups you could look at. Jon L. Enjoy the music and http://www.humblehomemadehifi.com/Cap.html is another good one. For cost and performance I would suggest some Obligatoes from DIY HIFI Supply in Hong Kong or the Sonic Cap Gen I. Opinions will vary greatly on capacitor choices but I have used these two and they are both nice. I'm using Mundorf Silver/Oil now in my amp but that would also be very expensive. "But they are nice"

Good luck

From the description you gave of your tastes; a, "paper in oil" cap would probably suit you. Jensen copper foils are inexpensive, and will provide the presentation you're seeking. Click on, "JENSEN", at the bottom of this page: (http://www.partsconnexion.com/t/catalog/CapacitorsFilm.html) Audio Note copper foils aren't much higher in price(bottom of the same page). Here's some info from Audio Note, you might find of interest: (http://www.audionote.co.uk/comp/cap_paper.shtml) Most higher end caps will have the outer foil's lead marked in some way, for proper orientation in the circuit. China/Hong Kong? pffffft!

God bless you. I wish a lot of us could also say those prices are inexpensive.

Auricaps are ok if you're on a budget. I haven't heard anything bad about MIT caps either.
