Hi Bill
I just replace the Nippons (6 pcs) in my Cadenza monoblocks, with the Tubecap 200uF.
The amps was getting better with the V-Caps, Tantalm, Riken, Mills, Mundorf S/G and DH-Labs wire.
After installing the Tubecap I get a brand new amp.
If you like the sound of these Caps, I will say it is the best caps on the market.
Maybe I can give you a good price on these caps.
