I decided to try some different parafeed caps on the amps. I had been using the 3.3uf Solens that came with the eXcites, but when I ran Voltseconds equations posted in this forum I came up with 8uf. I also ran Mikes calculations and that came up with 10uf.
I had some 8uf 1000V oilers in the parts bin so I decided to try them. The immediate impression was much deeper more powerful bass (out of Lowthers!) but rolled off congested highs. After burning in for three days they sound very differrent, the highs are very open, transparent, detailed etc and the great bass stayed. The overall impression now is significantly better than the 3.3 Solens, and what this did to the bass is almost unbelieveable.
Now I want to try some Mundorf Silvers....
