Have owned my CAT for some 8 years now, and had it upgraded to MK 3. the first incarnation was a drag with almost any brand tube at V6 V7 failed at its task.
The MK 3 is much better behaving, i use the Siemens 6922 goldpin at V6 V7 for some time now, with very reliable and great sounding result. also have a good stock of nos 6922 Ediswan, which are great sounding, but not as rugged as the Siemens.
The CAT was and is very sensitive on its tubes.
i never liked any loading on the phono. keep the 47K.
for powercords, tried many but no big results here, so may keep the stock cord. heard many CAT owners with the PS-300 having great results.
always go for an absolute earthing rod in your garden, but this tweak will account for every gear, be tube or SS.
Some dont even prefer the Ultimate over the MK-3, matter of taste.. maybe the only preamp worth consideration over the CAT is an Atma-Sphere MP-1 mk2.
