Well, my CAT preamp has RCA inputs into which I can plug loads to change the loading but the only loads I have are 40 and 80 ohms. I've tried them both and found them to roll of the highs a bit much for me. But, then, there is my hearing loss in the high frequencies. Most of the bloggers I have read relating to the CAT seem to prefer it straight in at 47k. I do wish I had the luxury of remote to compare loading from my sweet spot. Alas, I think I'll be buried with my CAT.
Convergent Audio is a rather unique company. They have no web site and no published email or phone number. I don't believe they even advertise. Ken Stevens is rabidly protective of his dealers and forces all contact through them. Makes it difficult for the tweakers among us. Unlike, ET you can't just pick up the phone and say, "Hey Ken, send me down some loading plugs."
The company was not that way in its earlier days. In fact, I actually spoke with Ken a few times shortly after purchasing my preamp. I'm not denigrating the company. Ken builds a super product. At the risk of alienating others on this thread, the only preamps I've heard that I thought were in the same league are the ARC SP-10 and SP-11. I do confess to have an interest in the ARC SP-20. I need to get down to Atlanta to see if I can listen to one. Purchase would have to wait another year or two for prices on the used market to come down some.
