CAT SL-1 iterations


Just wan´t to know if there are any significant sonic differences between CAT SL-1 MK III and CAT SL-1 Ultimate?

Frankpiet,
In this hobby, there are few absolute truths. I can't prove anything either, but when I was looking to buy a preamp to go with my Berning amp & Merlin speakers, I talked to everyone I could(including Ken Stevens), and asked for recommendations below $4k used or new(including phono stage). No one suggested what you've heard. Ken told me that the improvements going from the MkII to the MkIII were very substantial, and that he strongly advised me to look for a MkIII if in fact I couldn't afford to buy his current model the Ultimate MkII. I concluded from that the improvements from mkIII to the original Ultimate were not that great relative to the incremental costs associated w/the Ultimates.

Many will tell you that Marantz never made a product as good as the Model 9 amps, that Audio Research never made a preamp as good as the old SP6, or that Quad ever made a speaker better than the ESL57. But there are always new models that feature techno improvments. Some ring truer to the music than others, as you well know.
I have tried many other preamps over the years, and have found this to model to be a top performer in its price class, and prefer it to many more expensive pieces. If you are anywhere near Philadelphia, you are welcome to come listen and decide for yourself. Cheers,

Sbank,

How does your Zyx cartridge at 0.48mv output work with your CAT pre? Does it have enough gain. What volume dial position are you typically at?

sbank. thanks for your very kind words. i´ll try to look for a Mk III.

Andrew,
Yes, the CAT has plenty of gain to drive the .48mv ZYX. Prior to buying the ZYX, I used a Shelter 501II that is .40mv. Both were fine matches. I typically keep volume around 8:00-9:00 for about 80-85db.
The CAT allows for on the fly loading via resistors mounted on RCA plugs that connect just like interconnects. I most often use 300ohms with the ZYX, while I chose to load the Shelter at 100ohms or 150ohms.

Frank, anytime. You might want to call Ken and discuss with him yourself. He is quite approachable. Cheers,
Spencer
