Thank you! My previous preamplifier was an early version of CAT SL1 from the middle of the eighties. It began to shut itself off then the powersupply got hot so I started to look around for a replacement. The shortlist included the Jadis JP80 MC and the CAT SL1 Ultimate Mk. II the former being a preamplifier I heard many times during my time in Switzerland and it had been a favorit of mine.
Unfortunately I had no possibility to listen and compare them in Sweden but a person owning both preamplifiers stated in a forum (Audiogon?) that he kept the Jadis because Jadis bettered the CAT in one area but with the Ultimate Mk. II that was no longer the case, the CAT now beeing better in all areas. I listen mostly to vinyl and with my stepup and cartridge it was just about right and with the CAT I just had to replace the old with the new and it worked immediately. Needless to say, the new version was much better: higher resolution and more extended frequencies, especially going much deeper in the bass.
A CAT is made for eternity but after 20+ years the electrolytic capacitors in the powersupply needed to be replaced and after that my old preamp was like new and it is now working nicely in a friends system.
