Hi MRMB
The CAT I owned, still own but it is on extended loan, is an older unit. How the newer units compare with the Supratek Syrah is open to question especially since you have the JL-1 amps. As Ecclectique notes, the Syrah is more transparent and seems more extended along with a sense of undefinable rightness, this is closer to how music sounds. I have also listened extensively to a friends ARC SP-10 Mk 2 in my system and while I feel the Syrah has a much better line stage I have come to the conclusion that the phono stage in both the CAT and ARC is mighty good compared to the Syrah. It should be noted that both the CAT and ARC are well noted for their phono stages and with very good reason. I still have work to do on my analog front end, different ic maybe a Koetsu but it is not where I want it to be. So the final chapter hasn't been written yet. You don't mention a tt so this may not have any importance to you.
I have a Berning zh270 and Bel Canto DAC 1.1 with a JVC 1050 zn as a transport which I have run direct without pre. It is very clean and transparent, not at all harsh but seems to take on a more clinical presentation than with no pre.
With your wonderful system I feel you would benefit by a Supratek but a CAT should also work quite well and I doubt that anyone here can give you a definitive answer. A Supratek would definitely be a great choice if you just need a line stage, you can't go wrong, especially at the price point. If you need a phono stage as well, there are more options and in my opinion the Supratek has serious competition based on my experiences to date. Hope this helps a bit.
