The Mc352 is one of the best SS amps I liked from Mcintosh and had good synergy with the Cary. I used the stock tubes and found it just a tad bright at higher volumes, dont know if I could even refer to it as bright but found it less linear than my Audio research ls25 mk1. This was just my opnion, enjoyed both preamps and maybe with a little tweaking with cables or tubes the Cary could have been toned. Both preamps easlily outperfomed the C46 Mcintosh preamp they replaced. Put a Joule LA100 on your wish list too, all 3 preamps are affordable and easy to resell here on the gon. Good luck!
