SS McIntosh preamps have a more full bodied sound compared to the Mc tube preamps if that is what you are after. 
I have used Mc and CJ preamps with Mc amps.  CJ should be warm and lush if that is the sound you want...ET-3 should work well output impedance wise.  BTW, the MC452 should respond very well to a good power cable.  This may help give you the performance you are looking for.  Well done ICs and speaker cable will have a major effect on that amp's performance as well IMO.  As always, YMMV.  Good Luck!
thank you maxwaves
i tried tungsol and gold lion with c2300. Very well sound. but sterile with my wilson sophias.

CJ ET3 can be more smooth ?
