Unravelling the CJ preamps


Here is a very simple question. The et5, the CT, or the Act 2 series 2. I have an et3se and would like to climb the food chain.

I can vouch for the Act 2.2 as terrific, with the added bonus of its high WAF; the thing is serious eye candy that your friends will ooh and ahh.  Just be mindful of proper impedance matching to the amp when dealing with CJ tube preamps.
