c-j technical questions

Does anyone know of any tests that show the power out-put of conrad-johnson's solid state power amplifiers into a 4 Ohm load. I'm particularly interested in the 2300, 2300A, 2500 and 2500A amplifiers. I'm also interested to know what the out-put impedance range preceding these amplifiers should be.

What is your demanding 4 ohm load? And again if you tell them (cj) what you are driving I am sure they could provide some direction. You could also as the speaker manufacturer assuming that you are planing on driving a pair of speakers.

I own Thiel 3.6's and my MF2500A had no problems driving them and sounded very good. I did upgrade to the premier 350 and obviuosly it does a better job in all aspects. But I would not be concerned about the 2500A driving your Thiels. Thiels are not nesessarily difficult to drive because their impedence curve, at least the 3.6's, is relatively flat. What makes them a challenge to drive and why they need current is because their impedence curve does dip below 2 ohms at least the 3.6's do over certain frequencies. Difficult loads are when impedence curves bounce all over the place creating a constantly changing load to the amplifier.

Having siad all this I would be more intersted in what the impedence curve of the 3.5 looks like as I am assuming it is similar to the 3.6 which may be a poor assumption. If you have not already I would contact Thiel and ask them.
