Conrad Johnson CAV45-S2 8 ohm? 4 ohm? Other?

Tone Publications has a new review out on the CAV45S2.

Mine has become my daily listener. Giving my CJ ET7 and CJ Classic 120SE some time off for good behavior. I will more than likely do the Teflon cap upgrade on the CAV45. It is so easy to listen to, and I am driving 4ohm 87db speakers.

The CAV 45 is a great integrated amp......  its more like an amp with a volume control .   Stripped down, low parts count, sweet sounding.   If I were to buy an EL34 integrated amp, that would be the one.   

Someone mentioned the EL34s are Sophia Electric EL 34s, well mines have Mullard written on them and look nothing like Sophia Electric and the amp sounds incredible. Like it so much I have no need to ever look at amps again.

Hi, you have Mullard new production tubes. I have a CJ cav45 S2 and mine came with the same Mullard tubes.
 

I also have some Mullard xf2 Blackburn plant el34’s. The xf2’s are better but they should be at $200 each. What surprised me was how nice the new production tubes sound.

 

I don’t use the amp as much as I should but If I didn’t have the xf2’s I could be perfectly fine with the new production Mullard’s. The xf2’s give you a little more sparkle and air and little better bass. I hear kt77’s sound good I just I haven’t tried it.
 

I’m guessing yours came with 2 NOS RCA signal tubes and one new production 6922. That 6922 can really make the amp shine try some amprex, Valvo and others if you already haven’t, it’s only one tube. The Amprex brightens it up Valvo mellows the amp out  more but keeps the highs. Good luck you have a very nice amp.

Sorry I was thinking Warnie7  was OP. OP you can open up amp and change ohms. I run 6 and 8 ohm speakers on 4 ohm tap and never felt a problem. I believe you need to know how to solder but don’t quote me on that. I was ready to solder  mine but never did. Call CJ they will do it for you.  Shep5580 if your looking for one I know where one is in Austin Texas, perfect shape.
