Preamps suitable for CJ ACT2 Series 2 preamp.

AGree with Onemug. I've had ACT 2 for a long time...always play around 41 soft, 51 normal, 65-70 for movies only (lower soundtrack recording volume).

The YG's have a nominal impedance of 8 ohms and min below 4 ohms at 4kHz whatever that means. I am truly a layman when it comes to technical stuff.

My room size is about 5m x 5m which is 16.5 ft x 16.5 ft.

My previous preamp was a Herron VTSP-3a which seemed to generate a sharper more 'raw' sound when used with the CJ Premier 350SA in conjunction with both YGs and Zens. I did not need to turn the Herron vol anywhere near as high as with the CJ ACT2.2.

I think I had concerns that having to turn the ACT2.2 up to vol no 50 or above constantly would put strain on either the preamp or poweramp and possibly reduce tube life in the preamp.

Hi vmhf,

Not really...it depends on the gain of the Herron...might have been higher than the ACT 2.2 which i believe is 21.5 decibels.

In any event, 50 totally normal for me. The power amp should not be fussed by the preamp either...the power amp will be more fussed by the low impedance of the YG, and my guesss is that the 350SA is up for it without much problem. Good luck and enjoy! If you really want to know the truth...speak with Ed at CJ directly. He is super quick and very knowledge and friendly.

Thanks Lloyd.
You really have been especially helpful.
Will send Ed at CJ and email and see what he thinks.
I think I am looking for an excuse to try out some CJ tubes in the power amp anyway so see how it goes.
Cheers.

Good luck!
