Preamps suitable for CJ ACT2 Series 2 preamp.

Thanks for your responses guys. Apologies for my delayed reply as well. Things are a little laid back down under in Australia!

I have two pairs of floorstanders. A pair of Acoustic Zen Crescendos which I have lived with for a number of years now and truly enjoy. They go well with the CJ combo so have nothing to complain about there.

Recently I wanted a different 'flavor' of sound so got myself a pair of YG Acoustic Carmel floorstanders. To put it simply the YG's do not seem to go well with my CJ combo. The music simply does not flow to my ears with the ACT2.2 needed to be turned right up to make the YGs begin to sing. Vol level 50 usually which is halfway.

I should of been a little more succinct in my original post I realized, so am looking for a power amp that could work well with the CJ ACT2.2 and my YG Carmel speakers.

Using a North Star Design CD transport and DAC combo, Jorma Origo speaker cables, JPS Labs Aluminata between CJ amps and Audioquest Sky from source to pre. Power cables predominantly JPS Labs Kaptivator.

Just realized a major booboo in my title!
Not sure if I can change it to give me back some credibility!!

Yes, my CJ dealer suggested I try some tube monoblock power amps from CJ. But not certain if they would have enough grunt to power the YGs. One would think my CJ Premier 350SA would have more than enough ample power but apparently not. Other power amps on my list could be from the Boulder stable or YBA. Soulution and Vitus just a bit too rich for my blood. Although Boulder gear in Australia retails for incredible amounts of money as well...

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.

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.
