JC3+ With Kleos SL?

65db of gain equates to 1778 times V. So 0.25mV of cartridge output becomes ~450mV.
64db of gain equates to ~1600 times V. The 0.25mV output is amplified to ~400mV.

Unless you’re using a passive linestage, you’re going to end up with ~4V of signal given 64 dB of phono gain, which is more than twice the signal voltage needed to drive any amplifier to full output .

Once again, it seems that the OP had made up his mind before starting this thread. Good for him, I’m off this thread now.

Interesting.  

I said I had not made up my mind in advanced.  If most replies had said the JC3+ would not be suitable with the SL then I would have saved the money and just had the Kleos checked and rebuilt if necessary.  Based on the data and thinking in this thread,  I doubt my setup will have any problem with the SL and as I have stated, I have other phono pres that would suffice.

Some Humans have trouble admitting that their line of reasoning may be faulty.

Y'all hang in there,

Robob, if I read this correctly, you’re using a standard Kleos with JC3+ currently? I have a Kleos as well and want to get a new phono stage. If you do have the JC3+, what has been your overall assessment of it compatibility with the Kleos?
Also curious what table you have it on. 

Thank you

Hey,

Well I sent the Kleos back to upgrade to the SL and am waiting.

The JC3+ works very well with the Kleos.  My only minor complaint is that it may be a touch forward compared to the other phono stages I have had in the system.  It does have depth to the soundstage so the slight forwardness may be due to the lack of coloration or the way many recordings are produced.  The clarity and extended response allows one to easily hear cable differences.  Also,  the build quality of my unit is very good. 

Hope that helps,
Robert
