Sigh....not another "Why are there so many XYX's for sale on Audiogon" thread again.

Because there were so many CJ preamps made and sold. It's just a matter of numbers. The more sold, the more you will find for sale on the used market.
The most significant factor was undoubtedly cited by Jmcgrogan2 above. An additional factor in some cases might be that CJ preamps tend to have particularly high line stage gains, often in the vicinity of 25 db or so. If people move from analog sources to digital sources the typically higher output levels of the digital sources, in combination with such high line stage gains, may result in some systems in having to use the volume control at undesirably low settings (depending also on power amp gain and speaker sensitivity) .

In terms of the number of models, CJ was prolific. I'm not surprised CJ fans like to trade them around.

But @jmcgrogan2 is completely right. Having a lot of them on Agon is no meaning for anything but market presence.

What is more interesting is when a brand is selling for pennies on the dollar used.

CJ products are top notch for both build and execution, plus I have never heard anyone say that it is anything but easy on the ears.
Actually I looked for used CJ tube amps & pre amps for months and found very few for sale. Finally struck a deal with Spearit Sound for new CJ gear.
I've also been eying their preamps for sometime but the large variety of the models they made over the years makes it difficult to pick a "good" model. I'm also concerned about their high gain causing mismatch with my amplifier's high input voltage sensitivity.

CJ is a very popular preamp with great sound and great resale a wonderful sounding unit been around 40 years.Any more questions??

My initial thoughts exactly.

C-Js solid state preamps get less attention than their tubed units but I wanted to point out that I've been using a solid state PF-R preamp for a couple of years in my family room system with great success.  It replaced a high quality passive preamp and I lost little detail and gained a nice robustness to the sound.  Just an excellent unit.

Good question... i have a Classic 2 SE and it is the best sounding pre I've ever owned.   It "just sounds right"  as their slogan goes.   Sure, folks may complain about the high gain and the fact that is eats lesser quality tubes, but with my  40 watt  Quicksilver amps and a high quality 6922 tube it is hard to beat.  The tone and timbre is unlike any other pre I've ever owned.   It lifted the veil and delivered the most lifelike sound I've ever experienced in my home.  In fact i was on the fence whether to upgrade my speakers or pre..... my previous unit, a McCormack RLD 1 was no slouch but the Classic 2SE blew it away, no contest.  

People are quick to rip this pre for its lack of features and no remote but it is truly a great sounding component.....isnt that what's most important in a piece of equipment?   How it sounds...... it is for me
Oddiofyl I have a similar set-up to yours but a vintage upgraded PV9a with a pair of Quicksilver’s, just total enjoyment. It is only one of two systems I’ve had over the years (the other also consisted of a CJ PV5 many years back) where people, not just audiophiles, seem to really enjoy kicking back and listening to the music, just so natural and engaging on everything from classical to jazz to rock. Their products really reflect the beauty and meaning in music.CJ  just sounds right for sure.
+1tubegroover and oddify.  I still use a premier 14 with NOS Mullard tubes.  It is supremely musical however is plenty revealing to the recording.

Likely a combination of things. I used a pv10 A for a decade or more. Great little pre amp.
Recently upgraded to a Classic II.
Poster below hit it on the head. The classic's high gain output has necessitated ordering an attenuator. Recommended by CJ tech support.
I am using a Krell KST 100.
Attenuator will go just before amp. Trying the minimum 10 decibel model. Roughly fifty bucks at Needle Doctor.

A pretty decent sale going on with Spearit Sound as those guys approach closing their doors. Happy Listening!
My last amp's input sensitivity was to low.... the Quicksilvers are just a better match ... 9 o'clock on the volume control used to blow me out of my chair like that old Memorex commercial....  the Mid Monos are lower power and take more input to reach full power so all is well
