Which SS amp, for this C-J noob?

What is the practical effect of that on the sound?

C-J mania for the past few days. I have some options on the table; time to sleep on it, and see what's still there in the morning.

Wish me sweet C-J dreams.

Higher output impedance means lower damping factor. The effect of this varies with speaker impedance curve but almost always results in less controled low frequencies. With electrostatics which have a very low impendance at the high frequencies this results in rolled off highs. With most electrostats this is actually a good thing since they tend to sound too bright in most rooms. The Motif and the Martin Logan CLS is a match made in heaven which I enjoyed for a few years.

Thanks PC I have been a CJ fan for many years and still repair some CJ gear here and there.

There are other CJ forums out there. I don't believe it and haven't seen any.

Still working on my C-J quest. Had some close calls recently, and may still be working on a sweet deal; but I haven't been able to pull the trigger on anything just yet.

Remembering that I'm looking...primarily...for a 2250(a), or 2500(a); what are some channels available, to find used C-J...other than the obvious haunts? (AG, CAM, (fleec)eBay, AC, etc.)

Spearit Sound.

Thanks guys. I see they have a healthy offering of C-J at the Spearit website; but no golden oldies like I'm looking for...lol.

Does the old stuff require a call?

CD, the key is patience. And perusing AG every day, just like scoring the right pair of Dyns. And one can only drive so hard a bargain on C-J stuff because it is in more demand than a lot of other brands; there are usually multiple offers on any notably good piece of gear, as you already have found out. C-J has considerable brand equity, just like Shunyata.

FWIW, MF2250s and MF2500s are actually pretty frequent on Audiogon, again patience and perusing every day is the key; it's like looking for that Koetsu Urushi Vermilion at just the right price, you have to be ready to pounce the day it appears.

C-J PV14s, Premier 14s and PV15s preamps are less frequent but do appear reasonably frequently.

Very likely the best "used" C-J preamp at AG median listing prices is the Premier 17, which generally sells for between $1800 and $2000. While this is $400-$500 more than the median prices of PV14s, Pr14s and PV15s, C-J buyers who know their sh*t know that at that $1800-$2000 price the Pr17 is hands-down the best preamp for "performance per dollar" going, and they tend to sell extremely quickly as a result.

Right now, there is a Premier 17 on AG for $2995, but the seller is on crack if he thinks it's going to sell at that price. OTOH, if he listed it at $1995, it would likely sell in a heartbeat.
