FWIW as a price reference I followed eBay Macro-Tech prices for a few months.
Used not under warranty 5000i lows ran from $1,600 to $2,700.
The lowest used 9000i was $1,850 and still under warranty.
I bought one new 5000i from PlanetDJ for $2,236.76 on a Black Friday sale and another new 5000i on eBay for $2,100.00 (came with plug for South Africa :|). The normal best new online pro store prices I found run from $4,300 to $4,600.
You can email crown support a serial number and they will give you the year of manufacture and tell you if it's still under warranty.
The dsp versions, I-Tech 5000HD, record hours used. Forum wonks advise not to get earlier models not ending in 'HD'.

Thanks, useful information. I think the 5000i is overkill for my application -- I don't need all that power -- but I found a refurbished 2402 for $550:

Think that's reasonable?
That isn't a bad price but it isn't a "deal" either.
Didn't realize you could get a 5000i for that kind of money. I heard good things about their performance at the mids and top end but have not tried them myself. The 5002 I have are not that great on top.
Zulugone, do you have a comment on midrange and treble and imaging performance of the 5000i amps?
Still scratching my head. Both the Neo-8's and tweeters can get by with a smaller amp, which means the A-21 really makes sense for the woofers. But then, I want to try separating the woofers, so need another reasonably-sized amp to play with (although I can just wire them together for initial experiments and keep the woofer and mid-woofers equidistant). The only reason for the second woofer amp would be to adjust timing -- I'm not sure a crossover would be a good idea since the panels aren't quite tuned as LF/HF, there's a lower bass segment in the midbass panel.
If you are dropping the idea of crossing over between the bass and midbass panels because of their complementary tuning to perform together as a single driver then you really don't need another high power amp. Your room is small enough so that it can be fully loaded with the power on hand via the A21 and there is little to be gained by powering the bass panels separately. .
In which case you don't need a high power amp but a good quality 4 channels of high bias class A/AB amps rated around the 50-100W range at 8 ohms.
Damn, could have sworn I replied to this when I saw it a few days ago.
OK, so my senility notwithstanding, the reason I need to biamp the midbass and bass is that they probably won't be equidistant.
Of course I could use a 100 watt amp to experiment with and then get a bigger one for the second bass panel if I do decide to split them. Which will depend on whether the split arrangement sounds better than my current one, which is starting to sound pretty good. I'd been eying the little Pass for the Neos . . . not sure what I'd put on the tweeter (or if it really matters, now that my ears are only good to 12 kHz).
Not really as I have little experience listening to different amps and so don't have much of a reference. I would say the Macro-Tech tends to add more detail over the XLS-2500 across the spectrum but I would guess that's just due to the power (relative to Maggie 4 ohms) which is stable to 1 ohm. It's a soft call (subjective perhaps :) ) but I notice this detail more in symphonies and less in say solo violin.
Over time I've heard more variation between recordings than anything else. I notice less 'choral-soprano-screech' with the Macro-Techs on some old favorite CDs but I also hear more bass in the background so that's hard to sort out.
I didn't investigate any of the older Crown amps. Among the discontinued series I recall the K's mentioned often for durability and home theater use partly because they have no fans.
My Macro-Tech i's are noisy running full speed on any power draw...another DIY project to fix that. I notice them when listening to quieter classical like solo guitar.
I found some useful info on a Crown forum: http://www.crownaudio.com/forums/index.php?/search/.
Thanks. I think I'd probably do what Satie is thinkingof doing -- put the amp in another room. Still, the fans are a drawback . . .
The fan within the 'audiophile' Crown Macro Reference (~ 24 years ago) was described as "its noise distracting when listening at low levels".

Yes, the fan noise can be distracting. I have some tricks to take it down and got a spool of new low gauge wiring to allow me to move it to another room eventually.
