I'm with audiothings wondering who makes this 990 six pack you're talking about. Especially for 2400 CDN.
Mercenary shows a Hardy Jensen Twin Servo 990 preamp in one, two, three, and four channel versions. All at least 1000 bucks US a channel. A six channel version is not shown but if it was, it would probably be at least 6000 (1000 per channel).
If a 6 channel Hardy exists, 2400 CDN would be a good deal. I'll buy it if you don't.
