100,000 sounds a tad high IF it is a used unit. I think you can get a new piece around the same price.
More important, have you heard the Cyrus amps yourself? Their CD players are legendary, but the market reaction to their amplifiers are mixed. Some call them transparent, some call them dry, some call the harsh and cold, and some call them fatiguing.. And, I also think the speakers you plan to pair them with will make a tremendous difference to the sound.
Take a audition and see if your ears like the sound.
Cheers
