Find a good used Threshold S500. Great SS amp with tons of muscle and fine tone. Better yet, a much harder find, but a much better amp and still competitive with some of the best available today (IMHO) is the Threshold SA I mono's.
Now for real world advise at bargain prices, find a good used late model Muse 160. Usually sold (when available) for $750 to $850.
Oop's, sorry... you said cold. Neutral is as close to cold as my brain would allow. Why would you want a 'cold' amp and consider what usually passes for cold is a threadbare midrange, upper mid-range brightness, and etched highs, or in some cases an absence of good bass tone.
