The Palladium 1K is identical electrically to the Palladium 2. I owned a pair of the Palladium 2 and they are a very good sounding, power house amplifier. They were the full mono version of the 8008 BB, and a better sounding amp, IMO. There is a pair of 1k currently for sale, but they are WAY overpriced. The seller states list price of $10,000 when in actuality they were listed at $6,000. I would not pay more than about 40 percent of the original MSRP to include shipping. At 40% they would need to be pristine.
