If you are looking at this you probably already know that these are designed by ex Chord engineers and they are unbelievable. This is a completely digital amp and it is the sweetest sounding and most fast paced amplifier I have ever heard. It has all the warmth and rich harmonics of a Vacuum Tube amp but the speed, tightness and control of a heavyweight contender solid state amp. This amp retails at $24000.00, make a reasonable offer on this one. No low-ballers please, this is a top of the line world class amplifier. I listed this once before and an Audiogoner offered me $7,000.00, I am not even sure why he wasted his time writing that offer LOL. You can reach me at 720-620-4440 or just e-mail me through this site if you prefer. If someone purchases at my asking price using the "Buy It Now" option I will cover the shipping and shipping insurance to you within continental USA, this is not going to be cheap! I have the original box, manual, and all packing materials. I rated this a SUPER-CONSERVATIVE 7/10 due to a very small (probably 1/32 " diameter) round defect or chip in the front face plate, down and to the right of, the Chapter Couplet 400S engraving. It is a divot so small I can not get it to show up on any photos except by glare from the flash if I catch it right, but being OCD I know it is there. Even if I pointed it out to you, you would notice it is there only after very careful inspection. It is about the size of a nail point, it is still black and non-reflective, and the rest of the unit is beautifully flawless/mint condition with absolutely no scratches or other marks. The mark is not something you or anyone else will ever notice. But it is on the front faceplate so Audiogon rules dictate it is a 7/10, the rest of it is 9/10 if not 10/10... Buyer pays Pay Pal fees as usual if Pay Pal is used.
Thanks for looking
