### Sorry, i have to write in English when in office due to my laptop's thai system is out of order ###
The used one in web was sold at 14,000 Baht by one of Kotch's customer who really needs money, P'Pairat told me that it was sold only within 2 hours after the post. If budget is not too tight, i think you should buy a new unit.
K.Pong,
I still cannot find better amp at this price level, so i intend to keep it until i find better one at better price.

My Unison SR-1 is almost 3 times more expensive, still better than Kotch in terms of palpability and lifelike sound but Kotch Mk.II now comes closer.
And if P'Pairat continues to offer excellent upgrade path

this to his customers, i believe most Kotch customers will want to keep it too.
K.idel_hand,
Not sure about proac 125, if it is an easy-to-drive (e.g. 90db sensitivity), it should be fine. But please don't forget "CAN DRIVE" is a big difference from "DRIVE VERY WELL", so just bring your speakers and cd player to Kotch House to audition. Kotch is not a "God Amp" that can do everything, so matching (both in spec and sonic) is still the key. Believe me, try it before you buy it!!!!
