Dear Dave,
Thank you for your kind reply. I have found a Ayre K1 for sales in our 2nd hand dealer which cost about US$3400. And the Ayre's distributor in Taiwan has been changed, therefore, even I have intention to buy K1 for upgrade to K1XE, I think there is no chance here in the far East. Also, I have concern that the audio gear with ages might got problem easily which need to send for fix. Therefore, I am trying to find a higher grade Accuphase pre such as C-2800 as 2nd hand or the new C-2420 both are from Accuphase with different grade.
