hi Thomas,

I'm quite happy with my AD1853

Though I haven't got many chances to compare it with other DAC.

Is it K-grade 1702 you're using??

Tube Lover:

Nice looking DAC! Are you using the K grade of the
1702, and have you listened to the regular version
also? What kind of I/V op-amp are you using, and
what have you found in this area? And most im-
portantly, how does your DAC sound?

Thanks!

Is it possible for you to publish output stage schema? I have cd with 4x1702 and I'am thinking about new output stage for it.
