Original site is http://www.nextaudio.co.kr/sub/product/cdt/c-1000.html. You can see more pictures except Korean characters.

If that player works as well as their web site, I'd look elsewhere ;-)

but seriously - this looks interesting, but there's hardly any detailed info on that site, nor can you go and actually find a price. The player listed on Audiogon is not the same unit. It's a kit, different inputs, etc. I can't even tell on the TNA site if that is the same transport. No mention of CD-Pro. I like the looks of it, but if these folks actually want to sell this internationally, they need to beef up that web site a little.

The unit on Augon is a $700 kit, $50 shipping maybe, and then there are some upgrades available. Just email the guy. I haven't decided yet if I should buy such a complete kit only to replace half of what's in it, or to build something from scratch.

Actually, it was a group buy project (cd-pro2 transport) of 2002-2003. I don't know the total price, but the price of case was about $700-800 years ago. I guess the leader of the project has established TNA and he is preparing another group buy and comlplete product.

There were a few group buy site of CD-Pro2 transport here in Korea and a few hundreds diyer participated already. However, all are for domestic users since sites are usually operated in Korean .

I am attaching my CD-PRO-2 Player.
