Best Used Tube Based Preamp $2k Or Under?

@mbmi The best is AUDIO-GD Tube preamp. They are very musical and a great value.

Best of Luck on the Warranty and repairs, and shipping back and forth if you live in the USA. Here you go, enjoy, "to and fro!"   http://www.audio-gd.com/Warranty-EN.htm

Warranty, reads:

After the completion of First year Repair guarantee :
If the gears have any problems (manufacturing defects and which is not caused by the user), in this case, the customers only pay for both ways (to and fro) shipping costs ,the replace parts’ cost and repair labor charges.


User inflicted problem repair guarantee:
Customers must pay for both ways (to and fro) shipping ,the cost of parts and labor charges.

I would expect that Audio Note should be a great performer, but no remote. 

Everyone's recommendations are greatly appreciated. Thanks to all who took the time to contribute their ideas! 

Underwood Hi-fi offers a real warranty if you buy Audio GD through them. They fix it in Georgia, US.

My first impression on this thread is a used Rogue RP-5.

Used RP-5 just popped up on Audio Mart listing for $1450.
