Suggestion used tube amp between $1,500-2,000

Thank you and now you makes me thinking again between Audio Research VS-55 with LS-7(sure will change to better preamp when I have more money) and Carry SLI-80!!!!!. 

Any other suggestion between this two options?

I have an ARC Classic 60 that was recently gone through by a tech I really trust. It used to be my main amp, but is used as a spare now. It sounds wonderful. They go for reasonable prices these days.

Well the ARC and Cary sound are very different. Both have their fans, but only you can decide whether you want the transparency of the ARC or the warmth of the Cary.

Thank you.

Had you looked into a rebuilt H/K Citation 2?

The Citation had/has excellent bandwidth even be today's standards. I mention this amp as it is still a contender and a fellow named Jim McShane is well-known for excellent rebuilds which will challenge any modern amplifier, and they seem to be at the right price point.
