Integrated Tube Amp Demo

I am beginning the process of an in-home trial of integrated tube amplifiers. Currently plan to compare the Cary SLI-80HS, Raven Blackhawk MK3, PrimaLuna EVO 300, and Rogers EFI-100 MK2. Wondering if anyone has any recommendations of additional comparable integrated tube amps that would reasonably fit into this group?

Any candidates MUST have a supplier that will allow return of the amp after an in-home tryout. For example, I would like to try the Jadis Orchestra Black but cannot find any supplier that allows for return after an in-home trial. 

Not sure it's relevant in this case, but system is Melco N1A Server - Benchmark DAC (digital), VPI Classic 3 - Herron VTPH-1 MC Plus (analog), Bowers&Wilkens 805 D3 Speakers - REL Subwoofer.

Thanks in advance for all of your input.
