Amp Suggestion for Harbeth C7es3

Any suggestions for budget amps that work with C7s?
I'm sending my Joule Stargates in for a service next month and will need a replacement amp while they're away. I need to spend under $1000. Maybe one of the Pass Alephs? Or budget low power tubes? I'm using only 18wpc now. I don't listen very loud and it's mostly jazz and folk.

Thanks in advance!
