Tube Amp, Integrated with "Sub- Out"?

I do miss the bass extension listening to my tubes. Any suggestion on an integrated tube amp in the $3000 or less USED market? I have a simple system using a Highly Modified SCD200 Shanling CD/SACD and driving B&W 705 Speakers. Thanks All!
Antique Sound Lab integrateds typically have subwoofer outputs (at least the latest versions) and the ones I have heard sounded very good. There are a bunch to choose from. Arthur
