Tube amp recommendation for Gallo Reference 3's

To Jeffreybehr: The NAD S200 is rated at 225 wpc into 8 ohms and 450 wpc into 4 ohms. It is a member of the Silver Series, NAD's first foray into high-end audio, which never caught on.

To Jeffreybehr:
Thanks for your suggestion. I checked out the ASL Hurricanes. They look really good. I really like the idea of not giving up the power of a SS amp. How would you describe them tonally? I am not worried about bass, since I have a Gallo subamp for the second coil on the Ref3's plus a REL Storm subwoofer. Can you describe the midrange and high end? Do they have that midrange liquidity that I miss with my NAD's? Also, how well do they image? How hot do they run? I understand the bias needs to be set quite often. Is this a prob?
Thanks!!

Jeffreybehr: I am really put off by all the reports of problems with the Hurricanes. Especially since there is no factory in USA to support them.

My current system includes a ModWright 9.0SE preamp and C-J Premier 12 monoblocks driving Gallo Ref3's. I am using the speaker-level output from the Premier 12's as input to the Gallo Sub-amp driving the second voice coil. This is the best-sounding system I've heard anywhere! All the advantages of a high-current solid-state amp in the bass (punchy and tight) with the glorious mids and highs of a great tube amp. Sound-stage depth is spectacular. Also, the sound is very well integrated. If you did not know you would never guess that the speakers are bi-amp'd.
