Tube amp for Spendor S3/5 SE


Recently acquired a pair of Spendor S3/5 SE from a Audiogon member. I am an audio enthusiast and mostly listens to Vocals at low to moderate volume. I never tried Tubes and really want to try them. Could you guys recommend me a tube amp in ~$1000 range. Because of easy biasing, i thought of trying Primaluna Prologue One, but i am afraid it will be underpowered for Spendors.

Surprisingly I had excellent results with an Audio Note P2 SE amp (18 wpc) with S3/5 speakers. You don't necessarily need a lot of power with those speakers providing you are not trying to fill a large room.
Avguy and Yogiboy..thanks for the responses. Seems Jadis amps are out of my budget range! I dont have a pre-amp and i am looking for integrated only. Earlier i had nad c325bee and Yamaha streo receiver(i use this with my Usher speakers). I sold my nad amp and planning to buy a tube one. Seems Quicksilver used ones are in my price range.
Rbrowne...my room is 19ftX11ft(with a 10ftX9ft extn to the side...actually L shaped room). So i think its a small room.

And also to be more specific about music i listen to - its mostly male/female Vocals, violin and flute and artists like Bob Dylan and Clapton etc.
Using the Prima Luna Prologue 2 with Spendor A1's. No problem driving them at all.

Best regards,

Rich
