The Jolida 302b would be perfect (I own one with Arro's -- perfect match). I think the limiting factor for your room will be the speakers, not the amp.
I am running a Myryad MA 240 power amp and a Anthem TLP1 preamp to my Sttaf's and they sound absolutely awesome. I recently upgraded to the Myryad from a NAD system and the difference was night and day. I think it's only now I'm really starting to appreciate how the Sttaf's should've and could've sounded. I know that Myryad made an integrated version of the MA 240. It was called the MI 240. It is 120 wpc but produces enough current to make my speakers really sing. Compared to the NAD which was the same power output, the Myryad just smoked the NAD. One thing I found with the Sttaf's is that try not to surround the speaker with furniture or anything. I found when I had mine set up in my family room (14'x30'), they really opened up. But when I moved the system into my bedroom, where it is surrounded by my bed and furniture, they tend to sound a little "constricted". It was originally suggested that I look for a Myryad MI 120 (60 wpc) but I found the 240 instead. Hope this helps. Good luck in your search.
$400 will get you the NAD C320BEE, brand new. I have owned one for 3 years, am very satisfied with its performance, and at the time I posted a review of it here . I have used it with speakers rated as low as 85db in similar sized rooms with no problems. It would be hard to get better performance under a $1000. If you go to this months's Absolute Sound, their review of the floorstanding Revel Concerta F12 was done using a NAD C320BEE.
The Audio Refinement Complete is within your price range used and is a wonderful integrated. Here's one review from Soundstage and there are a number of others online. A typical used price is around $500.
I don't really know much about Jolida amps but when I read your post I recalled an ad I just saw for a demo JD 1501RC although it is in Toronto, Canada.
They want $750 CAD for it which is probably around the USD 600 you want to pay:
I see some of these suggestions are Solid-States around 50 Watts ...I don't think that sounds like enough power for the totems but I could be wrong.
I sort of am thinking I need to stay around 100 Watts transformer based or around 50 watts tube to get the sttaf's to sing.
I wish there was some place to go to here totems hooked up to various gear ...but I am sort of stuck going into this blind for this first system.
Have just gone through all this for a small system i am putting together for my mum using Arros.On Totems advise I have just ordered a Unico 80, they say its a wonderful combo. Like you I can't get to hear all this stuff so I hope its as good as they say. Drop them a line they seem most helpful.
Well, I finally settled and am picking up a Musical Fidelity x-150 integrated. I was able to pick it up for under $700 delivered so I just decided to go for it. It is an amp i heard with totem Arro's and I really enjoyed it relative to my Integra. Also it is small, clean, and has a remote for the wife. It should be enough for the Sttaf's I am hoping.
I figure its something good to start with that I can rely on and use to enjoy music with. I might still look into tube separates down the road but I need to spend time with solid and tube before really knowing what I want.
