If you are looking for a like-for-like replacement, I will say that I love my PMC DB1i's which I have in the office driven by a Naim Nait 5. They are a little overpriced but you could get them used or B-grade at your price. Like the Tablettes they are stunning for the size, though I think the PMC's better bass gives a more balanced presentation. The midrange of the Tablettes is arguably slightly better but overall, at that size, the PMCs give you more if you are not using a sub. As far as minis go, I might also look for the little Roksan Kandy speakers - they are brilliant and would cost a lot more if Roksan weren't an amp company - a true bargain.
Still, though, you said you were open to small floorstanders or bigger standmounts, so that's exactly what you should do. People get excited about small speakers and sometimes, imaging-wise, they can be quite special. But a speaker is a mechanical device fundamentally and the more air you are moving, the more music you get. Speaker designers must cope with the laws of physics.
I would NOT try to move further up the Response range (e.g., the D1SC or D Two). Not for rock and roll with your setup. If you like ProAc maybe look at the Studio range - very vivid and dynamic presentation. A used pair for Studio 140s - maybe slightly out of reach at your budget - would absolutely rock your world. But I would argue that even a pair of Studio 115s would be an upgrade for your music/room.
I am a ProAc fan but I love PMC as well and I think some of the larger cousins of my DB1i's would be even better for your type of music and your amp. Again, though, the prices are high. But if you could get your hands on a pair of GB1i's - which maybe are slightly more obtainable after PMC's newer Twenty series swept the WHF 2012 awards - they would pair brilliantly with your Cyrus and give you a truly special hifi, light-years beyond what you have now.
One further, less obvious thought for you. I had a pair of KEF Q300s that I moved on to a friend, but I tested them with my Nait, my Pathos Logos, and a NAD 326Bee. This is old news but they are stunning speakers, hugely detailed, great bass, and sounding like they cost a lot more (the imaging improved drastically when I switched in the DB1is, but again, it's hard to beat the bigger bass driver when it comes to scale). The sound that the KEFs put out with the Pathos was just ridiculous - a reminder of how speakers need to be competent, not spectacular, to realise the potential of a good amp. The realism was simply stunning considering they are 400 quid or so.
I'm not saying to buy the Q300s, but it's just a reminder that the newest midrange stuff just keeps getting better, much better. KEF just won POY here on WHF with the LS50s, which I have not heard yet - but you certainly should listen to them. I have not heard the newer Tannoy stuff that everyone is swooning over either but apparently they are within touching distance of the high-end. The Tablettes you lost are true classics, but in today's maket, the mid-brands are squeezing the old high-end guard, and doing it hard. You benefit, but only if you listen to the speaker and not the nameplate.
Best of luck - try to have some fun and listen around to some speakers. When I need to replace a piece I always push to get it done fast, and never to my benefit.
