Lemme guess. The STRDN1010BN3 deal from Buy? I bought a few too. I've got two brothers that will be happy upon their birthdays later this year. And currently a spare set maybe for a sister, if needed. Bummed I bought my DN1010 and S570 earlier as individual pieces and at a much greater outlay. Eh, that's life.
Upfront. This isn't gospel what I'll preach here. It is only representative of my, MY, understanding of what you ask. And my short version in answering. Should you choose to use the Jamo's mentioned? That's entirely your decision. That you recognize and ask, well, pat yourself on the back for that one. Well deserved.

My DN1010 runs warm in standby. Others state theirs runs cool. But "cool' relative to what leaves much to MY imagination. In operation and at a volume my neighbors might object, again IMO, it runs hot. My past Sony receivers ran warm to hot also. Granted, my last Sony ran a bank of darlington output transistors and so ran even hotter. Darlingtons. Rare, I know. But they were my sole reason of purchase. While I haven't yet seen a DN1010 service manual I'm relatively positive the DN1010 doesn't run darlingtons. A quick peek inside would seem to confirm this as I notice less heatsinking.
Why mention heat output you might ask? Because when you lower the resistive load(speakers ohm rating) placed against the amps output section you're effectively raising the current/amp loading "inside' the output section. Thus, the lower the speakers ohm rating vs what spec is(8ohm), it goes the greater stress you'll be placing on internal components, and thus the greater demands on being able to dissipate this heat to maintain stability. And more importantly, operation. Remember, heat kills. So does raising the amp/current influx beyond spec.
Um, the dB ratings on the Jamo S 606 HCS 3 speaker set. This dB rating(not to be confused with a frequencies "dB Level") is relative to how responsive a given "speaker' is to it's input. Personally, were I going to use them I'd prefer a higher dB rating. 89, with 90 or better being preferable IMO. And if I did choose to use them I for sure would set my 3/2 speakers to "Small' and get a powered sub to redirect the LFE channel power needed while driving away from the 3/2 speakers amp section. Thus further lowering the component stress(heat) of the amps output section.
Moral. At low volume levels I wouldn't imagine you to have any problems assuming good ventilation. At higher levels, as I said, you'll be stressing the components beyond tolerable design spec and it very well will answer back sooner rather than later by exacting it's toll on the DN1010. Biting you in the wallet. So be conscious of your listening habits before/while choosing these.
And for the life of me I don't fathom why they have such mis-matched response dB's between the provided speakers in that set. The response dB is logarithmic. Mind you I'm not degrading Jamo in saying so either, only their choices used here in this particular set.
Tough call. Would I? No. Not these.
Budgetary constraints? Start with decent 8ohm L and R's and build from there as money allows.
