Parasound Zamp v.3 Runs Too Hot


I have a Peachtree Audio iDecco (for sale), running a Parasound Zamp V.3, to Totem Acoustics Arro floorstanders, and I usually play music loud because the system is in my upstairs bedroom. The other day when running my system loud for about a half hour, the amp shut off automatically and the display indicated "Hi-Temp". The speakers are 6 ohms and the amp will run 60 amps into them, so with that said, is there a better budget amp that will run my speakers loudly for a sustained amount of time without running too hot? Is it a matter of 6 Ohms drawing too much current for most amps?

Please give some advice/recommendations for a budget setup.

Thank you.

Thanks for the feedback! I think my budget would be maximum $700-900 used. I have heard that the Totems are harder to drive. With that said, what is a more efficient, 8 ohm speaker that the Parasound I have would not struggle driving? Or is there another "audiophile" quality amp people would recommend for my existing setup?

Thank you, please opine.
Tha Parasound A23 sells used for $500-$600 and has lots more power - and is a much better sounding amp.
The Totems are well regarded, so keeping them is probably the way to go, but they may not be suitable for the Zamp. I've got the big brother to the A23, the A21, and its a great series.
Schubert, how do I know if an amp is stable to 2 Ohms? Any you can recommend used under $1000? Thanks
