Thank you.No, it does not get hot... runs surprisingly cool.
But still, make sure it has room to breathe!

I'm guessing based on this test I would benefit from running external amps for my LCR which are Theos and Stage? I have the TZ-RX50 powering them now. I don’t listen that loud so I don’t necessarily need more power but wondering if the speakers that can dip under 1 ohm will overtax and shorten the lifespan of the receiver. I’m using all 11 channels for 7.1.4, the other speakers are non-electrostatic MartinLogan speakers. Would I possibly notice any audible difference also with external amps? Was looking at Crown XLS, Emotiva, Purifi, etc.
Is this what you need https://www.audioholics.com/tower-s...theos/listening-tests-measurements-conclusionDo you have the impedance vs freq curve? Dip below 1 ohm is interesting but how bad that is would depend on at what freq. and the duration of the dip too.
Yes - if you have the ML ESL's with the 1ohm dip - you will see noticeable improvement in clarity, soundstaging, imaging from running something with serious current for the Fronts.I'm guessing based on this test I would benefit from running external amps for my LCR which are Theos and Stage?

Thanks. Would I even need a 2502 if I never listen that loud? Would a 1502 or even 1002 work just as well at moderate volume levels?Hard to find an impedance graph for the Theos - but looking at relative, Aerius, Sequel, etc... they all tend to drop down below 2 ohm on the highs...
And they all have a reputation for mating well with power amps that have huge current outputs... a number of people have used the Crown XLS2500 with success with the ML's... 1200W@2ohm and totally stable at 1 ohm... most amps just give up at that kind of low impedance level!
Yes - a 1502 would probably be ample.... I would not choose the 1002 simply because the most basic model has lower specs for noise and THD... from the 1500 upwards they all have the same specs other than power/current.@dlaloum

Sounds good. Would you recommend setting it to .775Vrms, the gain at max and regular RCA cables with the TX-RZ50? I'm going to be using Dirac.Yes - a 1502 would probably be ample....

I use the earlier 2500, not 2502, with 1.4v sensitivity, and it works fine.Sounds good. Would you recommend setting it to .775Vrms, the gain at max and regular RCA cables with the TX-RZ50? I'm going to be using Dirac.
It's a "nanny" circuit...amirm wrote ..... "Anyway, I can't recommend the Onkyo TX-RZ50. If they fix the power handling issue, they may then get a marginal recommendation from me.
Hello everyone.
In regard to the power issue that Amirm discovered, has Onkyo addressed this in any way?
Has anyone experienced any issues that can be attributed to this?
Best regards,

If they use the same chassis as the previous generations (and for power, why wouldn't they) - then it is not massively more powerful than the midrange RZ50.I am waiting for the RZ70 or RZ90.
I do not want to get an amp that could be in protection mode (5W) without any warning about that.
I already have a Yamaha RX-A700 that is far less powerful than my old RX-V1200.
For $×××× I do want a powerful amplification.
There hasn't been an equivalent of the high powered Tx-NR906/876 (and their brethren) in quite a few years (6? 7?)
If you really need high power, or loads of current - an external amp is a better solution!
The subsequent RZ3100 & RZ3400 were Class D - adopting the chassis from Pioneer I believe, after purchasing the brand.The 2015 Onkyo TX-RZ800 and TX-RZ900 were class A/B with AKM DAC.
Let us hope that one of the new AVR will take the same technical choices.
