Biggest draw to Arcam is Dirac Live, Arcam fans would add its sound signature also.
Here is a comparison of the two.
https://www.zkelectronics.com/com...x-a8a/usa/ [zkelectronics.com]
Can they even support 11 channels and/or Dirac Live Bass Control?
TBH not sure DLBC would be much benefit anyways, since this has mono parallel sub outs.
As far as fanless setup, that's where having preamp mode on a AVR would be a benefit also.
The new Denon/Marantz( starting with 3800/Cinema 50) offers it independently per channel.
I can tell you on my 3800 with all channels in preamp mode, after a 2+ hour movie I can hardly tell it's been on.
BTW in those so called "facts", you left out that ML starting power recommendations for those speakers starts at 20 watts!
Where the heck did ART come into this!!!
No one finds value in DLBC (including you!), why the heck do you think ART will get any interest.
Especially since you are required to purchase DLBC 1st before purchasing ART!!!!
For the record I never told you or anyone else you "NEED" DLBC.
All I did was point out what Dirac says it offers!
If it feels like I'm shoving it down your throat it's because you keep insinuating DL or DLBM does what DLBC offers ….
It does not, I've posted what Dirac told another poster, posted what Dirac own user manual says(and no there isn't one for specific brands!) and even posted a renowned AV professional that pointed this out, very well!
I suggest follow turnne and his comrades & put me on ignore and I'll try not to correct your misinformation assumptions!
I think English is not your first language (please correct me if I'm wrong). I have dealt w/many ESLs who misunderstand but even they have the capacity to ask for clarification (as I politely did earlier).
My TV also has a 40 gbps port, and I intend to keep it for few more years, but that is just my personal use case.
I will personally save $400 as I will most probably change receiver by the time 48 gbps become a requirement.

Even funnier is the "facts" YOU provided says you only need 20 watts!
So much for the "voice of the customer"!
LOL I believe I have proved you wrong several times about reading comprehension!
When I posted what Dirac's user manual and even underlined what they said about what their products offer!
It's written in plain English and you continue to misinterpret it!!! 🤣
To this point you haven't shown any facts to prove Dirac wrong.
Clearly you must disagree since every time I point out that plain English, all you do claim I told you you needed(never did) to get DLBC or I'm shoving something down your throat and now apparently English is my second language!!! 🤪
BTW the only real difference between DL & DLBM is the latter lets you adjust the crossovers within Dirac.
They both still rely on the AVRs bass management for a sub(s).
It's in plain English in the user manual, just have to comprehend it!

If you believe it does for you, that is your prerogative.
MANY in the past RZ50 posts, stated they couldn't hear whatever you heard by looking at that graph.
As you have stated prior, you need to satisfy "your ears"!
I'm gonna go with the "voice of the customer" wins here, don't you?

60XTi/50XTi
The manufacturer has indicated that for 94dB, 2.83V per meter distance required. I've come up with the following specs to match your 20W example.
V = IR, 9.06V = 2.26A * 4 ohms
Watts = V * I = 9.06 * 2.26 = 20.5W
The 9.06V is good for 3.2 m, which is about 10.5 ft. SPL will still be decent even a bit beyond 10.5 ft.
Motion 2i
The manufacturer has indicated that for 86dB, 2.83V per meter distance required. Despite resistance being slightly higher at 6 ohms, speaker sensitivity took a dive! I've come up with the following specs to match your 20W example.
V = IR, 11.04V = 1.84A * 6 ohms
Watts = V * I = 11.04 * 1.84 = 20.3W
The 11.04V is good for 3.9 m, which is about 12.8 ft. Unlike the 60/50TXi, you've lost headroom above what many consider reference at 75dB the further you get from 13 ft.
Insight #1
Impedance vs frequency curves are not typically public knowledge but in this case, I found one for the 60XTi on the SoundStage website (see attached). At the 325 Hz range (well beyond SW capability so the mains need to play this), the impedance drops to 2 ohms! Redoing the calc for 60XTi:
9.06V = 4.53A * 2 ohms
Watts = 9.06V * 4.53A = 41W!!! (is anyone surprised the power requirement doubled w/half the resistance?)

Insight #2
The curve from Amir that you so quickly dismissed (attached again for reference) says that for a 4 ohm load, the RZ50 goes into a "stealth protection" mode whereby power "clips" to the tune of 30W for 2 channels! Your 20W example becomes useless at the 325 Hz range since it drops to 2 ohms and because I already calculated 41W needed (this would apply to both the 60XTI and 50XTi)! Even if you ignore insight #1, this 30W is only for 2 channels. What about the other 3 channels (especially the Motion 2i that has a nearly 10dB sensitivity drop)?!!!
This is just math and science, man. Any questions?

Hmmm let me see do I need math and science to use my "ears"!
The only question you still haven't answered is how do YOU KNOW the"voice of the customer"(ATPsynthase) "NEEDS a high current receiver"!?
Especially as I pointed out, there are MANY RZ50 owners who disagree with your "math and science" and don't "hear" it!
This is starting to make sense though.
If you used this "math and science" when you said "it's our ears that matter! I'm sure DLBC makes sense for folks w/more than one SW, etc., and that's great...for their situation!" when dismissing DLBC!
I will admit it's convenient to use "math and science" to claim how something will sound especially when passing judgment on what someone else NEEDS!
More proof on how you and turnne are cut from the same cloth!

You only pay for the other advanced room correction it offers if you choose, unlike Onkyo, Pioneer and Integra models.
Keep in mind the standard Dirac(Dirac Live) you're paying for that is rolled into some Onkyo, Pioneer and Integra models does not included their sub/bass integration room correction(DLBC).
It relies on the AVRs bass management for that.
Onkyo, Pioneer and Integra only offer DLBC in their premium models, MSRP starts at $2800 and you still have to pay another $500 on top of that for it.
Only you can determine if that extra cost is worthwhile to you.
