I quite agree about setting the levels in Dirac 2.0, it is far from intuitive. I much prefer the method used in the previous version. For me it ended up being a process of trial and error, which is hardly ideal. I'll ask Dirac for some guidelines on how to correctly use 2.0.All in all good review to read
I just changed from a Yamaha 3070 + s1100 11.1 system to a 390 as a pre only + Yamaha mx5000. I ran YPAO loads of times it never sounded as good as I hoped for
the 390 and 5000 have just been put in place and rough levels set, how does it sound ? A) much better than the 3070. more detail in soundtracks and just a nicer sound. Only one moan Dirac V2 looks much harder to understand setting up levels than V1 does
So I am waiting to get some info on dirac V2 and will give it a go, if I cannot find the info I will try V1 and see how that sounds
It would be good if Steve could share here how he set levels and background noise in V2
I don't think you'll have any issues, I know plenty of custom installers who partner the AVR390 with non-Arcam power amps, and Dave1956a is partnering it with the Yamaha MX5000.Excellent review, thanks, I have the Arcam AVR550. Do you have any thoughts on using non Arcam power amps with these receivers? The pre-outs on them are rated at 1 volt, whereas many power amps input sensitivity seem to be higher than that.
Very true it is not good on any product even more so when it is sold as part of "flagship" stuffI quite agree about setting the levels in Dirac 2.0, it is far from intuitive. I much prefer the method used in the previous version. For me it ended up being a process of trial and error, which is hardly ideal.
I don't see why not, the AV390 is just processing the signal. If you're happy with the Rotel and how it sounds with your Monitor Audios, then why mess with a winning combo.Thanks Steve. Excellent review
I am considering upgrading my Pioneer THX LX83 receiver which is conected to a Rotel THX RMB1075 5 channel power amp (obtained when we had a TagMcLaren AV32R processor system).
This powers Monitor Audio Silver 8 floorstanders, Silver 8 centre, Silver FX surrounds and W12 sub, in a 5.1 system at the moment. I've been given the go ahead to have an Atmos system so was considering Denon, Marantz and Arcam.
I can't have in-ceiling Atmos speakers so upfiring or speakers positioned close to the corners or edges of the room will have to do!
Do you think the Rotel RMB1075 will be OK partnered with an Arcam AVR390? I'll try to get a demo with anything I do go for but just wondered.
What if the pre-amp doesn't deliver enough voltage to drive the power amp to its maximum potential? Headroom could be reduced.I don't see why not, the AV390 is just processing the signal. If you're happy with the Rotel and how it sounds with your Monitor Audios, then why mess with a winning combo.
Thoughts if any, on how the Arcam compares to the Anthem MRX 720, differing room correction, but I am thinking overall
Personally I don't think it will be an issue, but obviously without testing the AVR390 with a number of different power amps I have no way of actually verifying my opinion.What if the pre-amp doesn't deliver enough voltage to drive the power amp to its maximum potential? Headroom could be reduced.
The 720 is an awesome piece of kit but I think Dirac has the edge over ARC these days. As to your second question, I address this in detail in the review, but yes they are identical.Thoughts if any, on how the Arcam compares to the Anthem MRX 720, differing room correction, but I am thinking overall
I use my 720 as pre/pro and would do the same if I were to jump ship.
Just very interested right now, I like the idea of Dirac, and this seems an attractive price
@Steve Withers; excepting the amplification stage, are the rest of the decoding and processing components as per its big brother??
Funnily enough, I was having the exact opposite problem.Strangely, I think setting the levels on Dirac 2 is far easier than on 1. When set, it actually works. On 1 I kept getting error messages about the level being too high or too low unless they were absolutely bang on.
As far as I can tell the processing on the AVR390 is identical to the AV860, but as you say the latter has balanced XLR outputs. I'm not sure that's worth twice the price. The Yamaha CX-A5200 is excellent (I've reviewed it for another publication), and has loads of bells and whistles, not to mention balanced XLR outputs. However Dirac has the edge for me when it comes to room correction.Thanks for the great review! Very interesting as I'm thinking about going down the separates route for my main system and the £2k price point is about what I had in mind for the pre part. So this could well fit the bill, but I've got a couple of questions.
You said it was essentially the same, other than amplification, as the 850 -- so how would it stack up against the 860? That's just the preamp/processor and other than the balanced outputs what advantage would that have? (It's double the price)
Also, how do you think it would compare against the Yamaha 5200 as that was one I had in mind at about the same price?
See, speed reading isn't all that it's cracked up to be..................note to self, read more carefully!!The 720 is an awesome piece of kit but I think Dirac has the edge over ARC these days. As to your second question, I address this in detail in the review, but yes they are identical.
I have no issues with my 550 and emotiva power amp, although I have an 860 on order at the moment.I know I keep banging on about pre-out voltage, and it may well not be an issue. But.. the 860 processor specifies that the pre-out voltage is 2 volts as opposed to the 1 volt with the pre-outs on the 390 / 550 / 850.
I was using a Crown XLS power amp with my previous Denon AVR, and it worked great set at 1.44 volts input sensitivity. When I got the Arcam AVR550, I could not get enough volume from the speakers when set at that, so dropped it down to .775 volts sensitivity, and it worked fine.
I am now using an old AVR for the two atmos channels as I wanted a remote control power on/off. The power amps with triggers that I have found seem to have a high(ish) input sensitivity rating, so I have concerns about using those.
I have scoured the internet and asked around, but I cannot find any actual measurements of the pre-out voltage on this range of Arcam AVR's. The Arcam matching power amps are all rated at 1 volt or below. And I did find a measurement from an older Arcam AVR model, the AVR750 and they measured it at 900mV.
Thanks, that's very kind of you. I am sure I will be blown away with your set-up but it might be a bit much for my needs.I have no issues with my 550 and emotiva power amp, although I have an 860 on order at the moment.
Where are you based? Happy to demo if you’re concerned and within commutable distance....I doubt you’d be disappointed.
The AVR390 can drive a 4 Ohm speaker, but Arcam recommend you only use it with 8 Ohms speakers. Mind you they say the same about my AVR850 and that happily drives my seven 4 Ohm MK S150/S150T speakers.Also isn’t there is some talk of it having problems with 4 ohms speakers.
