I have been using the Rega Brio R with RX1s until recently and then upgraded to RX6s so in my opinion Monitor Audios work well with the Rega.
The only thing I would say is that if you have been using RX2s I think you will miss some bass with the GX50 unless that isnt an issue.
Would there be a similar issue with the Cyrus 8XPdQX amp?
I am not sure who this question is directed at or what the 'issue' is but there's no easy answer and it really depends what speakers are used and what levels and 'realism' is required.
These would be for my living room so decent listening levels for 75% of the time and the rest fairly loud (not disco levels mind you) with music ranging from internet radio (during the day as I work from home) to electronica & house music to metal/rock to 30's to 60's stuff (Dean Martin, Glenn Miller, Nat King Cole) etc...
Electronic music, pop and the like often have limited dynamic range, meaning the difference from quiet to loud are relatively small. This gives amplifiers an easier time than say a well recorded classical piece or something similar dynamic (I am generalising) which will tax an amplifiers ability to supply enough volts to reach sometimes substantial peak signal. Low self measured noise helps further.
You can use a sensitive speaker to make up for the lack of relative power in either the Rega or the Cyrus but it would probably be fair to say that realistic, lifelike volume is not on the cards with main stream speaker choices. There is little substitute for ultimate power where that is concerned but then how many people listen to music like that?
Pretty ... and pretty proud of it
We all talk about amplifiers that lack sufficient grip at high volumes for certain speakers. One thing I've tried to get across many times is that its not just at higher volumes that some of these amplifiers lack grip with certain speakers - it is any volume. If an amplifier is driving the speaker properly, it should sound tight and punchy, but there are many amplifiers out there that can't even manage tight and punchy at lower levels.
I'm not saying this is the case with the Brio-R, I'm just making the point that it isn't necessarily just high volumes where the problem lies.
That is so right!
With the Brio R driving the Dyns that some times people talk about them as being difficult to drive, but they forget that the Excite range was design not to be so hard as the other series in Dynaudio range models.
And with that in mind and your post and my ears, in fact the Brio R drive my Dyns with "Grip" and "punch" at lower volumes ( 7/8 o'clock) at 10 to 12 o'clock it sound so alive and natural, full of grip and control!
When things start to "not sound so right" but that depends on the record, might I add, is 2/3 o'clock ahead.
When I don't have those 3/4 hours of listening in the day I kind get depressed, that is how much i LOVE to hear my sistem!!!
Not according to the spec sheets. Please enlighten.
From Stereophile review of Dynaudio Excite X12:
"Dynaudio designs The X12 is the entry-level speaker of Dynaudio's Excite series, which includes three other models ranging up to $3600/pair. The rear-ported, two-way X12 sports a 5.7" cone made of a proprietary magnesium-silicate–loaded polymer (MSP), with a voice-coil and die-cast basket both made of aluminum. The cone's material is designed to offer an optimum combination of stiffness, inner damping, and low mass. This drive-unit also features a longer voice-coil excursion than previous Dynaudio designs, to allow higher dynamics at high volume. The 1" silk-dome tweeter is made with a proprietary doping compound that benefits from a new precision coating process intended to achieve a more natural high-frequency response. The X12 also includes an impedance-correction circuit that is claimed to make the impedance completely linear above 100Hz. This presents the amplifier with very small inductive and capacitive loads; the X12 should be easy to drive for a wide range of amplifiers."
From Dynaudio Website:
"This is also achieved through the finely tuned crossover which, as in every Excite model, features ceramic resistors, air-copper-coils and high quality internal cabling. The impedance is constant and linear over the entire frequency range, thus providing an easy load to any amplifier. "

I'm like you, if it sounds good, regardless of paper specs, then I'll buy. I was only asking the question because you and one or two others have said similar things.
After looking at the specs of all ranges they ALL are @ 4ohms and they hover between 85 & 87db.
Would be good to hear the DM range up against the Excites and see whether there is any noticeable difference. Also the Dynaudio website claim the DM range is easier to place. Again, that's debatable given they're all rear ported and use the similar internals.

I know PP !
My history with the X12 were Love at first hear... I've demo, MA RX1 and 6, Rega RS3 and 5, ATC SCM11.
And there is some thing else that doesn't come in the spec sheet... Our likes !
What concerns me about manufacturers info is they can be misleading. Can't blame them really, cause they won't ever say "these have great tecnology, but you'll need a really punchy amp to make the most of this model..." so on and so forth. I'd rather they didn't mention about the technology and leave the bit about easier positioning or more benevolent to drive. This will, ultimately, come down to personal taste and/or room acoustics anyway.
I would suggest the Brio-R will be fine with GX50s in isolation. I do think what David is saying, put simply, is that side-by-side with a more expensive amp, it may demonstrate a few shortcomings if pushed hard.
MAs aren't the most demanding of speakers, unlike ATC, Dyns etc., But when isolated the combo should sound fine. A dem will confirm this theory... or not.
MAs might not be the most demanding, but if you look at their specs for the GX50 the Brio just meets the minimum amp requirement, which is fairly high at 50w. That's why I said it may be overreaching.

Too true - the same could be said of the RS6s. They suggest suitable amps from 40 - 120 watts. Had the 40 watt A65 playing thru them for years without trouble. It was only when I started auditioning more expensive amps that the A65's achilles heel was highlighted when pushed. It is eased by the 8 ohms and 86db. In truth, the dbs of older MAs is around 90.
Wow didnt expect this post to go down this route AT ALL!
Thanks for the opinions thouhg; been a fairly interesting read
However things have changed now; I think I'm going to go for the Cyrus 8XPDQX amp that I've been offered as a) it cuts down on boxes which I like (means I can sell on the MF M1DAC) and b) it's a damned fine amp; well reviewed and I already like the Cyrus sound from having a Cyrus 8VS2 a while back with some B&W CM5's...
Just need to sort speakers now so will book some demo's and do some driving around when the New Year lands.
Still going to demo the MA GX50s and 100s but will try the KEF R100s and 300s in there as well as B&W CM1's etc..

This discussion is interesting....given the speakers that are discussed here what amplifiers would be the best match.
I am currently in Thailand so choice is limited to the more main street brands (Naim is not here, Cyrus is very expensive compared to elsewhere)
What brands are available, both amps and speakers?
For amps you can find
Marantz, NAD, Cambridge Audio, Exposure, Moon, Yamaha, Onkyo, Musical Fidelity, Roksan
Polk, NHT, Monitor Audio, Dynaudio, Kef, ProAc, Focal, ATC, B&W, Wharfdale, Totem, Pardigm & Spendor (a few models)
Unfortunately a home demo is not in the cards here, they just dont want do it or I dont know them well enough at this point for them to allow me to do it.
Deals are hard to find, prices are generally at the suggested retail level with year-end sales, normally above listed retail. Dealers generally have only one or two brands which makes comparison difficult. That is why I am seeking some advice on here.
Happy new years to all and thanks for your advice.
Depends on prices, but look, at first, to amps like Exposure, Musical Fidelity and Roksan and speakers ProAc, Focal and Kef 'R' series. I'm sure others will have a different view - one has to start somewhere.
My favourites with the Leema is Totem Arros but you'll need a gutsy amp to make the most of them.
Best wishes for 2013.
Well not anymore than with the Rega - this Cyrus is rated at 70w / channel. WHF's review states it only sounds a bit stressed at really loud levels. I think you could test them with the GX50.
