Hey Doc, looking at the Dynaudio Audience 42 specs: 4 ohm, 86db sensitivity, the A40's ought to be able to drive them to good levels without any problem, or not? And the Eastgate dac has variable output so it can DI into the monoblocks.
A question of synergy?

Start with an understanding that all specs are bollocks, they don't help you apart from in gross matching. If it is louder with the Royds then the amp is not liking the speakers. If the finned top of the amp is getting hot to the touch then the amp doesn't like the load. If there is a halo type distortion around piano notes then the amp is latching up as it doesn't like the load and it will not get loud as the power is being drawn to the instability.

NVA amps are matched by customers with many Dynaudio models. They would not be my personal taste, but there should be no problem.

Looking at the Eastgate Minimax dac (nice!), it has 2 output modes: 3v tube or 2.5V solid state. Would this make a difference?

Some CD's are mastered at differing volume levels, so you can expect a loudness difference between albums.

Sorry, couldn't let this go, had a long day myself and its midnight here.

With both on switchable inputs it works fine and my A40's have more than enough power to drive Magnaplanars.
Yes, my P50 + A60S drive my big Carver Platinums very sweetly indeed and loud as you like, although they're normally plugged into the Royds. I did look for a pair of Magneplanars a while back and may do so again at some point but the price difference between USA original prices and UK prices for anything of recent vintage is a bit much to bear as a matter on principle.

But in terms of the actual speaker masterplan, is there anyone within spitting distance of the M40/M4 corridor who has a pair of Cube 1s in an NVA setup that I could come and have a quick listen to anytime in the next couple of months before I decide to buy a pair?

Ok Doc just to let you know the amps dont ever seem to get hot, I think I am confusing myself with volume and bass, I am in the younger generation on this forum (29 years old and just a baby lol) and I was kinda brought up with a love of bass, (but not to much as its not all about bass) the point being when I listen to the Naim it does have a deeper but less clean bass. The thing with the NVA is that it is so clear and enjoyable, the seperation is perfect but I feel I would like a bit more bottom end, if it had that for me it would be perfect. I have tried various speaker positioning but still cant get the room a little bit shakey like with the naim. But I dont have the clarity with the naim, which is what I want.

Would upgrading to the A80s make any difference ? the price I could get for the Naim would allow me to upgrade. The NVA stuff looks so much better aswell.

Forget what i said about the bass, What would be the difference in upgrading to the A80s ? i had the Naim upstairs warming up all morning and just put it on and its not really what I expected after a week of listening to the NVA. NVA hands down

Should that be "NVA wins hands down".

Change to A80 will be improvement all round, but mostly in bass. BUT your cost effective upgrades would be with the interconnect and speaker cable. LS6 and SSC or SSP.

The other thing to consider is SA on the pre-amp.

Yes Doc, to be fair to the Naim although it isnt as clear and defined as the NVA ,it does have some what of an involving sound but fatiguing.

Sorry about the spelling and english lol
