Audio Research and Dynaudio


Recommended Posts

Never really liked the Vsi60 or Vsi75 on Excite, Focus or Contour. Didn't like the Ref75 either. This was all with 120s and don't remember trying once upgraded to 150s. Ref150se was different but I liked it on everything that it had enough grunt to power :). 

Octave valve amps worked well though. I liked the McIntosh Mc275 too. 

Would really have to see for yourself though and depend on what Dyns you have or plan on.

ARC have a class D range that seemed to do well with B&W 800 series that is difficult load... should be fine with dyns.

 

are dyns good with tubes ?

Owned a lot of Dyns  and generally they do not work that  well with valves in my experience .....they are a challenging load . High current amplifiers get the best out of Dyns. AR amps are not known for being high current so I would suggest not a great match if you want grip and control of the Dyns.

I have C2 Plat.  I have run them with my valve McIntosh MC75's and just okay, wouldn't recommend it.  Brilliant with good SS amps,  main system is Accuphase A70 and Supratek valve pre, the Class A amp really reproduces great detail on the C2's.  Before this had them running with a Bryston 4bsst and Ayon valve pre, which was also a good combo but just lacked a bit at low volume, give it some ooph and they came alive.  As others have said I also think they need big SS amps to get the most out of them.

This is the best amp I've heard my Dyns with. They also sounded very good with a Creek Evolution 100A.

That's great to see,  I've been toying for weeks about a new unit to drive Dyn's S3.4 with, which are hungry for power.   

 

Down to to the Hautonga and Hegel H190 although dubious about their soundengine 2 (hard to find anything about it actually working) and the so so DAC.

I had dynaudio confidence 5 and best i heard were with bel canto ref1000m or bryston 4bsst2

 

Im.told the confidence 5 in a local shop sounded really nice with a hegel h390 or h590

I think the Plinius may be a little brighter than the Hegel so maybe consider that. Mine is actually the 9200 which is a little warmer than the Hautonga so I'm told.

Try before you buy (if possible) is my advice ;) 

 

I aim too but if new and not run in, and using so so quality cables on hand, may result in results I hate.   When all I needed was to run it in, use quality connectivity and voila   maybe?  🤔

It 'shouldn't' make that much difference I would think. You will get the general sound signature no matter what. Someone correct me if I'm wrong. @Cafad perhaps?

Ok,  thanks again for thoughts,  appreciated.

No problems at all. My mate Cafad is the amp pro so he may chime in.

That's cool,  I've spent way too much time on this.

 

Plinius are also very hush hush too, its hard to get any idea of any improvements that have been made since Hautonga was originally released.  Meanwhile its easy to see what Hegel have been doing - releasing upgraded models.

@BoxaI don't want to side track you but I'm actually thinking about trying one of these with the Dyn's.

Crazy!!  I was told today to look at the model too,  looks like a cheap copy of something sold in Aldi.

ARCAM SA30 was also suggested but my mate had one and the software issues were agony.

@Boxa Nah it's a damn good amp. No Aldi in MF haha. I've heard they go well with Dyn but no personal experience. They go well with a lot of speakers actually from what I've read.

Even if new you should know if you like or hate it.  If you like it new you will probably like it more once run in, or with cables that better suit your preferences and the rest of your system.  If you hate it new then you may hate it a bit less when run in. 

Running in, and cable swaps too, only exceedingly rarely transform hate into love or vice versa, the changes aren't that extreme. (even though many of us like to claim otherwise)

I run a pair of C1 with a AR VSI75 equipped with KT150. Both speakers and the amp were purchased from new. The Dyns now have almost 2,500 hrs and the amp 1,800. My experience with both is that they sounded 'dreadful' until you reach above 800 hours of use. Now they both sound great with solid bass, incredible sound staging, great dynamic and superb clarity. I think a number of other factors have also contributed to this remarkable change. In my case, the room size, the cables I use (Power, speakers and interconnects) and the upstream equipment i.e. DAC, Streamer, CD transport. I remember testing out a PS Audio Junior Streamer once and it won't play with the AR. The sound was lifeless even after cranking the volume to almost 80%.

I don't have any AR experience, but If looking at Dyns and valves, I'd look at the Special Forties more than their 'serious' speakers, as the S40s are an easier load (min 4.9ohms, but mostly around 8 according to Stereophile). I'm listening to a pair right now, driven by a little Weston Topaz 6CA7, and the result is pretty satisfying in a small room. I'm sure the bigger ARs would have no problem.
