Acapella vs. Avantgarde


I currently run a Cary CD-306, Cary SLP-05 preamp, and Cary 805AE monoblocks with a pair of ProAc D38's (see system). The combination is sweet and involving, but the combo just does not boogie when asked to play a large orchestral piece, by Mahler/Wagner/Shostakovich. When the volume is turned up, dynamics are poor and the system starts to sound compressed. I suspect that the 50W Cary's simply does not have enough guts to drive the ProAc's, so I am considering replacing them with a more efficient speaker. Since most SET afficionadoes love horns, this led me to look into Avantgarde and Acapella.

I live in Melbourne, Australia. Avantgarde is available through a dealer here, but he does not have any in stock. The Acapella dealer is in Sydney (a plane flight away). I am looking to spend A$30,000 - which will buy a nice Avantgarde Duo, or a secondhand Acapella High Violon.

I have read plenty about the dynamics of the Avantgardes, but my concern is if they have horn coloration. Also, how do they image? Are they sensitive to room placement?

Would the Acapella High Violon's be a better buy, considering the pair I can potentially get my hands on have been heavily discounted? I have read that Acapella's suffer from disjointed sound because of the three different driver technologies (plasma tweeter, horn mids, conventional woofer). How much is this a problem? And are there any room placement issues? Given that the Acapella's have lower sensitivity (91 dB/W/m) would I be achieving a real upgrade by moving from the ProAc's?

Thanks Jim, I'll try that. My pre went back to the factory for some up dates. My system will be down for a while. I'll give that a try as soon as it gets back.

I own a pair of AG UNOs and agree with many here, specially regarding proper placement, top-notch electronics (no - you wont save on amps if you get AG - I have been there) and the sub-horn alchemy.

i) AG is quite directional, I am still fine tunning after six months!
ii) AG cables make a difference in the subs, I have tried a dozen, Siltech worked for me.
iii) AG are addictive, whatever I hear, including a friends pipedreams or Avalon Eidoleons, sound boxed and laid back in comparison - (eg. yes, there is an AG "sound").

My next step is to try Magellan VIII subs (thanks for reading this post) - A good friend of mine is comming tomorrow to compare my system with his (Acappellas involved) - will post his remarks shortly after.

Enjoy!

As the OP of this thread I would like to thank all of you for the help you have given. Since I posted the thread, I have had a chance to listen to the Avantgarde Duo's. In a couple of weeks I will be flying to Sydney to listen to the Acapella's.

I lugged by heavy Cary 805AE monoblock's to the dealer to have a listen. I was very impressed with the but with a couple of caveats.

Firstly, the dealer was unable to find a bass setting that made me happy. Either too boomy, or too hollow, or too little or too much. He told me that it takes quite a bit of time to set them up and i'm sure he's right.

Secondly, the horns do not integrate well unless you have the luxury of a large room and you can sit far away from them. Just walking back from the horns, I can hear them just about to start to come together at about 2m. 3m is better, but at 4m they sounded fantastic. The trouble is, I don't have that much space in my listening room. They would have to be flat up against the wall and that introduces its own problems.

Thirdly, the soundstage projected was too tall and not wide enough. I experimented with toe-in which cured the width issues somewhat, but I think the speakers had to be placed further apart than where the dealer had them (1.5m apart). I mentioned to my friend that it was like watching a movie with the wrong aspect ratio.

Apart from these caveats, the speaker really impressed me. I liked the easy sound, the incredible dynamics, and the subtlety they are capable of. I think that all the above concerns of mine would disappear with the "right" listening room and careful setup. Unless the Acapella's in Sydney do better, I will be looking at buying a pair of these speakers.
Amfibius - You did an excelent jon at describing the Avantgarde main sonic characteristics (all fixable) - just a couple of things IMO.

The sub settings will help you integrating the AG sound a lot, it takes time, but well rewarded, and also, check your cable options (AC, interconect and speaker) since they also play a major role here.

As I said, Siltech worked for my system, but I have also heard that Nirvana works well.

From that point, you can play with upgrades, better frames, subs as time/financlals allow - these are keepers for sure.

Regards,

Sounds like most of your issues are set-up issues. I don't know what Jim Smith's view of the following would be, but I heard a pair of the big JBL K2s a while back where the speakers were literally in the corners of the room, on the long wall, toed-in pretty significantly, to aim at a listening position that was about as far away as you are describing, and they sounded wonderful (using my turntable and a small ViVa integrated, which I think is more euphonic than my Lamm set-up). Taking a look at the pics of your room, and how you describe it, I'm wondering if you could experiment a little to get greater effective distance by spreading the speakers farther apart and toe-ing in more.
I would think that the 1.5 m distance that the dealer had between the speakers was not enough, and I agree that the image coheres at a listening distance greater than 9 ft, which I barely exceed in my set-up. My biggest tuning issue was not placement, though, but the right settings on the woofs, once I had the electronics and cables to my satisfaction.
