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?

No Amfibius, You are certainly not more insane than any of the rest of us in this hobby. In fact I think you are on the right road with your speaker choices.
Markxiii said it all. The plasma drive on the Acepella's is incredible.
Amps I have used with my speakers include EAR 519, Atma-sphere MA1 Mk2.3 with resister and power supply upgrade and Einstein Mk 60's. I have tried several others but they are not worth mentioning. I love OTL amps and they sound great with Acapella's. I believe the factory uses the Einstein OTL's for voicing their speakers. Good luck.
Amfibius, since your 805AE's are capable of putting out 70 wpc they may actually be OK. Are these Violons the "High" version with a single woofer or the more expensive "High Suboktav" version with two woofers?? The single woofer version is easier to drive, the "Suboctave" model has considerably better bass, but it needs more current to make these woofers moving.

Docsavage, do you mind sharing your thoughts on the Atmas vs. Einstein amps on your Campanilles?
Whatever speaker your considering against Duo's would have to be better than anything I have heard.
When I was at CES last month, I got to hear both the Avantgarde's as well as the High version of the Violons. The Avantgardes sounded good, but was not really my cup of tea. (I have never much liked the horns, either their sound or their looks). Until I heard and saw the Violons. They were impressive. (Too rich for my blood, but if it were my choice, I certainly would consider the high model of the Violons!

My two cents worth.
