...What I meant was that the Aida's, with their rear-firing drivers, etc are a change of direction, along with a cabinet that does not have its origins rooted in either the cremonan lute-making or stradivari traditions. My understanding of the design brief behind the luito's was to create a SF speaker with more modern components and construction techniques, in part to bring the price down as the hand-made solid timber staving technique utilised on the Cremona and Homage series' could not be brought down to a lower price point.
And the playback of the Grand Piano, well - I'm probably a bit young to put that in context against their older stuff, but my old boss has the Piano's and dynamically the Luito's leave those for dead IMHO
Yikes! Lots of Sonus faber misinformation here.
1) The rear firing Sound Field Shaper was first seen on The Sonus faber nee Fenice. It is adjustable to room conditions and may be turned completely off if one desires.
2) Basic cabinet making techniques used to make Aida resemble much of what is done in previous Homage speakers. The shape is different but the construction more sophisticated even before the addition of the mass dampers and sprung suspension.
3) Your understanding of both Liuto and previous construction is inorrect. Liuto wood and Liuto Monitor wood are the only Sonus faber loudspeakers still made with solid wood staves, incorporating roughly 21 solid verticals per side. On the other hand, Guarneri Homage was the only Homage product ever made of all solid staves. All other Homage and Cremona series side panels are made up of multiple layers of hardwood veneers laid up in a starburst pattern with proprietary adhesives to create a non-resonant constrained mode panel.
4) There have been 3 Grand Pianos. The original Grand Piano is by far the least dynamic of the three. Grand Piano Home and Grand Piano Domus were far more dynamic and had no trouble rocking. Domus could be a bit difficult to drive and position but once you got that right it could really go. That said, none of those speakers can begin to match the overall performance, including dynamics, of your Liutos.
As a point of disclosure, I have worked for Sonus faber's largest distributor since 1999.
