This certianly appears to be tru with TW Acoustic. The Raven One supposedly sounds very close to it's bigger brother the Raven AC.
The materials and bearing design and motor are the same.
And I certainly bet Thom's new Serac will have the Galibier house sound at an extrely attractive price, since it too shares the motor and bearing (i think) from the bigger designs, though materials vary quite a bit, while design parameters (mass loading, ribbon type belt and battery motor supply all being part of Galibier's philosophy)
