The information is a bit inconclusive. The Slant Series was not exactly Apogees glory line, they were made for those who wanted a taste of that ribbon sound but could not afford the real Apogees and the electronics needed to run them. A great speaker from the hybrid line was the Centaur Major with its 5 trace ribbon. There is a Auriga S inwall Apogee at Audiogon that would sound stunning. Remeber that those ribbons are way bigger then in the Magnepan MG 20.1 and have more resolution and speed. Ribbons do love power tough ;-) These ribbons do not come from the Slant Series and have 3 traces like in the DIVA for instance, just a bit shorter.
