I owned Dynaudio 3.3's (the predecessor to your speaker) and ran them in the same room as my Vienna Acoustics Mahlers. In comparison, the Mahlers are warmer and meatier in the mids. Both speakers are open and transparent in the mids and highs. Each Mahler has two 7" midrange drivers (the same 7" ScanSpeak carbon-fiber midrange drivers used in the Wilson Maxx II) and two ported 10" woofers -- they have prodigious midbass and must be used in a large room, away from the walls, so as not to sound boomy. They also must be used with solid-state amps featuring bipolar output transistors (like your Bryston, Sim and Levinson) and stiff power supplies in order to control the two 10" woofers in each speaker, the impedence dropping to below 3 Ohms at various points under 100 Hz. I had best luck with Rowland Model 6 monoblocks (a supurb combo). Sumiko, the U.S. distributor, has used Kimber Monacle speaker cables to demo Mahlers, and I had best luck with Kimber Select (either 3033 or 3038), the Kimber cable geometry working very well to control the woofers (reviewer Anthony Cordesman confirmed this in his review of the Mahlers for Audio, available at Sumiko's website).
The Stereophile and Audio reviews of the Mahlers available on Sumiko's website (www.sumikoaudio.net) are both accurate in my experience and do a good job of describing the Mahler's strengths and weaknesses. In many ways, I prefer the Mahlers over the Revel Salons I use in my main system. Like the big Sonus Fabers, they have an inviting warmth that gives life and body to stringed instruments. They also have enormous slam and dynamic range, and beautiful cabinets.
