Vienna Acoustics Mahler

The Mahlers are three-way, floor standing, reflex-loaded dynamic loudspeakers.  Retail was $10000
This speaker has a great midrange with voices having an incredible richness. You can listen for hours. The highs are appropriate and not overly shiny or harsh. The bass - well you do not need a subwoofer. This system has a refined low bass. Great speakers! Will miss them!  You can use tubes or solid state amplifiers.
Constructed of only the finest raw materials and component parts, MAHLER “no limits” approach has resulted in a true state-of-the-art loudspeaker system. Unbridled by price-point constraints, the stated design goals were ultra-wide bandwidth, exceptional dynamic range, extended “subwoofer-like” bass response, smooth and detailed midrange and high frequencies and lastly very high efficiency.
