@fleschler Sounds like you heard a classic mismatch of gear that had little synergy. When i heard the Alexx V's, they were in a huge room ( 45'X30'!) partnered with D'agostino amps/ preamp and a MSB Select 2 DAC. Superb sound with a huge soundstage and amazing dynamic impact/scale. However, whenever I have heard McIntosh amps, I hear what you describe, so that is where I would expect the results you heard.
How big was the room you heard the Alexx V's in? I think anything smaller than about 25' x30' would be a limiting factor for these large speakers!
