Hi, I own a pair of the 938 Hyperions. They are the best speakers I have ever owned, but then again I have not auditioned the other two speakers in its price ranged mentioned in this thread.
If it is worth anything , I can tell you my thoughts on how it compared to my megabuck Avantgarde DUO's with modified bass units for improved bass performance (over the much critised standard bass units). After a weeks constant burn in I sat down and listened to my first reference CD. My very first impressions were 'yes, well done Luke, much better than the duo's'. Why?, well they imaged in proportions that seemed more realistic. The Avantgardes had huge images of each musician. The 938 captured the hall ambience and detail. There was more transparency in the midrange, YES that is more transparency. I was able to feel and see the instrumentalists better due to better resolution of inner detail and tonal colours.I was free of that artificial etched quality the Duos always had me nit picking at. The bass, well quite frankly even in its modified upgraded form the duo's bass was either a joke or the 938's had superb bass. They were also seemless from top to bottom. Compared to the duo the dynamics were not far behind at all to my major surprise. I really never once felt that there was a trade off with dynamics! You simply forget you are listening to a speaker and concentrate on the music. That is the first time I can say that has ever happened to me. My previous speakers were Audio Physic Avantis, Harbeth monitors, all much much dearer than the |Hyperions.
I have numerous set ups, that is numerous valve and power amps to switch and change with. Si each speaker hada good run for itys money.
