I would like to report an anomaly. Although I am a Klipshorn fan through and through, probably would love the Jubes, have liked several of the big JBL systems, etc., AND have found most BOSE 901s, in most systems, to be muddy and inferior .....
Some VERY strange things can happen with the BOSE 901 ......
Sometimes they are strange and beautiful.
From 1972 to 2003, I visited the best sounding BOSE 901 system in the world (I'll just bet) approximately once every 4 years. It was in Alphonso's Mercantile in Mendocino Village, CA, overlooking a finger of the sea (Alphonso seemed to be in ill health the last time I visited, so I don't know if he is still alive, or if his store is still there). What a store it is/was! He collected classical and contemporary orchestral music from all over the world, always had it playing, and presided over it all with the multi-volume Oxford Encyclopedia of Music and glass of wine. In his dumpy little "L" shaped store he had a pair of BOSE 901s c1972, and always supplied them with the best amplification, starting in 1972 with a Phase Linear 700 and a Marantz (one of Saul Marantz's!) pre-amp, on up through a 1,000 wt RMS McIntosh amp in 2003. He went through many sets of electronics and players, but never replaced his BOSE 901s. They survived the transition to CD in about 1984 very gracefully. Every time I went there I was struck by how great the sound was, and every time I returned home, with a large bunch of Lps or CDs that I had been introduced to by Alphonso, I failed to equal the sound at home! Often, while my Klipschorns would create greater and more exciting dynamic range, or a bit more detail and sheen in the brass, they never seemed to have the integrated, organic whole sound of Alphonso's 901s. Neither could the JBLs, or ADCs that preceded my Khorns.
Now, don't get me wrong, I've heard plenty of BOSE 901's that couldn't hold a candle to my Klipschorns, but Alphonso's always could do at least a bit better. Why did his BOSE system sound so much better than the other (maybe 7 or 8) BOSE 901 installations I've listened to carefully, for prolonged periods?
Speculation:
Over the years I've noticed that most 901's I've seen were installed farther out from the wall than Alphonso's are (his are, maybe, 1 foot out and there is a corner nearby). He always had at least 350 wpc RMS amplifier power -- none of the other installations did. He always played the music fairly loudly (real orchestra level), but so do I. The magic of the ocean lighting, the wine, and the general conviviality altered my perception of the music?
Alphonso played music no one else could find, including Mystery of Time during the hiatus when it was no longer on Lp, and not yet on CD. I hope he is alive, well, and raising his glass to the sea!
