Tonight - lights off - complete quiet - I listened with the SR-71A to an hour of music - a variety of musical pieces just to hear the quality of sound from different genres..
These included -
Copland: El Salon Mexico (Bernstein conducting)
Bruckner: Locus Iste ( Motet)
Billy Cobham: East Bay (Life and Times Album)
Chick Corea, Stanley Clarke, Lenny White, Joe Henderson, Freddie Hubbard - Why Wait (Griffith Park Collection Album)
Sibelius: Violin Concerto - 2nd MVT (Christian Ferras -vln , Karajan conducting)
Frank Sinatra: My Way (70's recording)
Mahavishnu Orchestra: Miles Beyond (Birds of Fire Album)
All equally presented with plenty of kick, bite, subtlety, sonorous detail, wide sound-staging and naturalism...
Most impressive for me was the old recording of the Sibelius VLN Concerto - I have heard this recording hundreds of time...it is one of the albums I know better than countless others that I know very well ... because it is an OLD recording from the mid-1960's - it has always been presented to me through various hi-fi eq. as if watching a flat screen TV - the sound is arranged two dimensionally . I listen to this recording because it is the very best interpretation of the violin concerto that I know of. It is a personal favourite of mine...
The SR-71A not only presented this music that I love dearly in full three dimensional glory but the coloration of instruments, the directional projection of register and the REALness of the violin came home to me. I have never been more happy than this moment. To hear music I love - brought to me in the most natural realistic sound-scape both acutely present and far enough to hear the sound within an acoustically open space - total inspiration. I could not have spent my money more wisely than in buying this amp...
I think there can be no greater compliment than to say that this amp brings the reality of the recording to you - as it must have been heard by the people making the recordings ... such reality is what I would have thought is the truth of why we record and playback music...
