I was all ready to spend up to five hundred dollars to buy Bose or Cambridge Works. I studied all the online reviews. A lot of people who seemed serious recommended the Logitech Z-2300 as being just as good. So I decided to buy that one since it is so much cheaper, but it seemed to be discontinued, and Amazon said that the Logitech Z623 is its “successor”. One of my requirements is the low end frequencies. I like pipe organ music, and the pipe organ plays down to the bottom of human hearing. An eight foot C is about 69 Hz, so the sixteen foot is 34 Hz and the 32 foot is 17 Hz. Logitech advertises that the Z263 goes down to 31 Hz, the Cambridge is similar, and Bose does not release the information. So I bought the Z623 on sale from Best Buy and hooked it up.
There is a lot of talk in reviews about different ranges of hearing, and others talk about personal taste, but I use the “closed eyes” test. I listen to classical music, not artificial music, and I close my eyes and ask myself if it sounds as though an instrument is in the room with me. Does it sound as though there is a piano there, or a string quartet, or a pipe organ in the room with me?
I started with Bach’s Passacaglia in C minor. It sounded to me as if I were in a recital hall with a pipe organ. I tried Sibelius Fifth Symphony, Rachmaninoff piano music, Brahms piano music, and various Mozart chamber music. I tried Mars by Holst, and piano concerti by Brahms and Rachmaninoff. I also tried vocal music by Palestrina and Josquin. When I close my eyes, I am unable to tell that I am listening to an IMac computer and speakers instead of live musicians. Some orchestral music sounds thin, but other recordings sound perfect, so I believe it is the recording that is at fault (or the compressed version on my computer) instead of the speakers. I haven’t done a blind test, but from what I perceive, I don’t think I could tell the difference between piano music on these speakers and the seven foot grand piano in my living room. Each time I listened to a piece, when I opened my eyes, I was surprised to see a desk, a computer, and some speakers.
