240 - What is Quality?
Good for you for having a McIntosh 240. From time to time, one hears discussions of "what's a classic?" and "how do new designs measure up to vintage gear?" I can't provide a definitive answer. Perhaps the story of my McIntosh 240 provides a clue, however.
According to the paperwork that came with my 240, it was purchased in 1965 in Chicago. At some point, it made its way to Atlanta. I purchased it (via the Internet) from someone there in 1995 (some 30 years later). It needed some capacitor work, and one new tube socket. Since 1995, I've used it regulalry, and in some cases every day. I've changed tubes (replacing the 6L6GC set with Groove Tubes (Saratov?) KT66's). I use the unit frequently, trying to get a least one worthwhile session of music (via CDs, LPs, SACDs, DVD-As, FM, and Dolby B and DTS-encoded disks) each evening, or at some point during the day on weekends. I drive Maggie 1.5 speakers (with a powered Hsu Research subwoofer). A Cary P-7 preamp provides control functions, with other gear for home theater.
I grew up with live music, and I've listened to music most of life. I find the McIntosh capable of providing imaging, detail, and "bloom" worthy of a live performance. Guests to our home are often astonished. At one point in the last 12 months, guests who entered the house during the playing of a Brubeck DTS-encoded disk, started searching for our piano (don't have one, but might get one).
Some 38 years after its first purchase (and possibly its manufacture), our McIntosh 240 is going strong, providing superb service almost every day, with a full range of media (from LP through today's hi-resolution formats). This kind of record is a sort of personal performance test for "classic" or intrinsic "quality." Very few of our electronic possessions seem to rack up this kind of record. I can't imagine the day when it would be "retired."
Enjoy that McIntosh 240 !!!
