I began my July column by talking about how quickly things are changing these days in multichannel audio. What I didn't pay enough attention to is that some things can change quickly enough to create inefficiency. Given that most multichannel digital products are based on digital signal processing (DSP), and many are network-enabled, they can be updated with relative ease. Almost every preamplifier-processor or A/V receiver I've reviewed has needed a firmware update during the reviewing process, and such updates are de rigueur for Blu-ray players, as more and more features (!) are added to new releases. And in addition to providing new performance features, firmware updates often also include corrections for operational glitches that have slipped by the designers and their alpha and beta testers, no matter how assiduously they've done their work.

Big bands died out back in the 1950s, right? They went away when the jitterbug faded and folks began dancing to music other than swing? And then real jazz fans departed when the bebop soloists came along and made big-band players look clumsy and quaint?

I’ve been playing games with myself, attempting to set limits and impose rules around my furious, nearly uncontrollable, record-buying spree. I told myself that for every dollar I spent on a record I would deposit a dollar into my savings account. (I tried it for a few days, but became bored. Saving is not nearly as much fun as record-shopping.) Then, a few weeks ago, after dropping a few hundred dollars during binges at Other Music and the Princeton Record Exchange, I told myself that I would impose a strict moratorium: No more records for me until after the New Year. With few exceptions, I had already purchased just about every new record I wanted, or so I tried to convince myself. But then the new Thundercat album hit stores and I had to have it. And then it was the new Girls record. How could I live without that?

Here’s another:

Today, Peachtree Audio announced their new flagship asynchronous preamp/DAC, the Grand Pre, the first in a series of “Grand” products (a power amplifier and an all-in-one integrated amplifier will come later) and the first Peachtree component to have its design, final assembly, and final QC all take place in the US. For audiophiles hoping to "buy American," this should come as interesting news.

The 14th Annual Blues Masters at the Crossroads will be held on October 21st and 22nd at Blue Heaven Studios in Salina, Kansas.

Girls begin their US tour tonight in Atlanta in support of their sophomore release, Father, Son, Holy Ghost, available now from True Panther.

Long before I became professionally involved with headphones, the Koss Porta Pro was a great little portable headphone. In fact, it was one of the first headphones designed particularly for portable applications. It has remained relatively unchanged to this day ...

... thank goodness. If it ain't broke ...
