Anthony Gallo Acoustics Reference Strada Speakers and TR3 Subwoofer

John E. Johnson, Jr.

Anthony Gallo Acoustics has been known for many years to make very unique, high performance loudspeakers that can deliver world-class performance at reasonable prices and in everyday rooms. I was so impressed with their Reference 3.1 speakers when I reviewed them in 2007 that I bought the review pair. In the past several months, Gallo has significantly upgraded their reference line. The Reference 3.1 has just been replaced with the much more expensive Reference 3.5, but a new speaker system has taken up a new position in the Gallo line at a price point very close to the old Reference 3.1.

Marantz SA-KI Pearl SACD player

Robert Kozel

The Marantz tradition has always been about enjoying music. The Marantz SA-KI Pearl is a limited-edition SACD player from the Marantz Reference Series product line. The "KI" in the product name refers to Ken Ishiwata, who is the actual designer of the SA-KI Pearl. Ken Ishiwata has an impressive biography. He fell in love with music as a young man. He pursued a career in fashion photography following in the footsteps of his father. In the late 1970's, Mr. Ishiwata started his career with Marantz. Today, he is an accomplished violinist, audio engineer, electronics engineer, and brand ambassador for Marantz in Europe.

Mystere pa21 Stereo Tube Power Amplifier

John E. Johnson, Jr.

Durob Audio is a company in the Netherlands that markets PrimaLuna tubed audio components, including integrated amplifiers, power amplifiers, and a CD player that has a tube-based clock. It also has a discrete output stage with triodes running in pure Class A. Conventional CD players use op-amps in the output stage. Although the tube output stage and op-amp output stage sound different, one doesn't necessarily sound "better" than the other, although tubeophiles would all opt for the "better". We reviewed the PrimaLuna DiaLogue Two integrated amplifier in December, 2009.

With the introduction of Durob Audio's Mysterè line, we now review the Mysterè pa21, which is a 55 watt per channel stereo tube power amplifier. The Mysterè line goes beyond the PrimaLuna line with larger transformers, more power supply capacitance, and an auto-bias circuit that lets the consumer choose between using KT88's or EL34's as the output tubes.
