PREAMPLIFIER
Given the Swiss company's steady ascent in the high-end pantheon, it is high time that we again reached into the German-speaking region of Switzerland north of the Swiss Alps to evaluate another of the reference products from a company equally renowned for its sonic achievements and refined and elegant design aesthetic.
Enter the full-function Soulution 727 preamplifier ($74,975),² whose optional MC/MM phono section ($11,975) will be evaluated in a future issue.³ Because Soulution claims that the 727 "sets benchmarks in terms of noise, phase errors, common mode rejection and distortion," one would hope that there's far more than 62lb of classy casework and an easy-to-handle lightweight remote to account for its price.
The 727 is the top-level preamplifier in Soulution's threetiered lineup of Series 7, Series 5, and "entry-level" Series 3.
Its front panel is intentionally simple: three large, slightly raised Power, Mute, and "Prog" (program) buttons on the left; a display in the middle, whose readout is clearly legible from a distance of 12', and a large rotary knob on the right that handles volume, input selection, display brightness, and programming/configuration adjustment.
The rear panel, whose layout is almost as elegant as the front's, includes a 15-amp mains input, two pairs (one for each channel) of balanced outputs, one pair of RCA outputs, three pairs of balanced inputs, and two pairs of RCA inputs. Add in an RS-232 port; two "LINK 3-Series" sockets for use with Series 3 units; link-in, firmware, and link-out ports; and a model-identifying panel that includes the serial number, and you know what's on the surface. Settings and configuration choices include balance, phase, ground lift, start volume, maximum volume, and input selection/deactivation/naming.

Listening to music inspires us to take action. Upon hearing an I.E.-Instant Earworm-we must then determine the best way we can go about listening to it again (and again) at our convenience.

In my review of the T+A R 2500 R receiver (August 2024 issue), I covered many of its features and took as deep a dive as time and column inches allowed.
Audia Flight FLS10
The dogma of separates has long reigned supreme among audiophiles: If you're serious about sound quality, you're supposed to need a dedicated preamp and power amp.
Totem Acoustic Element Fire V2
Totem Acoustic was founded in 1987, in Montreal, Canada, by a former high school math teacher named Vince Bruzzese. The company's first product, the Model 1 loudspeaker,' impressed me so much I bought a pair.

The Spin Doctor checks out the Kuzma Safir 9, a superarm from Slovenia.
The British audio scene from the late 1970s through the mid-1980s was pretty strange. Audio as a hobby was a big deal, with widespread appeal to a much younger crowd than today. Audiophiles were guided by a flurry of what my friends called \"hi-fi pornos,\" audio magazines that filled the racks at the newsagents.
Alex goes to Japan
Arriving in Japan from the United States is like being turned upside down. This condition lasts for much of the first week. When I visited in November, the time difference between Tokyo and New York was 14 hours. \"The floating world\" is a term for the pleasure-addled urban culture of Edo-period Japan, but it's also an apt description for the twilit and not-entirely-unpleasant weirdness of first arriving in Tokyo. Everything seems slightly unreal.
