YG Acoustics speakers have always had a distinct look, but the massive aluminum towers in room 806 were unmissable, even if you only glanced into the room. These were the Colorado-based manufacturer’s state-of-the-art Sonja 3.3 loudspeakers.

Angie Lisi of American Sound of Canada always presents desirable components—CAF2024 was no exception. This year, Lisi launched the North American debut of German-made Perpetuum Ebner turntables, the new Phasemation SA1500 integrated amp, new Avantgarde Colibri Series speakers and subwoofer, new Avantgarde Zero Itron speakers, and her exclusive line of Italian Synthesis Art in Music tube amplification.

This all-Infigo-meets-Alta room was bathed in Infigo Audio’s Hans Looman’s usual blue light glow, showering the room with the same mystical vibrations I heard from this room at some CAF long since past.

I remember the first PS Audio product: a simple phono stage. It was so simple—a passive RIAA EQ filter flanked by a pair of primitive op-amps—that when the schematic was made public, I built one myself; I was in the midst of my DIY years. I thought it was, to use a word from that time, nifty. Paul McGowan went on to other things and other companies, eventually reviving PS Audio and building it into its present form with a wide range of interesting and substantive products. Most recently, PS Audio added a line of loudspeakers inspired by Paul's erstwhile partner in other ventures, the late Arnie Nudell.

The PS Audio Aspen speaker line has four models, three 3-way floorstanders (FR30, FR20, FR10) and a single two-way standmount (the FR5, $3499/pair).

Harmonia Distribution brought a respectable system to CAF, including a Grimm Audio MU2 Media Player Streamer Preamplifier ($17,500), PrimaLuna EVO 400 Tube Preamplifier ($4995), and a product I raved about at Stereophile and continue to use, the PrimaLuna EVO 300 Hybrid Power Amplifier ($7195).

What’s in a name? Joe Finn of Timonium, Maryland’s Gramophone clearly knows the answer. He brought a compact system to CAF, one stocked with overachieving gear and equally ambitious cables, courtesy of AudioQuest.
