A few issues back, in my review of the Mark Levinson No.26 and No.20 (May 1988, Vol.11 No.5), I mused on the fact that the preamplifier, being the heart of a system, had a more significant effect on sound quality in the long term than, say, the loudspeakers. It was worth spending more on a preamplifier, therefore, than on loudspeakers. Needless to say, this viewpoint was regarded by many readers as dangerously heretical. I decided, therefore, to investigate the sonic possibilities of budget-priced preamps in this issue, even the most expensive being less than one-tenth the price of the Mark Levinson.

The super cool Rudy Dupuy of Dupuy Acoustique (in Congers, NY) says he used to make loudspeakers, but then he realized that the time-delayed and out-of-phase reflections from the wall behind the speakers always sabotaged any hope of loudspeaker coherence. So he stopped making speakers and developed the tunable Phase Restoration Acoustical Panel (PRAP).

On the morning of November 9th, 2018, Stereophile's caffeinated crew of Jim Austin, Sasha Matson, Herb Reichert, and myself arrived at the New York Audio Show with the intention to invade each exhibitor's room as an opinion-bearing, glad-handing tribe. ("Hello—we've come from Stereophile to put fear into your heart and a quick step to your cueing finger. Now play me some Nils Lofgren!")

The great debate that has long separated audiophiles is tubes vs solid-state. Other topics, CD for example, may temporarily steal the spotlight, but year-in and year-out no other subject is the cause of as much controversy as whether tubed or solid-state circuitry produces the more accurate sound. As is typical with long-standing feuds, the split runs deep, and tempers often flare.
