Stereophile Recommended Components - October '98

Pass Labs Aleph P: Class A

Well-built remote-control preamp that SS avows stands as proof that "simpler in indeed better", praising it as the "quietest active preamplifier I've ever reviewed". Also drawing comment from the Stone from Boulder were its dimensionality, transparency, bass extension, top-end air, and low-level detail. In short, "the Pass ruled". "Will appeal to anyone who values clarity and accuracy over euphony and frills", he concludes. (Vol.19 Nos 2&10)

 

Pass Labs Aleph 0 monoblock: Class A

With the exception of JE, the magazine's reviewers were pretty much unanimous on the virtues of this single-ended, 90W, MOSFET-output Nelson Pass design: true Class A. Neutral-balanced rather than euphonically sweet in the manner of a classic single-ended triode design, the Aleph 0 offers superbly transparent, musically natural detail retrieval and superb dynamics -"Class A with a bullet!" sez he. Low input impedance mandates careful preamplifier matching. (Vol.18 No.3, Vol.20 No.11)

 

Pass Labs Aleph 1.2 monoblock: Class A

Single-ended solid-state 200W monoblock power amplifier drove SS to proclaim, "If you purchase any high-power tube amp without auditioning an Aleph 1.2, you've failed to fully investigate your options.... They're hot, they're happening, and they're pretty damn awesome. But exactly what qualities make [them] so sonically stupendous? [Their] lack of any sort of electronic signature....midrange to die for...[and] unflappable suavity." (Vol.20 No.11)

 

Pass Labs Aleph 3: Class A

Single-ended, solid-state, 30Wpc, class-A stereo amplifier that caused MK to throw down the gauntlet: "I positively dare all of you to go out and hear this amplifier for yourselves - even if you currently own much more expensive amps (heh-heh-heh)." JA, intrigued, did; then he lauded its "wide, deep, detailed soundstages; a delicious presentation of recorded detail without getting in your face; a purity of tone that became addicitive; and an ability to go loud.... that belied the 30Wpc specification." Low sensitivity and power rating demand careful system/room matching, but magic has always careful preparation. (Vol.20 No.4, 11, & 12)

Stereophile's AMPLIFICATION COMPONENT OF 1997
Aleph 3
($2300; reviewed by Muse Kastanovich & John Atkinson, Vol.20 No.4, April 1997)

Worlds apart, apparently, stands the Pass Aleph 3. Yet it, too, has a winning lineage: the Pass Aleph 0 was Stereophile's "Amplification Component of 1995". Comparing this amplifier to those in Class A of Stereophile's " Recommended Components," reviewer Muse Kastanovich called for a higher classification to be created for such products as the Aleph 3.
