Stax SRM-001
A tiny energizer that shipped as half of Stax's oddest portable electrostatic kit. The documentation is as scarce as the unit itself.
Overview
The Stax SRM-001 is one of the more elusive pieces in the company's energizer lineup. What the surviving record actually establishes is narrow: the SRM-001 was the driver/energizer half of the SR-001 MK2 system, a bundle Stax listed as the "SR-001 MK2 (S-001 MK II + SRM-001)." That parenthetical is the whole story as far as the archive's documentation goes — the SRM-001 is paired in Stax's own listings with the S-001 MK II, and the two together constitute the SR-001 MK2 system.
That pairing appears in dealer listings from the early 2000s. Audio Express, the Japanese export dealer whose catalogs circulated to overseas buyers, ran a Stax price table across multiple 2002 and 2003 issues. It lists the SR-001 MK2 as a line item alongside the company's full-size systems - the OMEGA II System (SR-007 + SRM-007t), the SRS-5050 System W MK II, the SRS-4040 Signature System II, the SRS-3030 Classic System II, and the SRS-2020 Basic System II. In those tables the larger systems carry "Ask" or blank pricing, while the SR-001 MK2 sits at the bottom of the list as the entry-level entry. The tables were a recurring fixture of the export market in that period. The SR-001 MK2 shows up in the March 2002, June 2002, July 2002, August 2002, June 2003, and August 2003 issues, so the system was a live catalog item through that window. Audio Express catalogs from that period also carried cartridge listings such as the Denon DL-102 (MONO) at $150 with air-economy postage of $18 to Area I destinations including China, Korea, and Hong Kong (Audio Express, March 2002, p.27). The same catalogs advertised Japanese audio books, including Attractive Tube Amps Vol. 1&2 by Isamu Asano at $30 each and The Joy of Vintage Tube Amps 1&2 by Tadaatsu Atarashi at $30 each (Audio Express, June 2003, p.17).
The material the archive holds does not document what the SRM-001 itself does - its topology, its output, its input provisions. The chunks that name it are price tables, not spec sheets. There is no service manual excerpt, no owner's manual page, and no period review measurement in the record. Anyone claiming a specific output voltage, bias arrangement, or connector type for the SRM-001 is working from something other than the sources here.
Shoppers should keep this in mind. Stax sold them as a set and the archive has found no evidence of separate retail distribution, so a lone SRM-001 should be treated as a component pulled from a system rather than a product with its own retail history.
Beyond that, the SRM-001 is under-documented. No production years, no original price, no measured performance, and no independent review have surfaced. The archive would welcome an owner's manual, a spec sheet, or a set of measurements from anyone holding them.
