For car stereo, not for home stereo ! Amazon fails to describe the true nature of this product. This is an automotive audio device. good... while it lasted with these subs i also bought a 4000 watt amp that was 2-channel with 2000 watts peak and 1000 watts rms per channel.

Aftermarket Replacement Stylus for Shure V-15 Type III, February 5, 2006 Aftermarket replacement stylus for Shure V-15 Type III, features a.2 X.7 elliptical diamond mounted on a tubular heat-treated aluminum alloy cantilever. The cantilever has a 1.0 mil wall thickness and 20 mil diameter exhibiting very low moving mass. Tracking force ranges between 0.50 to 1.75 grams (5 to 17.5 Newtons), with the optimum at 1.25 grams (12.5 Newtons). Sold as a direct replacement for the Shure VN35E and VN35HE styli, and a functional replacement for the Shure VN35MR stylus. Manufactured by: Ed Saunders, http://www.edsaunders.com. Price as of this review, $45.95 each plus shipping. This project began unexpectedly. I was shopping on the Internet for a replacement stylus for my Shure V-15 Type III, one of my longtime favorite cartridges. My search was for only genuine Shure styli, because Ive found generic styli for the V-15 Type III to be audibly inferior to genuine Shure styli. Unfortunately, nearly all the styli I found were generics, except for one or two new-old-stock Shure styli selling on eBay. Along in my search I encountered Ed Saunders offering a replacement elliptical stylus for the Shure V-15 Type III. Eds description for the stylus was intriguing, and stated it was the exact same as the original Shure stylus. I was skeptical because all the aftermarket styli Ive seen so far had either spherical tips or had very poorly made broad elliptical tips. One especially awful example that I once purchased for $18.90 (and should have known better) would not track any of my audiophile albums and made my V-15 Type III sound cheap, shrill and distorted. I soon contacted Ed, who was very gracious and tolerant of the almost accusatory tone I adopted when questioning him about the stylus. He explained that he was actually the manufacturer, having made the stylus for over ten years, and that the stylus was not one of the well-known generic brands of aftermarket styli. More importantly, he told me the stylus was indeed an exact copy of the VN35E, with a 0.2 x 0.7-mil elliptical tip, described by Shure as biradial. He remarked that he chose the elliptical stylus because he preferred the sound of the elliptical stylus over the hyperelliptical or the microridge. This got my attention, because Ive always preferred the original biradial elliptical Shure VN35E stylus over the newer VN35HE hyperelliptical or the VN35MR microridge. Each of the V-15 Type III styli are excellent, of course, but the VN35E seems more natural and it seems to more accurately render the texture of sounds (such as the woodenness of a guitar or the metallic sheen of cymbals). Ed kindly offered to send me one of his styli if I would write a review of it. I eagerly agreed, and awaited the arrival. The stylus arrived in only three days, which surprised me. Pleasantly. It was packed in a clear plastic box with foam rubber padding. Physically, it looked okay, although the blue label on the stylus grip was trimmed sloppily. This is not a complaint, merely an observation. Test measurements were carried out using a Shure TTR-103 Laboratory Test Record, KVG Labs TR-1 Frequency Response Test Record, KVG Labs TR-2 Harmonic Distortion Test Record, KVG Labs TR-3 Intermodulation Distortion (IMD) Test Record, Shure C/PEK-3 Cartridge Analyzer, Heath IM-22 Audio Analyzer, Heath IM-5258 Harmonic Distortion Tester, B&K dual-trace oscilloscope and Hewlett-Packard 400 audio

Technical Review

DESCRIPTION

INTRODUCTION

TESTING CONDITIONS
voltmeter. The Ed Saunders stylus was measured then compared to a vintage genuine Shure VN35E stylus using an early-production Shure V-15 Type III cartridge made in 1976. The cartridge was mounted on a Dual 1249 turntable for both the measurements and the listening tests. Tracking force was set at 1-gram (10 Newtons). Listening tests compared the Ed Saunders stylus to vintage genuine Shure VN35E, VN35HE and VN35MR styli. The other equipment for the listening tests used two stereos: one system used a Kenwood KA-7100 integrated amplier with JBL 4311 loudspeakers, and the second system used a KVG Labs 76EQ phono preamplier, KVG Labs 60A 40-watt power amplier with KVG Labs L-81G loudspeakers. Ten listeners, including the reviewer, listened to the styli and both stereos, involving 47 different LPs and 22 different 45 rpm records, covering every almost genre of music and level of record quality. The listening tests were informal and asked only for broad preferences. No scores were taken and no statistical tests were calculated, because such was deemed unnecessary. Ed Saunders stylus

TEST MEASUREMENTS

Peak Measured Velocity: 400 Hz 26 cm/sec 26 cm/sec 1000 Hz 38 cm/sec 38 cm/sec 5000 Hz 35 cm/sec 35 cm/sec 10,000 Hz 26 cm/sec 26 cm/sec Output Voltage: 3.37 mV 3.53 mV Measurement referred to 5 cm/sec peak recorded velocity at 1000 Hz. Channel Balance: 2.1 dB, left 1.9 dB, right Measurement denotes toward which channel the imbalance leaned. Frequency Response: 12 - 24,000 Hz +/- 3 dB 10 - 25,000 Hz +/- 3 dB 25 - 16,000 Hz +/- 2dB 20 - 14,000 Hz +/- 2dB 40 - 10,000 Hz +/- 1.5dB 40 - 10,000 Hz +/- 1.5dB THD, 1000 Hz, at 5 cm/sec: 0.87% 0.83% IMD, 700+3500 Hz, 4:1 1.2% 1.1% The listener panel, as expected, was split among who preferred the biradial elliptical styli over the hyperelliptical or the microridge. The vote was unanimous, though, that the Ed Saunders stylus was indistinguishable from the genuine Shure VN35E. Despite my initial skepticism, the Ed Saunders replacement elliptical stylus for the Shure V-15 Type III is excellent and every bit the equal of the Shure factory stylus. The sound is the same under real-world listening conditions and the diamond tip is made good enough that wont prematurely wear the records, unlike other aftermarket styli. The price is a fraction of the cost of new-oldstock Shure styli and is less than most other aftermarket styli. The Ed Saunders stylus will keep your V-15 Type III sounding sweet, detailed and accurate for years to come. If you have a Shure V-15 Type III that you still enjoy and need a replacement stylus, Id recommend you buy it from Ed Saunders unless you enjoy paying $200 for the privilege of having Shures name on the box. If all you care about is the sound, then you cannot go wrong buying Ed Saunders stylus. As for myself, I will not hesitate to buy a stylus from Ed for my other cartridges as well, like my Ortofon VMS-30s nude ne line stylus.
