The Story of "X" (V15 VxMR)

In Reply to: Re: Shure V15VxMR versus Dynavector DRT XV-1: Some measurements... posted by Prism on May 24, 2004 at 05:46:06:

Exactly - Shure intentionally rolled-off the treble a tad to give a "smoother" or "warmer" musical presentation. When one considers how "hot" the treble can be on a wide range of loudspeakers, not to mention the records themselves, this makes a good bit of sense. Shure indicates this tweaked freq response by using the "x" in the model designator.

The marketing materials, however, tell two conflicting tales:

"Frequency Response: Essentially flat from 10 to 25,000 Hz

FLAT FREQUENCY RESPONSE ACROSS THE AUDIO SPECTRUM

The V15VxMR is the premier example of the natural sound of Shure cartridges. Unlike most low-output moving coil products, it faithfully renders the music as it was recorded, neither emphasizing nor de-emphasizing any part of the signal inscribed in the vinyl groove."

On the other hand, they claim:

"The V15VxMR’s detail, warmth and musicality result from its smooth resonance-free output signal..." Note the use of the term warmth.

Shure engineering describes the difference between the V15VMR and the V15VxMR as follows:

"What is the difference? A minor difference in the high frequency response."

Lastly, the pedigree of the V15 V:

"What are the primary differences between the many V15V models?

Answer:

V15V: hyper-elliptical tip; dynamic stabilizer; premium packaging

V15V B : hyper-elliptical tip; dynamic stabilizer; basic packaging

V15 G: spherical tip; dynamic stabilizer

V15V P: P mount; hyper-elliptical tip; NO dynamic stabilizer

V15V MR: Micro-Ridge tip; beryllium cantilever; dynamic stabilizer; tracks at 1.25 grams

V15VxMR: Micro-Ridge tip; beryllium cantilever; dynamic stabilizer; tracks at 1.0 gram; coils and pole pieces reconfigured for a warmer sound."
