AudioKeyReviews: SQM is incredible!

July 15, 2024

When K.E. Heartsong of AudioKeyReviews auditioned our SQM line cables he did not yet know their price. When we sent him the pricing information afterwards he was “truly and profoundly shocked” as he writes. Please read his burning review about SQM in the beautiful AKR online magazine of July on page 118. As an appetiser, we copy some quotes below.

“Placing the SQM XLR balanced cables in the Reference Headphone system, absent the benefit of complete burn-in, was nonetheless an eye-opening, mouth-agape epiphany. All the cables that were not considered reference or Top-of-the-Line (TOTL) cables in a manufacturer’s offering were quickly and soundly surpassed in all technical, musical, and immersive abilities. It was not even close, and this called for several minutes of quiet to determine what had just happened. 

(…)

“But how do the SQM cables actually sound?” you ask. Well, the short answer is that they sound very much like the TOTL cables that I have written about across these pages, though at relatively speaking bargain basement prices. There is, however, the added quiet, a quite profound naturalness, and the meticulous staging of your music, that “sorts” out musicians in and across a given venue to its depths, width, and their relative spacing that few cables have achieved. 

(…)

Yes, the Grimm Audio SQM cables are mind-boggling, as they compete, no scratch that, out-compete Top-of-the-Line (TOTL) cables at many multiples of their cost in a way that defies any semblance of, well, “logic.” One would not think this possible, given the vast disparity of cost between them and the TOTL competitors, but on every metric of music reproduction—technical/spatial, natural musicality, immersiveness— the SQMs were consistently on top. Incredible!

(…)

The Grimm Audio SQM cables are clearly and easily Diamond Award winners of the first degree and, dare I say, Breakthrough Award winners as well.”
