Dear kevemaher, you are an audiophile extraordinaire, and you merit admiration by nearly all of the rest of us. What I think you’ve revealed is that traditional measurements, such as those you have made, don’t tell the whole story. Else why can we yet hear difference among cartridges, turntables, tonearms, and all the rest of the gear that measure so similarly? You also in passing reveal the “dirty little secret” of audiophilia, that in fact we often don’t know what we’re doing. One reason the DQX1000 should be obviously superior sounding compared to the DD40 would be that the former TT incorporates a quartz crystal reference which ought to enhance its performance vs the DD40. Have you assessed speed constancy? Virtually every DD table made since the heyday of the DQX1000 uses a quartz crystal reference. I think Denon were the first to do that, in their DPXX series.
ZYX "House" Sound
I am searching for a different sound in my system. I'm currently using the Shelter 901 MkIII and the Koetsu Rosewood Signature. I consider both to be on the warm side of neutral. I'd like to find a very good quality cartridge that is a bit more neutral. I don't want "clinical". I cannot cope with cymbals that sound like white noise with emphasis on the upper octaves. System is: MS DD-40 (2 tables), SUT using the Cimemag 1254 Tranny, Paragon Model E tube preamp (used as a phono pre) and Musical Surroundings Nova phono pre, Levinson control amp, Bryston 2.5B cubed power amp, Revel bookshelf speakers and HSU sub.
I've been seriously considering ZYX for my next cartridge. There are reviews of the top and bottom of the line ZYX cartridges, but little in between. I've contacted Mehran at Sorasound. Based on my budget, he suggested the Ultimate (Exceed) 4D or the Ultimate (Exceed) Omega.
Not many reviews for these mid-tier cartridges. Is anyone familiar with the sound of these cartridges? Does ZYX have a "house" sound? I'm not concerned by the naming confusion nor any of the other negative comments I've read. They're not constructive. I really want to understand where the ZYX cartridges fit in the cool to warm spectrum. There may be other brands to look at, and I'm doing that. This post is about the ZYX sound.
