"This is the first Tweak I've used to make such an immediate audible difference in my system. It literally bought the music into focus, like the fine adjust knob on a microscope. I didn't want to get (the Cones), but after listening to my system with and without them, it was no contest. DH cones were in for good! Terrific product - efficient, affordable and a real sonic improvement."

Wayman Wong, San Francisco, CA

"To be honest, I wasn't expecting much difference when DH cones were put underneath audio equipment, what difference could some cone make? My first listening session with DH cones underneath my CD player change my thinking. What I heard was lots of musical detail, tighter bass, better sound stage and fuller body of sound. The music was more vivid, palpable and immediate. I got use to the sound. When I took out DH cones, the music sounded wash out."

Michael Saft, North Potomac, MD

"They make my CD sing."

Robert Williams, Phoenix, AZ

"Like a good Tripod under a good camera, DH cones improve the focus, images became more clear...more real. A great cost effective upgrade."

Steven H. Roth, San Francisco, CA

"DH cones- The finishing touch for the finest sound - Just when I thought I was done - all cables and conditioners in place - comes an improvement in musicality that is just remarkable - DH cones. They are like a certain Potato chip - you can't eat just one. I have them under all of my components -even the ones with no moving parts. What did I get? Better sound stage, fuller tone, more realistic sound of instruments, better pace, more music. What did you get? A very satisfied customer."

Michael Sternberg, MD, McLean, VA

"We listened to the Golden Tube SE-40 amps with and without DH cones. Without DH cones, the amp. was pleasant, lacking in bass and somewhat bright in the upper mid range. With Cones, bass became more extended, detail emerged and brightness decreased. The combination of increased detail, with decreased brightness is a trick usually afforded to only the best and usually expensive components. The results is natural music, rather than electronic reproduction."

Wayne E. McNeil, Prescott Valley, AZ

"The cones were brought to my attention by the audio dealer which is a short distance from my residence. I will have to admit that I acquired them with a tongue in cheek attitude and placed them under my preamp and DAC. Without having to question was there a difference or not, I immediately heard a much smoother high end and a tighter bass. I was able to play my system at a higher volume which allowed the bass to operate at its fullest without having to turn the volume down to eliminates a condition of listening fatigue due to too bright upper end. As I was listening to the cone I had told the salesman I would bring them back on the weekend and he said you won't be bringing them back and he was right."

"It has been a dilemna for more than 10 years, deciding whether to tolerate the edgy, bright sound of cones or the muddled, mushy sound of sorbothane. Having auditioned a wide range of metal cones and sorbothane feet with less-than-satisfying results, I naturally approached the DH cones and squares rather cautiously. I was very surprised to find the DH jumbo cones on DH squares miraculously combine the relaxed smoothness of sorbothane feet, with the detailed airiness, tight bass and precise soundstage of metal cones. Truly the best of both worlds. Compared to the various footer solutions I have used, the DH combination provided an astonishing increase in definition of acoustic space and instrument location in orchestral music, deeper and more powerful bass whack on pop, greater presence in Jazz, and an overall clarification that made musical performance sound more alive, heartfelt and spirited. Putting back my old cones and Audioquest feet, the relapse to a mechanical lethargy was damningly apparent on my Grado RS-1 headphones. This was hard to bear after the revelation of DH cones & squares."
