Hi Alan;
I have had the Qantum IEC in my system for a few days and am still waiting for the adjustment to complete. While that is happening some characteristics of it are clear; its a mini-Studio directed to a single component. Many of the same improvements I heard from the Studio are present in the IEC and when they are focused on the source it makes a real difference.
Most interestingly I have been hearing a more full sounding presentation with a fuller bass foundation, clearer fuller and way more natural sounding mid-range and upper mids so that the class d amps sound totally like they should on voices and horns! Highs still present with a bit more hit float. This is some of what happened with the Studio (which, btw, had the biggest impact on the entire system of any filter I have bought from you over the years).

Dear Alan,
One month ago, I purchased from you a Quantum/IEC filter, and connected this to my SACD player,having previously connected PE V/IEC's to both my amplifiers, and a PEV/AC to the wall outlet serving the system. Previous to this I had placed various PE's in the different circuits, as well as also adding a PCR v2.
With each addition, there had been delightful increments, which had enhanced the musical experience, but despite or because of these improvements, I did not in any way expect the quality and the extent of the changes created by the Quantum. The improvement was not just in the degree of change, it was something new,something special, and something holistic.
After inserting the Quantum/IEC into my system, I was overwhelmed by the wonderful tapestry of music,but as expected, after some four hours, it all collapsed. But now, some four weeks later,I find that the magic has returned. The rebirth began about two weeks ago, when one afternoon, I sat down to listen to Rachmaninoff's Etudes-Tableux. The swell of the music was almost wall to wall, extending beyond the speaker boundaries. There was a richness in the music, and a blossoming of both the macro- and micro-dynamics, with a 3-D effect.
As well, there is an added transparency and involvement that creates a feeling of being drawn into the music. The presence of my large Duntech speakers, and indeed all the components do not intrude into the experience, they appear irrelevant. In a sense, there really is no soundstage but there is a concert hall stage.
For me, the cardinal change has been a richness of music, but of course not all discs are created equal.
Many thanks for the opportunity to have this experience.

UNBELIEVABLE!!! After approximately 3-4 weeks of the Quantum IEC and PE Quantum filters going through a sonic stabilization and condition phase, the end result was well worth the wait. The Quantum filters dramatically transformed my system from subtle into a BEAST! The end result was a substantial upgrade in dynamics, much better defined bass reproduction (the lower bass now sounds similar to a good subwoofer box), and there was a noticeable drop in the noise floor. The difference in audio quality was astonishing! The system was profoundly improved on every level - tonal pitch, timing (musical pace, speed), inner detail, upper and lower extension, pitch definition, soundstage size, imaging, vocal dynamics and especially the bass output. This innovation lent a fabulous realism to the sound that brought it to an exciting new level of excellence. I couldn’t hear any hint of negativity at all with the Quantum filters on my system. There was simply no comparison before and after … especially in the lower bass reproduction and dynamics. It was like I ended up purchasing a more expensive system. BTW, my Pioneer Elite 60-inch Plasma Display also noticeably improved in picture quality. Alan, kudos!
